How javascript gets someother website data?
<p>Well i am a bit confused..</p>

<p>I saw a service known as Zopim.. What they do is they provide you with a small piece of code:</p>

<p>such as </p>

<pre><code>&lt;!-- Start of Zopim Live Chat Script --&gt; 
 &lt;script type="text/javascript"&gt; 
    document.write(unescape("%3Cscript src=\'" + document.location.protocol +
    "//zopim.com/?zopim\' type=\'text/javascript\'%3E%3C/script%3E"));
 &lt;/script&gt;  
&lt;!-- End of Zopim Live Chat Script --&gt; 
</code></pre>

<p>you just need to place it in the footer and ur done..</p>

<p>Can any body let me know how this works and from where i can learn this..</p>

<p>+</p>

<p>how can they even set the CSS with this and also the looks?</p>

<p>Awaiting for your replies...</p>

<p>Thanks </p>
