You don't need to destroy or null variables in Javascript. That already happens when the page changes. — Reinstate Monica Cellio, Oct 02 '16 at 08:11
Yes, You are Right. But I am use localStorage Variable So, not Destroy automatically... manually destroy it. — Kyada Nilesh, Oct 02 '16 at 08:38
So you want to remove data from localStorage when you leave the page? It simply sounds like you should be using variables instead. If this isn't the case then you need to clearly explain what you're trying to do and what the problem is, rather than give us snippets until we finally get to the problem. — Reinstate Monica Cellio, Oct 02 '16 at 08:39

HTTP is stateless, so on every new page the variables will begin in their uninitialised state, and all code set to run on load (ie. not in an event handler) will run.

If you are using localstorage:

Check this question on how to detect changes in the url: How to detect URL changes with jQuery

Then use this to destroy it:

 window.localStorage.removeItem(key);
