Can we detect browsers refresh and back button events?

Question

Anybody know how to detect browsers refresh and back button events in firefox using jquery or javascript.

Answer 1

For back button:

window.addEventListener('popstate', function (event) {
//Your code here
});

For Refresh:

window.onbeforeunload = function () {
 // Your code here
}

Answer 2

You can try WindowEventHandlers.onbeforeunload:

window.onbeforeunload = function(e) {

};

and

$(window).unload(function() {
      //
});

Also check Browser Back Button Detection:

I have made a very reusable javascript class, that can be simply dropped into your web page, and when the user clicks back, it will call a function. The default function on this call is a javascript alert “Back Button Clicked”.

To replace this functionality, you simply need to override the OnBack function. This can be done by using the code below.

<script type="text/javascript">
bajb_backdetect.OnBack = function()
{
alert('You clicked it!');
}
</script>

This will now replace the “Back Button Clicked” alert with a “You clicked it!’” alert.
