How to setup javascript redirect to send user to back page? see code

Question

With onclick="history.go(-1);return false;" user can navigate to back pages. But if I want to put a confirm method before it takes user to the back. How would I do that?

I think it can be achieved by doing something like below but I am not sure how to redirect user to back page?

$('.clickme').click(function() {     if(confirm("Are you sure you want to navigate away from this page?"))     {       //window.close();       // how to redirect to history.go(-1) ??     }             return false;  }); 

UPDATE

Also is there any way I can check if history has some values in it or is empty? So that I can alert user if is empty?

Answer 1

It's quite as simple as you think it is:

$('.clickme').click(function() {    if(confirm("Are you sure you want to navigate away from this page?"))    {       history.go(-1);    }            return false; }); 

Answer 2

Try this:

    if(confirm("Are you sure you want to navigate away from this page?"))     {       history.back();     }
