jQuery Event when Validation Errors Corrected - jquery-validate

I have buttons that trigger jQuery validation. If the validation fails, the button is faded to help draw attention away from the button to the validation messages.
$('#prev,#next').click(function (e)
{
var qform = $('form');
$.validator.unobtrusive.parse(qform);
if (qform.valid())
{
// Do stuff then submit the form
}
else
{
$('#prev').fadeTo(500, 0.6);
$('#next').fadeTo(500, 0.6);
}
That part works fine.
However, I would like to unfade the buttons once the invalid conditions have been cleared.
Is it possible to hook into jQuery Validation to get an appropriate event (without requiring the user to click a button)? How?
Update
Based on #Darin's answer, I have opened the following ticket with the jquery-validation project
https://github.com/jzaefferer/jquery-validation/issues/459

It might sound you strange but the jQuery.validate plugin doesn't have a global success handler. It does have a success handler but this one is invoked per-field basis. Take a look at the following thread which allows you to modify the plugin and add such handler. So here's how the plugin looks after the modification:
numberOfInvalids: function () {
/*
* Modification starts here...
* Nirmal R Poudyal aka nicholasnet
*/
if (this.objectLength(this.invalid) === 0) {
if (this.validTrack === false) {
if (this.settings.validHandler) {
this.settings.validHandler();
}
this.validTrack = true;
} else {
this.validTrack = false;
}
}
//End of modification
return this.objectLength(this.invalid);
},
and now it's trivial in your code to subscribe to this event:
$(function () {
$('form').data('validator').settings.validHandler = function () {
// the form is valid => do your fade ins here
};
});
By the way I see that you are calling the $.validator.unobtrusive.parse(qform); method which might overwrite the validator data attached to the form and kill the validHandler we have subscribed to. In this case after calling the .parse method you might need to reattach the validHandler as well (I haven't tested it but I feel it might be necessary).

I ran into a similar issue. If you are hesitant to change the source as I am, another option is to hook into the jQuery.fn.addClass method. jQuery Validate uses that method to add the class "valid" to the element whenever it is successfully validated.
(function () {
var originalAddClass = jQuery.fn.addClass;
jQuery.fn.addClass = function () {
var result = originalAddClass.apply(this, arguments);
if (arguments[0] == "valid") {
// Check if form is valid, and if it is fade in buttons.
// this contains the element validated.
}
return result;
};
})();
I found a much better solution, but I am not sure if it will work in your scenario because I do not now if the same options are available with the unobtrusive variant. But this is how i did it in the end with the standard variant.
$("#form").validate({
unhighlight: function (element) {
// Check if form is valid, and if it is fade in buttons.
}
});

