unbinding a function after called once in jquery

Question

I have a function in jquery called navigation which is called once the page is loaded.

$(document).ready(function(){
   navigation();
 });

the function definition is global. This function is again called on an ajax success function

var onSuccess=function(data){
    //unbind the previous navigation
   navigation();
  }

How do i unbind the previous navigation function so that the call on onSuccess is a new call

You can't "unbind" a function call, the real question is what `navigation()` does that needs to be unbound. — Fabrício Matté, Jul 08 '13 at 06:50
on clicking forward button or backward button it takes uto next page or previous page — user2525513, Jul 08 '13 at 07:10
If I'm not mistaken, loading another page (not just exchanging page content) would void any defined functions anyway? — mabi, Jul 08 '13 at 07:15

For what you're asking deleting a global property and specifically the link given there: http://perfectionkills.com/understanding-delete/ will help you understand why what you want is not possible (or really akward, you need to read the linked text for the full story).

That makes me agree with @FabrícioMatté - you really, really want to rework your navigation function to keep track of what it loaded so you can just call it again and have it work out where to go next. There's no reason I can think of to redefine the function.
