Set form value with JavaScript
<p>How can I set a value here</p>

<pre><code>&lt;input type="text" name="3b9bcc77d6b729eaa82d68a5768edfca" value="" class="textCtrl" id="ctrl_3b9bcc77d6b729eaa82d68a5768edfca" autofocus="true" autocomplete="off"&gt;
</code></pre>

<p>I tried with this code </p>

<pre><code>document.getElementById('ctrl_2bf2afd36152a19957d999bc7a32064e').value = 'cccc'; 
</code></pre>

<p>but anything appends.
ps. I used this extension for Chrome for injecting JavaScript code
