How can I call a javascript or jQuery function when back button of browser is clicked? I have seen some solutions but none of them worked for me. Can anybody show me some example code?

Answer 1

In jQuery try this :

$(window).unload( function () 
{
// put your code here
});

In javascript :

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