JavaScript Getting ID of A Div
<p>I have a <code>div</code> box with its <code>id</code> and an <code>textarea</code>.
When I click on my <code>div</code> box I should get <code>div</code> ID through Javascript and get it printed on the <code>textarea</code>. I have tried but its not working. when I click the text area it says "undefined". Kindly help me.</p>

<p>Here is the code:</p>

<pre><code>&lt;html&gt;
&lt;head&gt;

&lt;script type="text/javascript"&gt;
function get_id()
{
    var divEls = document.getElementsByTagName("div");
    var textEl = document.getElementById("mytextarea");
    textEl.value=divEls.id;
}
&lt;/script&gt;

&lt;/head&gt;
&lt;body&gt;
    &lt;div id="mydiv" onclick="get_id()" style='border-width:1px;border-color:#C0C0C0;border-style: solid;background-color:#C0C0C0;width:130px;height:10px;'&gt;
    &lt;/div&gt;

    &lt;textarea id="mytextarea"&gt; &lt;/textarea&gt;
&lt;/body&gt;
&lt;/html&gt;
</code></pre>
