Jquery ui dialog not closing with `Escape` keypress

When a user opens dialog, there are a bunch of ajax requests that have to be processed and therefore i have a second dialog that just displays loading information and closes once all the requests have been processed.
I am not able to close the user opened dialog with Escape key once it has opened. I have to click on the the dialog itself before I can use escape.
I have tried the following to assign the user opened dialog the focus after the loading dialog closes but to no avail, I still have to click on the dialog before it can close with the escape key.
$(document).ajaxStart(function () {
// IF loading dialog is not allready being shown show it.
if ($("#LoadingData").dialog('isOpen') === false) {
$("#LoadingData").dialog('open');
}
});
$(document).ajaxStop(function () {
//Close the loading dialog once the requests have finished
$("#LoadingData").dialog('close');
//Find the user opened dialog
$('.cmdialog').each(function () {
if ($(this).dialog('isOpen')) {
$(this).trigger('click');//set focus to dialog
// have also replaced .trigger('click') with .focus() but to no avail
}
}).on('click', function() {
//if click is triggerd set the focus of the dialog.
if ($(this).prop('id') != 'LoadingData') {
$(this).focus();
}
});
});
I have also tried setting the focus to the first element within the dialog with $('#DialogName:first-child').focus() and $('#DialogName:first-child').trigger('click') but this is also not working.
Any ideas as to why the focus is not set? Or am I misunderstanding/incorrectly using .focus() and .trigger('event')?
Thanks :)

Try the below code for close the dialog when Escap key is pressed:
$(document).keyup(function(e) {
if (e.keyCode == 27) { $("#LoadingData").dialog('close'); } // esc
});

I had the same issue, and found pretty elegant solution, in case you want to close dialog before actually clicking inside it:
$("#LoadingData").dialog({
...,
focus: function () {
$('#LoadingData').closest('.ui-dialog').focus();
}
});
So, we just need to set focus to parent .ui-dialog container, and in that case Esc will work for all cases. Disadvantage of $(document).keyup solution, if you have nested dialogs, Esc button will close your most top dialog and bottom one too.

the focus event is sent to an element when it gains focus. This event is implicitly applicable to a limited set of elements, such as form elements (, , etc.) and links. docs here
You can try moveToTop method of the dialog, maybe it will help
And in your code, I think, you should bind "click" event before triggering it.

The following code should work even for multiple modals open:
$(document).on('keydown','.modal-dialog',function(event){
if (event.keyCode == 27) {
$(this).closest('.modal-dialog').find('[data-dismiss="modal"]').click();
}
});

Any way to know if the click is coming from a "trigger" or actual click?

I have a curious situation. I am editing a page that is a gazzilion moving parts.
Anyways, I have a dialog box (popup) that is bound (via the dialog creation class) to a body click handler. Basically, if you click anywhere on the page, it closes. Ok, great.
Here is the rub. There is another process on the page that runs that "$(body).trigger('click')". This is creating an issue, because in THIS situation, I do not want my particular dialog to close.
I ran some tests and they appear to be identical --
1.) generating a click via a trigger
2.) and actually clicking on the body of the page.
Is there any discernible way to know if a click is a "fake" trigger call or real 'click' event? Since nothing is bubbling in a triggered click, is there anyways to somehow try to see if there is a child elem on the page to see if its bubbling or something?
I hope I am succinct enough in my explanation.

HTML:
<input type="button" id="button" value="click me" />
JS:
$("#button").on("click", function(e) {
if(typeof e.isTrigger == 'undefined') {
console.log("clicked");
} else {
console.log("triggered");
}
});
setTimeout(function() {
$("#button").trigger("click");
}, 1000);
Demo: http://jsfiddle.net/wXnwp/1/
A version for jQuery 1.6 => http://jsfiddle.net/wXnwp/3/
$("#button").click(function(e) {
if(typeof e.ctrlKey !== 'undefined') {
console.log("clicked");
} else {
console.log("triggered");
}
});
setTimeout(function() {
$("#button").trigger("click");
}, 1000);

onclick event not firing after onchange event

Does anyone know how to make a simple JavaScript onclick event fire if the process of clicking the element causes an onchange event to fire elsewhere on the page? I've created a very simple page to demonstrate this problem:
<html>
<body>
<input type="text" name="test" id="test1" onchange="return change(event);" />
Bang
Boom
<script type="text/javascript">
function change(event) {
alert("Change");
return true;
}
function bang() {
alert("Bang!");
return true;
}
function boom() {
alert("Boom!");
return true;
}
</script>
</body>
</html>
If you click the bang link you get the Bang! alert. Boom gives you the Boom alert. And if you enter text in the text field and tab out you get the Change alert. All well and good.
However, if you enter text in the text field and, without tabbing or clicking anything else first, click either Bang or Boom you get the Change alert and nothing else. I would expect to see the Change alert followed by either Bang or Boom.
What's going on here? My change event returns true. How can I ensure that my click event is fired?

Okay... So it seems like it's time for a bit of an explanation.
Explanation
You encounter this error because the onchange event is triggered as soon as focus is moved away from the element. In your example the action that takes focuse away from the input element is the mousedown event which triggers as you click down on the mouse. This means that when you mousedown on the link it fires off the onchange function and pops up the alert.
The onclick event on the other hand is triggered on the mouseup event (i.e. when you release the pressure on the mouse - prove this to yourself by click, hold/pause, release on a onlcick event). Back to your situation... Before the mouseup (i.e. onclick) happens the focus is moved to the alert triggered from your onchange function.
Fix
There are a couple of options to fix this. Most simple change from using onclick="...." to onmousedown="....".
Alternatively, you could use setTimeout like,:
function change() {
setTimeout(function (){
alert("Change event")
}, 100)
}
I suggest the onmousedown method as preferred. The setTimeout method will fail if you click and hold on the link for more than the prescribed amount on the timeout.

