Check which html element triggers onclick
<p>I have html like below:</p>

<pre><code>&lt;div onclick=" callJavascript()"&gt;

&lt;span id="abc"&gt; abc &lt;/span&gt;
&lt;span id="def"&gt; def &lt;/span&gt;
&lt;span id="ghi"&gt; ghi &lt;/span&gt;

&lt;/div&gt;
</code></pre>

<p>When I click 'abc'  or 'ghi', is there anywhere inside <code>function callJavascript()</code>, to find out which span id I clicked on ?</p>
