Bringing back an "overridden" window method
<p>If I reset window.alert to be some other function, is there any way for me to restore it w/o first "saving" it? </p>

<p>For example:</p>

<pre><code>window.alert = function() { };
</code></pre>

<p>After doing that, is there a way of restoring window.alert() to what it used to be? (btw: asking this only for "predefined" DHTML objects - not for random js objects)</p>