The problem is that the alert() function grabs the event chain somehow, test this:
<html>
<body>
<input type="text" name="test" id="test1" onchange="return change(event);" />
Bang Boom
<script type="text/javascript">
function change(event) {
console.log("change");
return true;
}
function bang() {
console.log("bang");
return true;
}
function boom() {
console.log("boom");
return true;
}
</script>
</body>
As you'll see you'll get the expected behaviour in the console.
JSBin

Rather than try and replicate your problem, I just created the solution in jsFiddle.
I seperated your HTML and your JavaScript.
HTML
<input type="text" name="test1" id="test1" />
Bang
Boom
JavaScript
var test1 = document.getElementById("test1");
var test2 = document.getElementById("test2");
var test3 = document.getElementById("test3");
test1.onchange = function (event) {
alert("Change");
};
test2.onclick = function () {
alert("Bang!");
};
test3.onclick = function () {
alert("Boom!");
};
After making a change in the text box and click out side of it will trigger the onchange event, and the onclick events will still fire. If you are expecting the change alert to fire for each key stroke change onchange to onkeyup.

Close colorbox popup with a button and trigger the confirm box?

I have a confirm box on my colorbox("are you sure you want to leave?").
This triggers when i close the popup. This works when i click on the "cboxClose" div on the popup.
I am trying to show this confirm box on a button click. But the popup just closes right away without showing the confirm box.
My question is how do i trigger the the confirm box when i click on a cancel button. i tried several ways
//This just closes the pop up without showing the confirm box
$('#btnCancel').click(function () {
parent.$.colorbox.close(); });
//doesn't work
$('#btnCancel').click(function () {
$('#cboxClose').click()
});
COLORBOX
onComplete: function () {
$("#cboxClose").click(function (e) {
// stop any other script from firing
e.stopPropagation();
if (confirm('are you sure you want to leave?')) {
$.colorbox.close();
// ensure that the binding is removed when closed
$("#cboxClose").unbind();
}
});
} // close oncomplete

The issue here is that colorbox registers a click handler on the cboxClose element. As a result, neither stopping bubbling nor preventing the click (by returning false in a click handler) will have any effect because the colorbox handler is already registered. The only way of stopping that handler from being run is to unbind it. However, to do that you need a reference to the handler, which you won't get without modifying the colorbox code.
In any case, that's what's going on and why the code you have above doesn't work. Another option for you would be to override the colorbox close function (which is the public colorbox method that is called by colorbox's close button handler). All you need is this:
$.colorbox._close = $.colorbox.close;
$.colorbox.close = function() {
if(confirm("Close?")) {
$.colorbox._close();
}
}
The down side (which may not be an issue in your situation) is that this will affect all colorboxes on the page.

I solved this issue by making this method and binding it to the cancel button
var originalClose = $.colorbox.close;
$.colorbox.close = function (e) {
var response;
var formChanged = localStorage.getItem("isFormChanged");
var saveClicked = localStorage.getItem("saveClicked");
if (formChanged == "true" && saveClicked == "false") {
response = confirm('Do you want to close this window? All your changes will not be saved');
if (!response) {
return
}
}
originalClose();
};
<input type="button" value="Cancel" id="btncancel" onclick="parent.$.colorbox.close()"/>

Button onclick doesn't fire after onchange input-field when user immediately clicks the button

I have an input text with an onchange event that calls a function in which an alert box displays. I also have a button whose onclick calls a different function. If the user makes a change in the input text and immediately clicks the button, the onchange event fires, displaying the alert box, but the code in the function for the onclick of the button doesn't execute. I've read that this has something to do with event bubbling, but I haven't seen any solutions. Is there a solution? Is it even possible?
Here is a little example:
<input type = "text" onchange = "showAlert1()">
<input type = "button" id = "al2" value = "Click Here" onclick = "showAlert2()">
<script type = "text/javascript">
function showAlert1()
{
alert("ONE")
}
function showAlert2()
{
alert ("TWO");
}
</script>
The onclick event handler showAlert2() doesn't fire if a change is made to the input value and user immediately clicks the button.
I want, that you write something to the input-field, click IMMEDIATELY the button and it fires
alert("ONE") AND alert("TWO")...
OR ONLY
alert("TWO")

As far as I can tell it's not a problem with bubbling (which is a problem with onchange but is a red herring in this case). The problem is that clicking the button after changing the field value is triggering blur, causing showAlert1() to run before the button's onclick gets triggered.
Here's a quick example of it working the way you described but you'll see it's an unreliable hack more than anything. Basically it buffers the execution of each function so that the button's onclick can be triggered. However it falls over if you click and hold the button longer than the buffer that is set within each function via setTimeout().
function showAlert1() {
setTimeout(function(){ alert("ONE") }, 250);
}
function showAlert2() {
setTimeout(function(){ alert("TWO") }, 250);
}
Demo: jsfiddle.net/5rTLq

how about this
function showAlert1(a) {
alert(a.value); /* use setTimeout to delay */
}
function showAlert2() {
alert(document.getElementById('txt').value);
}
