There are times while developing a website, we need to disable back button in browser. Most common example of this is found in Online Banking Websites.
Most of the time the back button is disabled because a user can hit back and navigate from the page and forget to logout.
Given below code in Java script that will disable the working of Back button in Browser:
<SCRIPT type="text/javascript">
window.history.forward();
function noBack() { window.history.forward(); }
</SCRIPT>
</HEAD>
<BODY onload="noBack();"
onpageshow="if (event.persisted) noBack();" onunload="">
Note: If you want to stop user navigating back from Page 2 to Page 1 then the code here is placed in the head section of Page 1.
