I am using jquery-1.4.4 in struts. I had successfully used the jquery.validate plugin and validated my request form. But since it is a 3 page form, I have to give a confirm dialog box at each page to ensure users recheck their form entries.
$(document).ready(function() {
:::
$("#Form1").validate({
::
});
function onSubmitForm(){
var vconf = confirm(" You are about to submit, please recheck the the fields");
if(vconf){
return true;
}else{
return false;
}
}
});
and my submit button
<input type="submit" title="continue filling up the form" value=" Continue "
onclick= "return onSubmitForm();"/>
This first calls my confirm dialog and then does validation, which is not appropriate to first ask the user if he actually wants to continue and then stop them saying that their form is not valid.
i think so you can try this....
<script type="text/javascript">
$(document).ready(function() {
$("#Form1").validate({
submitHandler : function(form) {
if (confirm("You are about to submit, please recheck the the fields?")) {
form.submit();
}
},
rules: {
x: {
required: true,
},
y:{
required:true,
}
}
})
});
</script>
perhaps this should help you. Jquery validate onValid.
Just call the function onSubmitForm() after you submit, and submit the form using javascript.

I have a form in which I need to call two action methods, one after the other. This is how the flow goes.
First I check if the prerequisite data is entered by the user. If not then I show a message that user needs to enter the data first.
If all the prerequisite data is entered, I call an action method which return data. If there is no data returned then I show a message "No data found" on the same page.
If data is returned then I call another action method present in a different controller, which returns a view with all the data, in a new tab.
The View:
#using (Ajax.BeginForm("Index", "OrderListItems", null, new AjaxOptions { OnBegin = "verifyRequiredData"}, new { #id = "formCreateOrderListReport", #target = "_blank" }))
{
//Contains controls and a button
}
The Script in this View:
function verifyRequiredData() {
if ($("#dtScheduledDate").val() == "") {
$('#dvValidationSummary').html("");
var errorMessage = "";
errorMessage = "<span>Please correct the following errors:</span><ul>";
errorMessage += "<li>Please enter Scheduled date</li>";
$('#dvValidationSummary').append(errorMessage);
$('#dvValidationSummary').removeClass('validation-summary-valid').addClass('validation-summary-errors');
return false;
}
else {
$('#dvValidationSummary').addClass('validation-summary-valid').removeClass('validation-summary-errors');
$('#dvValidationSummary').html("");
$.ajax({
type: "GET",
url: '#Url.Action("GetOrderListReport", "OrderList")',
data: {
ScheduledDate: $("#dtScheduledDate").val(),
Crews: $('#selAddCrewMembers').val(),
Priorities: $('#selPriority').val(),
ServiceTypes: $('#selServiceTypes').val(),
IsMeterInfoRequired: $('#chkPrintMeterInfo').val()
},
cache: false,
success: function (data) {
debugger;
if (data !== "No data found") {
//var newUrl = '#Url.Action("Index", "OrderListItems")';
//window.open(newUrl, '_blank');
return true;
} else {
//Show message "No data found"
return false;
}
}
});
return false;
}
}
The "GetOrderListReport" Action method in "OrderList" Controller:
public ActionResult GetOrderListReport(OrderListModel model)
{
var contract = new OrderReportDrilldownParamDataContract
{
ScheduledDate = model.ScheduledDate
//Setting other properties as well
};
var result = OrderDataModel.GetOrderList(contract);
if (string.IsNullOrWhiteSpace(result) || string.IsNullOrEmpty(result))
{
return Json("No data found", JsonRequestBehavior.AllowGet);
}
var deserializedData = SO.Core.ExtensionMethods.DeserializeObjectFromJson<OrderReportDrilldownDataContract>(result);
// send it to index method for list
TempData["DataContract"] = deserializedData;
return Json(deserializedData, JsonRequestBehavior.AllowGet);
}
The last action method present in OrderListItems Controller, the result of which needs to be shown in a new tab:
public ActionResult Index()
{
var deserializedData = TempData["DataContract"] as OrderReportDrilldownDataContract;
var model = new OrderListItemViewModel(deserializedData);
return View(model);
}
The problem is that I am not seeing this data in a new tab, although I have used #target = "_blank" in the Ajax.BeginForm. I have also tried to use window.open(newUrl, '_blank') as can be seen above. But still the result is not shown in a new tab.
Please assist as to where I am going wrong?
If you are using the Ajax.BeginForm you shouldn't also be doing an ajax post, as the unobtrusive ajax library will automatically perform an ajax post when submitting the form.
Also, if you use a view model with data annotation validations and client unobtrusive validations, then there would be no need for you to manually validate the data in the begin ajax callback as the form won't be submitted if any validation errors are found.
