Hello everyone,
I want to pop up a message asking for confirmation if the user wants to leave the current page, exactly like stackoverflow does it when you are typing a question.
Could someone help me on this, by giving me a script or redirecting me to an answer (on this site or elsewhere) ?
Thanks
You could use the onbeforeunload event.
window.onbeforeunload = function() {
return 'Are you sure that you want to leave this page?';
}
You need to handle the window's onbeforeunload event and return a confirmation message as a string.
onunload will not work here. DemoDoesn't this work?
<body onunload="return confirm('really quit?');">
Also for framesets by the way...
window.onbeforeunload Seems to work for IE, but something like
window.onunload = function()
{
if (confirm('Save changes?'))
document.forms['form1'].submit();
};
Seems to work for all browsers.
You will have to store all the values of your fields in some variables & check them whenever use changes the page url or clicks on some link, to trap the page change event use page unload event.
