Javascript to access control in MasterPage
<p>I have a textbox control Super1 in my MasterPage.</p>

<p>I am using javascript to access this control from my content page like this:</p>

<pre><code>&lt;asp:Content ID="ContentPage" ContentPlaceHolderID="ContentPlaceHolder1" Runat="Server"&gt;
&lt;script type="text/javascript"&gt;
    function Somethin() {
        {
            document.forms[0].elements['Super1'].value = "sdfsd";
            //document.getElementById('&lt;%=Super1.ClientID%&gt;').value = "sdfsdf";                
        }
    }
&lt;/script&gt;
&lt;/asp:Content&gt;
</code></pre>

<p>But while page load it says Super1 not found. How can I access Super1?</p>