Prototype.js event observe click intercept and stop propagation

I have a page that is built around a wrapper with some very defined logic. There is a Save button on the bottom of the wrapped form that looks like this:
<form>
... my page goes here...
<input id="submitBtnSaveId" type="button" onclick="submitPage('save', 'auto', event)" value="Save">
</form>
This cannot change...
Now, I'm writing some javascript into the page that gets loaded in "...my page goes here...". The code loads great and runs as expected. It does some work around the form elements and I've even injected some on-page validation. This is where I'm stuck. I'm trying to "intercept" the onclick and stop the page from calling "submitPage()" if the validation fails. I'm using prototype.js, so I've tried all variations and combinations like this:
document.observe("dom:loaded", function() {
Element.observe('submitBtnSaveId', 'click', function (e) {
console.log('Noticed a submit taking place... please make it stop!');
//validateForm(e);
Event.stop(e);
e.stopPropagation();
e.cancelBubble = true;
console.log(e);
alert('Stop the default submit!');
return false;
}, false);
});
Nothing stops the "submitPage()" from being called! The observe actually works and triggers the console message and shows the alert for a second. Then the "submitPage()" kicks in and everything goes bye-bye. I've removed the onclick attached to the button in Firebug, and my validation and alert all work as intended, so it leads me to think that the propagation isn't really being stopped for the onclick?
What am I missing?
So based on the fact that you can't change the HTML - here's an idea.
leave your current javascript as is to catch the click event - but add this to the dom:loaded event
$('submitBtnSaveId').writeAttribute('onclick',null);
this will remove the onclick attribute so hopefully the event wont be called
so your javascript will look like this
document.observe("dom:loaded", function() {
$('submitBtnSaveId').writeAttribute('onclick',null);
Element.observe('submitBtnSaveId', 'click', function (e) {
console.log('Noticed a submit taking place... please make it stop!');
//validateForm(e);
Event.stop(e);
e.stopPropagation();
e.cancelBubble = true;
console.log(e);
alert('Stop the default submit!');
return false;
submitPage('save', 'auto', e);
//run submitPage() if all is good
}, false);
});
I took the idea presented by Geek Num 88 and extended it to fully meet my need. I didn't know about the ability to overwrite the attribute, which was great! The problem continued to be that I needed to run submitPage() if all is good, and that method's parameters and call could be different per page. That ended up being trickier than just a simple call on success. Here's my final code:
document.observe("dom:loaded", function() {
var allButtons = $$('input[type=button]');
allButtons.each(function (oneButton) {
if (oneButton.value === 'Save') {
var originalSubmit = oneButton.readAttribute('onclick');
var originalMethod = getMethodName(originalSubmit);
var originalParameters = getMethodParameters(originalSubmit);
oneButton.writeAttribute('onclick', null);
Element.observe(oneButton, 'click', function (e) {
if (validateForm(e)) {
return window[originalMethod].apply(this, originalParameters || []);
}
}, false);
}
});
});
function getMethodName(theMethod) {
return theMethod.substring(0, theMethod.indexOf('('))
}
function getMethodParameters(theMethod) {
var parameterCommaDelimited = theMethod.substring(theMethod.indexOf('(') + 1, theMethod.indexOf(')'));
var parameterArray = parameterCommaDelimited.split(",");
var finalParamArray = [];
parameterArray.forEach(function(oneParam) {
finalParamArray.push(oneParam.trim().replace("'","", 'g'));
});
return finalParamArray;
}

In jQuery, how can I create a custom event with a default?

The Event object in jQuery has this helpful preventDefault() method that prevents the default behaviour, obviously.
This is usually used to prevent click events from performing the browser default behaviour.
It seems like it would also be useful for custom events as well.
The task I'd like to achieve with this behaviour is a separate concern but I will explain it as an example for the behaviour I'm looking for:
I have a simple plugin that creates a popup out of a div. I found it on the internet.
$(selector).pop();
I have hacked it to close when you click on anything but a child of the popup, and to prevent default click behaviour on the clicked element.
function closeInactivePop() {
var foundAny = false;
jQ.each(function (i) {
var $this = $(this);
if ($this.hasClass('active') && ! $this.data('activePop')) {
$this.removeClass('active');
foundAny = true;
}
});
return foundAny;
}
$('body').click(function(){
// If we closed any, cancel the propagation. Otherwise let it be.
if (closeInactivePop()) {
$(document).trigger('jQuery.pop.menuClosed');
return false;
}
});
(Now that I paste it I realise I could have done this a bit better, but that notwithstanding).
Now I have added a new plugin that draws a colour picker inside the popup. Except the DOM that this colour picker creates is not inside the popup; it is only inside it visually. The DOM structure is separate.
In the aforementioned hack I would prefer to in fact fire another event, one whose default behaviour is to close the popup.
function closeInactivePop() {
var foundAny = false;
jQ.each(function (i) {
var $this = $(this);
if ($this.hasClass('active') && ! $this.data('activePop')) {
$(document).trigger('jQuery.pop.menuClosed');
$this.removeClass('active');
foundAny = true;
}
});
return foundAny;
}
$('*').click(function(e) {
var $this = $(this);
// This bit is pseudocode, where the Function is the default behaviour
// for this event.
// It is helpful that $this is actually the clicked element and not the body.
$this.trigger('jQuery.pop.menuBeforeClose', function() {
// if we run default behaviour, try to close the popup, or re-trigger the click.
if (!closeInactivePop()) {
$this.trigger(e);
}
});
});
Then I could later do
$('#colour-picker').bind('jQuery.pop.menuBeforeClose', function(e) {
e.preventDefault();
});
And this would prevent the closeInactivePopup default behaviour running when the target of the original click event was the colour picker or something inside it.
Can I do this somehow, even hackily?
I doubt that there is a native way to do that. However, you can either use "triggerHandler()" instead of "trigger()", which provides the ability to return values from the event handlers. Another relatively simple solution is to pass a custom "event" object that can be used to cancel the planned action:
function Action() {
var status = true;
this.cancel = function() { status = false; };
this.status = function() { return status; };
}
$('button').click(function() {
var action = new Action();
$(this).trigger('foo', [action]);
if (action.status()) {
// ... perform default action
}
});​
In the event handler:
$('*').bind('foo', function(event, action) {
action.cancel();
});

