What's the purpose (if any) of "javascript:" in event handler tags?
<p>I've been making a concerted effort to improve my javascript skills lately by reading as much javascript code as I can. In doing this I've sometimes seen the <code>javascript:</code> prefix appended to the front of event handler attributes in HTML element tags. What's the purpose of this prefix? Basically, is there any appreciable difference between:</p>

<pre><code>onchange="javascript: myFunction(this)"
</code></pre>

<p>and</p>

<pre><code>onchange="myFunction(this)"
</code></pre>

<p>?</p>
