Question

I want to detect browser back button in java-script/jquery without using any external plugins.

I am going to support following browsers

Answer 1

That can be simply dropped into your web page, and when the user clicks back, it will call a function. The default function on this call is a javascript alert “Back Button Clicked”.

To replace this functionality, you simply need to override the OnBack function. This can be done by using the code below.

This will now replace the “Back Button Clicked” alert with a “You clicked it!’” alert.