MVC Adding methods into jquery.validate.unobtrusive.js

I recently had a question on getting checkbox validation working on the client side within a MVC project. This question was successfully answered, but raised another query.
In order for my checkbox validation to work I needed to add the following bits of javascript directly into jquery.validate.unobtrusive.js:
$jQval.addMethod("mustbetrue", function (value, element, param) {
// check if dependency is met
if (!this.depend(param, element))
return "dependency-mismatch";
return element.checked;
});
adapters.add("mustbetrue", function (options) {
setValidationValues(options, "mustbetrue", true);
});
this worked great, but I'm unhappy about having to change this file just in case Microsoft or the validation plugin boys update the file in the future. If I'm not still working on the project this file may be overwritten without people realising it's been customised.
So with that in mind I tried adding this into an external javascript file:
$.validator.addMethod("mustbetrue", function (value, element, param) {
// check if dependency is met
if (!this.depend(param, element))
return "dependency-mismatch";
return element.checked;
});
$.validator.unobtrusive.adapters.add("mustbetrue", function (options) {
setValidationValues(options, "mustbetrue", true);
});
Unfortunately now the client side script on my checkboxes doesn't run. Can anyone see what I'm doing wrong?
Thanks in advance
S
Sniffer,
The more I look at this, the more I shake my head (at myself).
Upon further review, Darin's method will work, provided that you add one line to his page script:
<script type="text/javascript">
$.validator.unobtrusive.adapters.addBool("mustbetrue", "required");
$.validator.unobtrusive.parse();
</script>
Whenever you make a change (such as adding a new adapter), you must re-parse the unobtrusive validation attributes. Since the last action in jquery.validate.unobtrusive.js is the parsing of the attributes, and the adapter is being added after the parsing, re-parsing solves this issue.
counsellorben
P.S. This solves your issue, but still leaves unresolved the issue of how to add other custom validators which do not use built-in methods from jquery.validate.js without modifying jquery.validate.unobtrusive.js.
P.P.S. I found the answer for adding custom validation methods. In order to add custom validation mmethods without modifying jquery.validate.unobtrusive.js, you need to "borrow" some of its code to add to your page script. Adding a custom method then looks like the following:
<script type="text/javascript">
var $jQval = $.validator,
adapters,
data_validation = "unobtrusiveValidation";
function setValidationValues(options, ruleName, value) {
options.rules[ruleName] = value;
if (options.message) {
options.messages[ruleName] = options.message;
}
}
$jQval.addMethod("mustbetrue", function (value, element, param) {
// check if dependency is met
if (!this.depend(param, element))
return "dependency-mismatch";
return element.checked;
});
$.validator.unobtrusive.adapters.add("mustbetrue", function (options) {
setValidationValues(options, "mustbetrue", true);
});
$jQval.unobtrusive.parse();
</script>
Unobtrusive validation is giving me nothing but grief.
In a very very simple test page, this works:
$(document).ready(function () {
jQuery.validator.unobtrusive.adapters.add(
'mustbetrue', ['properties'], function (options) {
options.rules['mustbetrue'] = options.params;
options.messages['mustbetrue'] = options.message;
}
);
jQuery.validator.addMethod('mustbetrue', function (value, element, params) {
// check if dependency is met
if (!this.depend(param, element)) {
return "dependency-mismatch";
}
switch (element.type) {
case "checkbox":
return element.checked;
break;
case "hidden":
return (value == 'true' || value == 'True');
break;
default:
alert('type = ' + element.type);
return true;
break;
}
});
});
However, when I move this code to my more complex form, suddenly it stops working and I have no idea why and no time to delve into the unobtrusive code to try and find out.
counsellorben's solution works in my more complex form.
If anyone can point me to a site that explains in detail how to properly add a custom validator to unobtrusive validation, I will be forever greatful. Each site I visit has a different solution.
I have no problem adding this code to an external javascript file, which i pilfered from This site
// Custom validator for checkboxs
jQuery.validator.unobtrusive.adapters.add("brequired", function (options) {
//bool-required for checkboxes
if (options.element.tagName.toUpperCase() == "INPUT" &&
options.element.type.toUpperCase() == "CHECKBOX")
{
options.rules["required"] = true;
if (options.message) {
options.messages["required"] = options.message;
}
}
});
Are you certain that you put your script AFTER the jquery scripts in your page? Mine is the last in the list.

