Pass variable to external javascript?
<p>I have a plugin which shows posts from a certain city:</p>

<pre><code>&lt;div id='banner-root' style="height: 50px; width: 385px;"&gt;&lt;/div&gt;
&lt;script src="http://lujanventas.com/plugins/banner.js" type="text/javascript"&gt;&lt;/script&gt;
</code></pre>

<p>I need to pass the cityID to the external javascript. I'm already getting height and width on the external .js by simply checking the banner-root element.</p>

<p>How do I pass the and ID? Also it would be nice if it was clear that you are passing the cityID</p>
