Jquery Conflict for back button code snippet

upgraded from 1.4 to v=1.7

Here i am placing couple of request.

  1. jquery snippet conflict

  2. Back button snippet

TypeError: $j(...).on is not a function

How popup alert when someone clicked the back button, below is the code but looks not working, still i have one more issue that is conflict, can you some one suggest the best way to resolve this issue.

jQuery(function () {
if (window.history && window.history.pushState) {
window.history.pushState('', null, './');
jQuery(window).on('popstate', function () {
alert('Back button was pressed.');


From the documentation for on:

version added: 1.7

You must be using an older version of jQuery. Upgrade to a current version.