Slickgrid - One-click checkboxes?

When I create a checkbox column (through use of formatters/editors) in Slickgrid, I've noticed that it takes two clicks to interact with it (one to focus the cell, and one to interact with the checkbox). (Which makes perfect sense)
However, I've noticed that I am able to interact with the checkbox selectors plugin (for selecting multiple rows) with one click. Is there any way I can make ALL of my checkboxes behave this way?
For futher readers I solved this problem by modifing the grid data itself on click event. Setting boolean value to opposite and then the formatter will display clicked or unclicked checkbox.
grid.onClick.subscribe (function (e, args)
{
if ($(e.target).is(':checkbox') && options['editable'])
{
var column = args.grid.getColumns()[args.cell];
if (column['editable'] == false || column['autoEdit'] == false)
return;
data[args.row][column.field] = !data[args.row][column.field];
}
});
function CheckboxFormatter (row, cell, value, columnDef, dataContext)
{
if (value)
return '<input type="checkbox" name="" value="'+ value +'" checked />';
else
return '<input type="checkbox" name="" value="' + value + '" />';
}
Hope it helps.
The way I have done it is pretty straight forward.
First step is you have to disable the editor handler for your checkbox.
In my project it looks something like this. I have a slickgridhelper.js to register plugins and work with them.
function attachPluginsToColumns(columns) {
$.each(columns, function (index, column) {
if (column.mandatory) {
column.validator = requiredFieldValidator;
}
if (column.editable) {
if (column.type == "text" && column.autocomplete) {
column.editor = Slick.Editors.Auto;
}
else if (column.type == "checkbox") {
//Editor has been diasbled.
//column.editor = Slick.Editors.Checkbox;
column.formatter = Slick.Formatters.Checkmark;
}
}
});
Next step is to register an onClick event handler in your custom js page which you are developing.
grid.onClick.subscribe(function (e, args) {
var row = args.grid.getData().getItems()[args.row];
var column = args.grid.getColumns()[args.cell];
if (column.editable && column.type == "checkbox") {
row[column.field] = !row[column.field];
refreshGrid(grid);
}
});
Now a single click is suffice to change the value of your checkbox and persist it.
Register a handler for the "onClick" event and make the changes to the data there.
See http://mleibman.github.com/SlickGrid/examples/example7-events.html
grid.onClick.subscribe(function(e, args) {
var checkbox = $(e.target);
// do stuff
});
The only way I found solving it is by editing the slick.checkboxselectcolumn.js plugin. I liked the subscribe method, but it haven't attached to me any listener to the radio buttons.
So what I did is to edit the functions handleClick(e, args) & handleHeaderClick(e, args).
I added function calls, and in my js file I just did what I wanted with it.
function handleClick(e, args) {
if (_grid.getColumns()[args.cell].id === _options.columnId && $(e.target).is(":checkbox")) {
......
//my custom line
callCustonCheckboxListener();
......
}
}
function handleHeaderClick(e, args) {
if (args.column.id == _options.columnId && $(e.target).is(":checkbox")) {
...
var isETargetChecked = $(e.target).is(":checked");
if (isETargetChecked) {
...
callCustonHeaderToggler(isETargetChecked);
} else {
...
callCustonHeaderToggler(isETargetChecked);
}
...
}
}

I used the onBeforeEditCell event to achieve this for my boolean field 'can_transmit'
Basically capture an edit cell click on the column you want, make the change yourself, then return false to stop the cell edit event.
grid.onBeforeEditCell.subscribe(function(row, cell) {
if (grid.getColumns()[cell.cell].id == 'can_transmit') {
if (data[cell.row].can_transmit) {
data[cell.row].can_transmit = false;
}
else {
data[cell.row].can_transmit = true;
}
grid.updateRow(cell.row);
grid.invalidate();
return false;
}
This works for me. However, if you're using the DataView feature (e.g. filtering), there's additional work to update the dataview with this change. I haven't figured out how to do that yet...
I managed to get a single click editor working rather hackishly with DataView by calling
setTimeout(function(){ $("theCheckBox").click(); },0);
in my CheckBoxCellEditor function, and calling Slick.GlobalEditorLock.commitCurrentEdit(); when the CheckBoxCellEditor created checkbox is clicked (by that setTimeout).
The problem is that the CheckBoxCellFormatter checkbox is clicked, then that event spawns the CheckBoxCellEditor code, which replaces the checkbox with a new one. If you simply call jquery's .click() on that selector, you'll fire the CheckBoxCellEditor event again due because slickgrid hasn't unbound the handler that got you there in the first place. The setTimeout fires the click after that handler is removed (I was worried about timing issues, but I was unable to produce any in any browser).
Sorry I couldn't provide any example code, the code I have is to implementation specific to be useful as a general solution.

