How do I generate a random number within my javascript code?
<p>I'm using some 3rd party javascript to generate a slideshows within each of the posts on a blog.  Each slideshow must have a unique ID to work properly.  I figured the easiest way to do this would be to generate a large random number for each slideshow when it's loaded on the page.</p>

<p>Below is a snippet of the relevant parts of the code where POSTID represents the random number.  Note that the same random number must be referenced in the div below the script.</p>

<pre><code>&lt;script language="javascript" type="text/javascript"&gt;
        $(function() {
        $("#POSTID").webwidget_slideshow_dot({
        slideshow_time_interval: '',
        slideshow_window_width: '320',
        slideshow_window_height: '480',
        slideshow_title_color: '#17CCCC',
        soldeshow_foreColor: '#000',
        });
        });
&lt;/script&gt;

&lt;div id="POSTID" class="webwidget_slideshow_dot"&gt;
        &lt;!-- some content goes here --&gt;
&lt;/div&gt;
</code></pre>

<p>Any help would be greatly appreciated!</p>

<p>Thanks</p>
