Using Ajax and trying to create a popstate event handler on the actual Ajax page using the .document object:
document.addEventListener("popstate", myPopState);
Unfortunately this does not ever seem to trigger.
My intention being that after the page is reloaded the popstate event trigger will automatically disappear.
inside ajax success response , you could use
var msg="Any thing which u want";
var customUrl ="www.stackoverflow.com";
window.history.pushState({"html":msg,"pageTitle":"My Title"},"", customUrl);
window.onpopstate = function(event) {
alert('back is clicked');
// what ever u want
}
UPDATE
$(window).unload(function(e){
e.preventDefault();
$(window).trigger('beforeunload');
});
$(window).bind('beforeunload',function(){
alert('call your ajax here');
return '';
});