ASP.NET MVC - How to prevent double click submit with jquery.validate.unobtrusive lib?

I need to avoid the double click submitting behavior. I'm using the client validation with the unobtrusive library. I have the following code for avoiding the double clic:
jQuery.fn.preventDoubleSubmit = function () {
var alreadySubmitted = false;
return jQuery(this).submit(function () {
if (alreadySubmitted)
return false;
else {
alreadySubmitted = true;
}
});
};
jQuery('form').preventDoubleSubmit();
Unfortunately, if my form has some validable fields (for example, a required field), the code above is still being fired, hence, even if I correct any mistakes on the form, I won't be able to submit it again.
How can I fire the double click code after the validation has been succesfully done?
You can also use the JQuery One event.
I have found that I could get past most guards against double-clicks by double-clicking fast. Using the one event is the only true way to make sure the event is only fired once. I don't think this technique will work "out of the box" with an input type=submit tag. Instead, you can simply use an input type=button or JQueryUI's .button().
$("#submitButton").one("click", function(event) {
$('#theForm').submit();
});
If you need to re-wire the event on a validation error (or other circumstance), I recommend that you create a function for the event handler. The function isn't necessary in this example because all the event handler does is submit the form, but in more complicated scenarios you may want to avoid repeating yourself.
function submitClick(event) {
$('#theForm').submit();
}
$("#submitButton").one('click', function(event) {
submitClick(event);
});
// This handler will re-wire the event when the form is invalid.
$('#theForm').submit(function(event) {
if (!$(this).valid()) {
event.preventDefault();
$('#submitButton').one('click', function(event) { submitClick(event); });
}
});
You could obviously add the disabling code here if you wanted to give feedback to the user that the button doesn't work anymore. One great side-effect of using the One event is that you don't actually have to make the button disabled, you can use a style of your own.
function submitClick(event) {
$('#submitButton').addClass('disabledButton');
$('#theForm').submit();
}
$("#submitButton").one('click', function(event) {
submitClick(event);
});
// This handler will re-wire the event when the form is invalid.
$('#theForm').submit(function(event) {
if (!$(this).valid()) {
event.preventDefault();
$('#submitButton').one('click', function(event) { submitClick(event); });
$('#submitButton').removeClass('disabledButton');
}
});
JQuery One Event: http://api.jquery.com/one/
I solved it with the following code:
var tryNumber = 0;
jQuery('input[type=submit]').click(function (event) {
var self = $(this);
if (self.closest('form').valid()) {
if (tryNumber > 0) {
tryNumber++;
alert('Your form has been already submited. wait please');
return false;
}
else {
tryNumber++;
}
};
});
NOTE: You can also replace the:
return false;
line, for:
self.attr('disabled', true);
BUT, if you use the name of your submit buttons on your controller for extra logic, they will be sent as null. (you can use an additional hidden field to charge them before submitting)
that's it, hope it helps