The only javascript code you need to add in this scenario is a piece of code for the ajax success callback. That will look as the one you currently have, but you need to take into account that opening in new tabs depends on the browser and user settings. It may even be considered as a pop-up by the browser and blocked, requiring the user intervention to allow them as in IE8. You can give it a try on this fiddle.
So this would be your model:
public class OrderListModel
{
[Required]
public DateTime ScheduledDate { get; set; }
//the other properties of the OrderListModel
}
The form will be posted using unobtrusive Ajax to the GetOrderListReport of the OrderList controller. On the sucess callback you will check for the response and when it is different from "No data found", you will then manually open the OrderListItems page on a new tab.
This would be your view:
#model someNamespace.OrderListModel
<script type="text/javascript">
function ViewOrderListItems(data){
debugger;
if (data !== "No data found") {
var newUrl = '#Url.Action("Index", "OrderListItems")';
//this will work or not depending on browser and user settings.
//passing _newtab may work in Firefox too.
window.open(newUrl, '_blank');
} else {
//Show message "No data found" somewhere in the current page
}
}
</script>
#using (Ajax.BeginForm("GetOrderListReport", "OrderList", null,
new AjaxOptions { OnSucces= "ViewOrderListItems"},
new { #id = "formCreateOrderListReport" }))
{
#Html.ValidationSummary(false)
//input and submit buttons
//for inputs, make sure to use the helpers like #Html.TextBoxFor(), #Html.CheckBoxFor(), etc
//so the unobtrusive validation attributes are added to your input elements.
//You may consider using #Html.ValidationMessageFor() so error messages are displayed next to the inputs instead in the validation summary
//Example:
<div>
#Html.LabelFor(m => m.ScheduledDate)
</div>
<div>
#Html.TextBoxFor(m => m.ScheduledDate, new {id = "dtScheduledDate"})
#Html.ValidationMessageFor(m => m.ScheduledDate)
</div>
<input type="submit" value="Get Report" />
}
With this in place, you should be able to post the data in the initial page using ajax. Then based on the response received you will open another window\tab (as mentioned, depending on browser and user settings this may be opened in a new window or even be blocked) with the second page content (OrderListItems).
Here's a skeleton of what I think you are trying to do. Note that window.open is a popup though and most user will have popups blocked.
<form id="formCreateOrderListReport">
<input type="text" vaule="testing" name="id" id="id"/>
<input type="submit" value="submit" />
</form>
<script type="text/javascript">
$('#formCreateOrderListReport').on('submit', function (event) {
$.ajax({
type: "POST",
url: '/home/test',
data: { id: $('#id').val()},
cache: false
}).done(function () {
debugger;
alert("success");
var newUrl = '/home/contact';
window.open(newUrl, '_blank');
}).fail(function () {
debugger;
alert("error");
});
return false;
});
</script>
Scale down the app to get the UI flow that you want then work with data.
I have an strongly typed view for my model and what I'd like is that when the user clicks on submit, a confirmation box pop up confirming that the user does indeed wish to submit the form, if they click cancel then it shouldn't fire the HttpPost Action for that View, is this possible?
Of course it is possible. I like to use an unobtrusive approach. Here is a simplified example:
jQuery(document).ready(function () {
jQuery('[data-confirm]').click(function (e) {
if (!confirm(jQuery(this).attr("data-confirm")))
{
e.preventDefault();
}
});
});
Then you only need to add a data-confirm attribute to your submit button for example
<input type="submit" data-confirm="are u sure?" />
Of course you can use this attribute on links, buttons, etc. you are not restricted to submit buttons only, and if you want to implement a fancier confirm dialog later than you will have to replace the code only in one place.
function doSubmit()
{
if(window.confirm("ARE YOU SURE TO PERFORM THIS ACTION"))
{
return true;
}
else return false;
}
call doSubmit() function on onsubmit event of the form,
Eg- onsubmit="return doSubmit()
you can add a simply jQuery call for that.
at the end of your view add:
<script type="text/javascript">
$("form").submit(function() {
return confirm('Are you sure?');
});
</script>
or, add a
onsubmit="return confirm('Are you sure?');"
as a new element property
I believe this can be done by overriding the submit button using jquery. Jquery .submit()
This way, when the person hits submit you can show a message and either submit it or cancel it.
I have a form + layout like so:
<form ...>
<div id="editor">
[form html]
<input type="submit" value="Submit form" />
</div>
</form>
And the following javascript:
$(function() {
var form = $('#editor').parents('form');
alert(form.length); // this alerts "1"
$(document).on('submit', 'form', function() {
alert('document form submit fired'); // this works as expected (alerts)
});
form.on('submit', function() {
alert('selected form submit fired'); // this is never alerted
});
});
This form is not loaded via ajax. When the page loads, the first dialog alerts "1". However when submitting the form, only one alert is fired -- the one that triggers submit for all forms in the document.
