How do I have a global variable that is used for only one of two pages
<p>When the user leaves the singup part of the page..the global is no longer needed.</p>

<p>How do I get rid of it..so it does not waste memory?</p>

<p>it is declared in the global namespace as follows:</p>

<pre><code>var local =  
  {  
  client_validation:1, 
  persistent_element:'hide_1' 
  }; 
</code></pre>
