You could use the window.onbeforeunload event
<body onunload="Unloader()">
<script type="text/javascript">
function Unloader() {
}
</script>

App.confirm('popup.cancel.confirmation.message', $('#confirm-import-modal'), true);
return "Do you really want to close?";

i have this problem:
i have this code
if(ext!="rar") {
$('#myform').trigger('click');
}
and if the file extension of the chosen file is not rar, the file input should open the window again to choose another file, but this code does not seem to work. What should i do?
$("#btn").click(function()
{
var fu = $("#fu");
var ext = /[^.]+$/.exec(fu.val());
if (ext!="rar")
{
fu.trigger("click");
}
});

Assuming that your form tag has the id myform, what you have done just triggers a click on the form (not even on the submit button of the form). Without the HTML, it is not possible to know what you are triggering the click on.
What you need to do is trigger the click on the submit button
$('#mysubmitbutton').click();
or trigger a form submit:
$('#myform').submit();

Capturing result of window.onbeforeunload confirmation dialog
I want to make user confirm page navigation like that:
window.onbeforeunload = function(e) {
return "Note that any unsaved data will be lost";
};
however, I want to detect if user clicked "Stay in this page" to do something important.
So is there anyway to detect which button is clicked?
NB: I tried adding confirm in the onbeforeunload function but chrome block it.
There is no way to execute code right after the user decided to stay on the page.
You can use the onunload event to do something in case the user does not stay. If you want to send an AJAX request that's one of the few cases where async: false is appropriate.
Try like this
$(document).ready(function(){
$('body').live('click',function(){
$clicked = (this).attr("value");
alert($clicked);
});
})
Consider that your buttons value should be your message like:"Note that any unsaved data will be lost"

Multiple submit Button click problem?
Have a type=Submit button in a JSP. Requirement is to disable this button on click.
The basic requirement is to stop posting multiple requests of the same form if this button is clicked multiple times for the same form.
Thank You.
Even if you disable the submit button the user can still submit the form by pressing F5 or ctrl+F5 or even using Browser reload button.So disabling the submit button won't be of much use.
Why not use Post/Redirect/Get method.
The PRG pattern basically redirects the user to another page when it is Posted.
Hence now when the user reloads or tries to resubmit the form he is calling the Get method so the form is prevented from resubmission.
However this is also not fully secured approach.
Look here: http://www.developertutorials.com/tutorials/javascript/how-disable-submit-button-050416-1275/
I use a simple JS function you can invoke with onlick():
<script type="text/javascript">
var isSubmitted = false;
function safeSubmit(entityName) {
if (!isSubmitted) {
isSubmitted = true;
document.forms[0].submit;
}
}
</script>
