Dojo Dialog onEnd() animation exception - animation

I have a problem with the Dojo Dijit Dialog .hide() method during the animation sequence. I am using Dojo 1.7 with Tundra theme. I have a cancel button in my dialog that closes the dialog.
var global_welcome = new Dialog({
id: 'global_welcome',
style: "width: 750px",
draggable: false,
content: '<button type="button" id="global_welcomeCancel"> Cancel </button>',
onShow : function () {
on(dojo.byId('global_welcomeCancel'), "click", function (evt) {
dojo.stopEvent(evt);
global_welcome.hide();
});
});
}
});
This produces the following error on Firebug:
exception in animation handler for: onEnd fx.js (line 152)
TypeError: this._fadeOutDeferred is undefined
this._fadeOutDeferred.callback(true);
Previous answers to this error but with destroyRecursive instead of hide suggests it has to do with the dialog being destroyed before the animation finishes. I tried using dojo.hitch() and setTimeOut but that didn't seem to work. Also what is puzzling is that the first time I open this dialog using global_welcome.show() (called by another button), and press the cancel button, it works without error. The second time and afterwards, it produces the above error message. Additionally, the default close button for dojo dialogs on the top right corner never causes this error. Perhaps I could just have onShow call the methods that the close button calls?
Can someone help me out please? Thanks in advance!

The problem is in your onShow method. You wire up to the click event to hide, but never disconnect it. When you open the dialog the again, you wire the click method to hide the dialog again. The result is that hide will be called twice when you try to close the dialog for the second time. The error gets thrown with the second call to hide because the animations have already been destroyed.
Try this:
var signal = on(dojo.byId('global_welcomeCancel'), "click", function (evt) {
dojo.stopEvent(evt);
signal.remove();
global_welcome.hide();
});

Get click handler from element in JQuery

How can I get a reference to the click handler of an element in JQuery?
Here is what I am trying to do:
Store the click handler,
Change the click handler for the next click,
Restore the original click handler
var originalClick = $(settings.currentTarget).click;
$(settings.currentTarget).off("click");
$(settings.currentTarget).click(function (e) {
e.preventDefault();
settings.model.modal.close();
$(settings.currentTarget).off("click");
$(settings.currentTarget).click(originalClick);
});
The above code works the first time, however, when I click on the element again it fails:
Uncaught TypeError: Object [object HTMLAnchorElement] has no method 'on'
Update:
I now realize that this is a really bad design that I am trying to do. I have resolved this issue by maintaining a visibility boolean in my viewmodel, if it is true, don't re-open the modal.
$(...).click is the jQuery click() method, not your event handler.
You can use an undocumented internal API to get the list of event handlers:
jQuery._data( elem, "events" );
What happens if you try it this way?
var originalClick = $(settings.currentTarget).click;
$(settings.currentTarget).off("click");
$(settings.currentTarget).on("click",function (e) {
e.preventDefault();
settings.model.modal.close();
$(settings.currentTarget).off("click");
$(settings.currentTarget).click(originalClick);
});

Slickgrid - Lost focus to end edit

When editing my grid, if I click outside the grid, the box I was editing is still editable. How do I get the edited cell to "complete" the edit when it looses focus?
The following code will save the current edit.
Slick.GlobalEditorLock.commitCurrentEdit();
You'll need to place this inside an event handler that you think should trigger the save. For example, if you're using the sample text editor plugin, I believe an editor-text CSS class is added to the input field that's created when you're editing a cell so something like this should work:
$('#myGrid').on('blur', 'input.editor-text', function() {
Slick.GlobalEditorLock.commitCurrentEdit();
});
I found that I needed to wrap clav's handler in a timeout:
$("#myGrid").on('blur', 'input.editor-text', function() {
window.setTimeout(function() {
if (Slick.GlobalEditorLock.isActive())
Slick.GlobalEditorLock.commitCurrentEdit();
});
});
to avoid errors like:
Uncaught NotFoundError: An attempt was made to reference a Node in a context where it does not exist.
when using the keyboard to navigate. Presumably the new blur handler fires before SlickGrid can do its own handling and this causes problems.
Unfortunately, probably due to differences in event processing, Grame's version breaks keyboard navigation in chrome.
To fix this, I added another check to only commit the edit, if the newly focused element is not another editor element within the grid (as the result of keyboard navigation):
$('#grid').on('blur.editorFocusLost', 'input.editor-text', function() {
window.setTimeout(function() {
var focusedEditor = $("#grid :focus");
if (focusedEditor.length == 0 && Slick.GlobalEditorLock.isActive()) {
Slick.GlobalEditorLock.commitCurrentEdit();
}
});
});
This seems to work in current versions of firefox, chrome and ie.