jquery newbie: combine validate with hidding submit button
Why not just use:
function disableButtons() {
var form = $(this);
var btns = $("input:submit", form);
if (!form.valid()) {
// allow user to correct validation errors and re-submit
btns.removeAttr("disabled");
} else {
btns.attr("disabled", "disabled");
}
}
to disable your buttons and activate it using:
$("form").bind("submit", disableButtons);
Based on Ryan P's popular answer I created the following generic solution that also works with my ajax form.
decorate your custom submit button with the following class:
<button type="button" class="one-click-submit-button">Submit</button>
Add the following to your javascript file:
function OneClickSubmitButton() {
$('.one-click-submit-button').each(function () {
var $theButton = $(this);
var $theForm = $theButton.closest('form');
//hide the button and submit the form
function tieButtonToForm() {
$theButton.one('click', function () {
$theButton.hide();
$theForm.submit();
});
}
tieButtonToForm();
// This handler will re-wire the event when the form is invalid.
$theForm.submit(function (event) {
if (!$(this).valid()) {
$theButton.show();
event.preventDefault();
tieButtonToForm();
}
});
});
}
OneClickSubmitButton();
since this is an ajax form we want to reload the handlers if we fail server validation.
function MyForm_OnSuccess() {
if (true if your form passed validation logic) {
//do something since your form submitted successfully
} else { //validation failed on server
OneClickSubmitButton(); //reinitialize the button logic
}
}
Obviously if you don't have ajax forms you can omit the whole OneClickSubmitButton function business and run $('.one-click-submit-button').each(... directly.
I have a form that uses MVC3 unobtrusive validation, and a viewmodel with a [RemoteAttribute].
It looks to me like the form's submit event only fires after all validation has passed. I'm currently using this, and it seems to work:
<input type="submit" value="Submit the Form"
data-app-disable-on-submit="true" />
$('form').live('submit', function() {
$(this).find('input[type="submit"][data-app-disable-on-submit="true"]')
.attr('disabled', 'disabled');
})
;
I set breakpoints on both the remote attribute validation action method and the HttpPost action method. Clicking the submit button the first time hits the breakpoint on the validation action method. At this point, the button is still enabled. I can click it multiple times, and after resuming the validation method, the HttpPost is hit only once. When the HttpPost is hit, the submit button is disabled.
Update
Right you are Alex. So an updated version of the above would look like this:
$('form').on('submit', function() {
$(this).find('input[type="submit"][data-app-disable-on-submit="true"]')
.attr('disabled', 'disabled');
})
$('form').submit(function () {
$('input[type="submit"]', this).attr('disabled', 'disabled');
});
I use a different approach to this. Not wiring to the click event of the button, but to the submit event of the form. Works like a charm to prevent multiple simultaneous submits of forms.
function initFormsToPreventSimultaneousSubmits(selector) {
if (!selector) {
selector = 'form'; // No selector supplied, apply to all forms on the page
}
// Make sure all forms that conform to selector are marked as not submitting
$(selector).each(function()
{
var $form = $(this);
$form.data('submitting', false);
});
// Attach to submit event of all forms that conform to selector
$(selector).off('submit').on('submit', function (e) {
var $form = $(this);
if (!$form.valid || $form.valid()) { // Make sure to only process when the form is valid or jquery validation is not used
if ($form.data('submitting')) {
// form is already submitting. Classic case of double click on one of the submit buttons of the form. Stop the submit
e.preventDefault();
return false;
} else {
// All ok, mark the form as submitting and let the form perform the submit
$form.data('submitting', true);
return true;
}
}
});
}
On document ready i call initFormsToPreventSimultaneousSubmits() to init all forms on the page.
Only thing to remember is that when u use a ajax form post is to call the initFormsToPreventSimultaneousSubmits('#formId') on the OnComplete event of the AjaxOptions settings. Because otherwise the form will still be marked as submitting when its done. When a 'normal' form post is used this is not an issue.
Extends answers by Alex and Ryan P to accounts for situations where jQuery Validation might be missing and where multiple submit buttons exist in a single form.
oneClickSubmitButton = function () {
$('input[type=submit], button[type=submit], input[type=image]').each(function () {
var $theButton = $(this);
var $theForm = $theButton.closest('form');
//hide the button and submit the form
function tieButtonToForm() {
$theButton.one('click', function () {
$theButton.addClass('ui-state-disabled');
});
}
tieButtonToForm();
$theForm.submit(function (event) {
// Only proceed for the clicked button
if (!$theButton.hasClass("ui-state-disabled"))
return;
// If jQuery Validation is not present or the form is valid, the form is valid
if (!$theForm.valid || $theForm.valid())
return;
// Re-wire the event
$theButton.removeClass('ui-state-disabled');
event.preventDefault();
tieButtonToForm();
});
});
};
I was able to fix a similar issue with a couple of lines of code. I prefer this if you don't want to "alert" to user that they double clicked and just silently ignore the second click.
I just made a global javascript variable that I toggled when my function was executing during a critical section. This kept subsequent function calls from re-executing the same section.
var criticalSection = false;
SomeOnClickEventFired = function () {
if (!criticalSection)
{
criticalSection = true;
//Ajax Time
criticalSection = false;
}
}
