How to disable back button in browser using javascript

Here is the javascript code that will help you disable back button in your web browser.

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">
function noBack() { window.history.forward(); }
<BODY onload="noBack();"
onpageshow="if (event.persisted) noBack();" onunload="">