Ckeditor in jquery dialog not showing up after it is closed

I am trying to open ckeditor in jQuery dialog first time it opens with the ckeditor box perfect I click it again the jQuery dialog loads with textarea with no editor.
I am assuming its because I am not destroying it properly or reinitializing I have no idea Here is a few snippets of what I have tried.
<script type="text/javascript">
if (CKEDITOR.instances['ContentText']) {
CKEDITOR.remove(CKEDITOR.instances['ContentText']);
}
CKEDITOR.replace('ContentText',
{
disableObjectResizing: true,
resize_enabled: false,
shiftEnterMode: CKEDITOR.ENTER_BR,
toolbarCanCollapse: false,
forcePasteAsPlainText: true
});
</script>
<script type="text/javascript">
if (CKEDITOR.instances.ContentText) {
CKEDITOR.instances.ContentText.destroy();
}
CKEDITOR.replace('ContentText',
{
disableObjectResizing: true,
resize_enabled: false,
shiftEnterMode: CKEDITOR.ENTER_BR,
toolbarCanCollapse: false,
forcePasteAsPlainText: true
});
</script>
This is code at the end of the form in the partial view I have tried in the dialog close function in the view
tried editor destroy.. if you want to see the code in action I can deploy it.
What is probably happening is that you're not initializing the CKeditor the second time you open the dialog. The first time it happens on page load. But the second time the modal dialog probably refreshes the dom (html) elements, and these new elements don't have the ckeditor attached to it.
You can solve this by running the initialize code when clicked to open the dialog. Best way is to throw your ckeditor code in a function and add that to the click event that triggers the dialog.
But since you're not posting the code that opens the dialog I could be wrong.
Try using:
CKEDITOR.editor.prototype.destroy
instead of
CKEDITOR.remove
Also you should write a function that is called when the dialog is opened that encompasses your CKE code (both destroying and re-instantiating the the instance).
If both of these things doesn't help you can rename the textarea and call it with the new name you created:
var newCKname = "ContentText" + Math.floor((Math.random()*50)+1);
$('#ContentText').attr('id',newCKname);
[instantiate CKE again with the newCKname]

Scriptaculous Autocomplete list closes on scroll bar click

I have a really annoying issue with Autocomplete with Prototype 1.6. I set up and dialog-style div with a form, which contains an Autocomplete. Everything works fine until I click the scroll bar, or drag it; it closes the list of suggestions. I checked this solution but now I got an javascript error
event.srcElement is undefined
I was checking the controls.js and tried to catch the event object inside the onBlur event, but it travels empty. Printed the offsetX property and is undefined. Looks like the event doesn't exist anymore. either way, it prevents that the list closes but, If I click outside the area, the list now doesn't close. And that's kinda of issue too
Anyone with this same issue? Any idea?
Thanks in advance
I was having the exact issue yesterday, but after doing some r&d I got a pretty handy fix for this.
By default this script was hiding the result div (Suggestion List) on the blur event on the search text box so as soon as we click on result div's scroll bar focus gets lost from input element & result div closes. So I did a small edit in controls.js to change the behavior of script, so now result div close method doesn't invoke on blur (focus out) from input element but triggered on the click on the document except the text input element.
For your convenience I've put the edited controls.js here.
If you like to know what has changed in JS file, here it is;
Added a event listener to the document. Just below this line
"Event.observe(this.update, "keypress", this.onKeyPress.bindAsEventListener(this));"
Event.observe($(document), "mouseup", this.onMouseup.bindAsEventListener(this));
Added a new onMouseup method.
onMouseup: function(event) {
if(!this.hasFocus) {
this.hideTimeout = setTimeout(this.hide.bind(this), 250);
this.hasFocus = false;
this.active = false;
}
},
Modify the onBlur method (Comment out two line in block)
onBlur: function(event) {
//this.hideTimeout = setTimeout(this.hide.bind(this), 250);
//this.active = false;
this.hasFocus = false;
}
I hope this will solve your issue.

backbone.js click and blur events

I'm having some trouble with blur and click events in backbone. I have a view (code below) that creates a little search entry div with a button. I pop open this div and put focus on the entry field. If someone clicks off (blur) I notify a parent view to close this one. If they click on the button I'll initiate a search.
The blur behavior works fine, however when I click on the button I also get a blur event and can't get the click event. Have I got this structured right?
BTW, some other posts have suggested things like adding timers to the div in case its being closed before the click event fires. I can comment out the close completely and still only get the blur event. Do these only fire one at a time on some kind of first-com-first-served basis?
PB_SearchEntryView = Backbone.View.extend({
template: _.template("<div id='searchEntry' class='searchEntry'><input id='part'></input><button id='findit'>Search</button></div>"),
events: {
"click button": "find",
"blur #part": "close"
},
initialize: function(args) {
this.dad = args.dad;
},
render: function(){
$(this.el).html(this.template());
return this;
},
close: function(event){ this.dad.close(); },
find: function() {
alert("Find!");
}
});
I am not sure what the problem was, but here is the jsbin code.
