onChange="this.form.submit()" for dropdowns
<p>Is there a reason why I shouldn't use:</p>

<pre><code>onChange="this.form.submit()"
</code></pre>

<p>instead of</p>

<pre><code>$(function () {
        $("#dropdown").live("change keyup", function () {
            $("#theform").submit();
        });
    });
</code></pre>

<p>Someone said it the onChange method shouldn't be used. I'm trying to find out the logic behind it.</p>

<p>The script basically submits the form on dropdown option change.</p>
