Sending click event to parent anchor
<p>How do I send a click event (JS or JQuery) to a parent object that is an anchor?  My basic HTML looks like:</p>

<pre><code>&lt;a href="javascript:myFunc(1,2,3)"&gt;
  &lt;img id="btn1" src="myimg.png"&gt;
&lt;/a&gt;
</code></pre>

<p>So I can easily reference the anchor through button via: </p>

<pre><code>document.getElementById('btn1').parentNode
</code></pre>

<p>However, </p>

<pre><code>document.getElementById('btn1').parentNode.click
</code></pre>

<p>while it doesn't seem to raise an error in the console on firebug, the javascript function doesn't seem to be firing either.  How do I send a click to this thing.  By the way, I don't have control of the HTML so I can't just ad an ID to the anchor tag.</p>
