JavaScript - Backtracking code?
<p>I'm just opened FireBug and saw this on my site</p>

<pre><code>&lt;div style="display: none; width: 0px; height: 0px; overflow: hidden;"&gt;
    &lt;iframe src="javascript:void(0)" style="display: none;"&gt;&lt;/iframe&gt;
    &lt;iframe src="javascript:void(0)" style="display: none;"&gt;&lt;/iframe&gt;
    &lt;iframe src="javascript:void(0)" style="display: none;"&gt;&lt;/iframe&gt;
    &lt;iframe src="javascript:void(0)" style="display: none;"&gt;&lt;/iframe&gt;
    &lt;iframe src="javascript:void(0)" style="display: none;"&gt;&lt;/iframe&gt;
    &lt;iframe src="javascript:void(0)" style="display: none;"&gt;&lt;/iframe&gt;
    &lt;iframe src="javascript:void(0)" style="display: none;"&gt;&lt;/iframe&gt;
    &lt;iframe src="javascript:void(0)" style="display: none;"&gt;&lt;/iframe&gt;
    &lt;iframe src="javascript:void(0)" style="display: none;"&gt;&lt;/iframe&gt;
    &lt;iframe src="javascript:void(0)" style="display: none;"&gt;&lt;/iframe&gt;
&lt;/div&gt;
</code></pre>

<p>Is there a way to backtrack this code and see where it originated from as it's not hardcoded?</p>
