JS statement separator with commas
<p>I found the following js sample and am confused by the syntax.  Notice the statements are separated by commas instead of semicolons.  Are commas a valid statement separator in js?  I have not seen this before.</p>

<pre><code>    $('selector').each(function () {

            this.onclick = function () {
                this.select();
            },

            this.onblur = function () {
            },

            this.onfocus = function () {
            },

            this.onkeyup = function () {
            }
    });
</code></pre>
