Change event function parameters with JQuery
<p>I have an image map that contains certain "Areas" that contain onmouseover events. Most of these events fire a function which passes in some coordinates. 
I want to be able to manipulate the coords in the function SFX_ShowIconOver.</p>

<p>The Image Map is created by a third party app so I can only manipulate rendered content.</p>

<pre><code>&lt;AREA onmouseover="SFX_ShowIconOver('Chart2','29456',368,10,22,22,false,this)" title="Legend Box" onclick="SFX_SendCommand('29456',false)" shape=rect coords=368,10,390,32&gt;
</code></pre>