Why would this happen?
It does work. Something else is happening which is preventing the second alert from firing.
Your form selector is incorrect.
Try and do this
$("form").on('submit', function() {
Pretty sure this should work
Actually if nothing is being loaded through ajax or dynamically through javascript
You can just do
$("form").submit(function() {
EDIT
Scratch my above. Didn't see you set the value of form. Check out http://jsfiddle.net/s3fvM/1/. Seems to be working fine to me. both are firing and alerting.
I am rendering a form in Asp.net MVC with a submit button. The page redirects after successful record addition into the database. Following is the code :-
[HttpPost]
public ActionResult Create(BrandPicView brandPic)
{
if (ModelState.IsValid)
{
if (!String.IsNullOrEmpty(brandPic.Picture.PictureUrl))
{
Picture picture = new Picture();
picture.PictureUrl = brandPic.Picture.PictureUrl;
db.Pictures.Add(picture);
brandPic.Brand.PictureId = picture.Id;
}
db.Brands.Add(brandPic.Brand);
db.SaveChanges();
return RedirectToAction("Index");
}
return View();
}
But, while testing, I saw that if the form is clicked again and again, the multiple entries are submitted and saved into the database.
How can i make sure that if the form has been submitted once to the server, then no duplicates are submitted.
I don't think this is quite a duplicate of the answer referenced in the comment, since the link is for spring MVC, and this question is for .NET MVC.
I actually spent a few hours on this a while back, and came up with the following. This javascript hooks nicely with the unobtrusive jquery validation, and you can apply it to any form that has <input type="submit". Note that it uses jquery 1.7's on function:
$(document).on('invalid-form.validate', 'form', function () {
var button = $(this).find(':submit');
setTimeout(function () {
button.removeAttr('disabled');
}, 1);
});
$(document).on('submit', 'form', function () {
var button = $(this).find(':submit');
setTimeout(function () {
button.attr('disabled', 'disabled');
}, 0);
});
The setTimeouts are needed. Otherwise, you could end up with a button that is disabled after clicked even when client-side validation fails. We have this in a global javascript file so that it is automatically applied to all of our forms.
Update 16 Nov 2020 by #seagull :
Replaced selector input[type="submit"] with :submit so it will work with <button type="submit" /> as well
The solution for mvc applications with mvc client side validation should be:
$('form').submit(function () {
if ($(this).valid()) {
$(':submit', this).attr('disabled', 'disabled');
}
});
Disable the button on Submit clicked. This can be done using JQuery/Java Script.
Look at this example on how to do this.
You can use this one. It includes unobtrusive jQuery validation.
$(document).on('submit', 'form', function () {
var buttons = $(this).find('[type="submit"]');
if ($(this).valid()) {
buttons.each(function (btn) {
$(buttons[btn]).prop('disabled', true);
});
} else {
buttons.each(function (btn) {
$(buttons[btn]).prop('disabled', false);
});
} });
For jQuery validation please incllude
~/Scripts/jquery.validate.min.js
~/Scripts/jquery.validate.unobtrusive.min.js
You can use ajax.BeginForm insted of html.BeginForm to achieve this, if you use OnSuccess insted of OnBegin you can be sure that your method execute successful and after that your button turn to deactivate,with ajax you stay
in current view and you can update your current view instead of redirection
#using (Ajax.BeginForm(
new AjaxOptions
{
HttpMethod = "post",
InsertionMode = InsertionMode.Replace,
UpdateTargetId = "dive",
OnBegin="deactive"
}))
{
//body of your form same as Html.BeginForm
<input type="submit" id="Submit" value="Submit" />
}
and use this jquery in your form:
<script type="text/javascript" language="javascript"> function deactive() { $("#Submit").attr("disabled", true); }</script>
be careful for using ajax you have to call this scrip in the end of your page
<script src="~/Scripts/jquery.unobtrusive-ajax.js"></script>
Disabling the button is fine via JavaScript but what if the user has it disabled or they bypass it? If you use client side security then back it up with server side. I would use the PRG pattern here.
window.onload = function () {
$("#formId").submit(function() {// prevent the submit button to be pressed twice
$(this).find('#submitBtnId').attr('disabled', true);
$(this).find('#submitBtnId').text('Sending, please wait');
});
}
I have a save button (input button) that I have written javascript code to save the form data to the database. My jQuery .validate function doesn't run before I save the form. How can I manually execute my jQuery .validate function before I save. Here is what I am doing.
<input type="button" class="saveSubmit" name="action" value="Save" />
// Give user feedback when clicking save
$(".saveSubmit").click(function() {
if (save() == true) {
alert("Email has been saved.");
} else {
alert("Error saving email.");
};
return false;
});
// Validation
$("#emailForm").validate({
// rules here
});
Found it. I need to use $("#emailForm").valid().
