title: How to disable a certain radio button in a RadioButtonList in Javascript
body: <p>I'm at my wit's end when it comes to this. JavaScript definitely isn't my strong suit and I've been trying to google for a solution. Here's the code I have:</p>
  
  <pre><code>&lt;asp:RadioButtonList ID="Group1Most" onClick="disable('Group1Most', 'Group1Least')" runat="server" &gt;
                              &lt;asp:ListItem Value="1"&gt; |&lt;/asp:ListItem&gt;
                              &lt;asp:ListItem Value="2"&gt; |&lt;/asp:ListItem&gt;
                              &lt;asp:ListItem Value="3"&gt; |&lt;/asp:ListItem&gt;
                              &lt;asp:ListItem Value="4"&gt; |&lt;/asp:ListItem&gt;
                          &lt;/asp:RadioButtonList&gt;
  
  &lt;asp:RadioButtonList ID="Group1Least" runat="server" &gt;
                              &lt;asp:ListItem Value="1"&gt; This and That&lt;/asp:ListItem&gt;
                              &lt;asp:ListItem Value="2"&gt; Fire and Ice&lt;/asp:ListItem&gt;
                              &lt;asp:ListItem Value="3"&gt; Black and Tan&lt;/asp:ListItem&gt;
                              &lt;asp:ListItem Value="4"&gt; Smith and Wesson&lt;/asp:ListItem&gt;
                          &lt;/asp:RadioButtonList&gt;
  </code></pre>
  
  <p>And here's the JavaScript:</p>
  
  <pre><code>function disable(index, control)
      {  
          var selected=($("[ID$=_"+index+"] input[type=radio]:checked").val());
  
          //The rest of the stuff that I can't figure out
      }
  </code></pre>
  
  <p>What I want to do is whenever you click a radio button on the <code>Group1Most</code> RadionButtonList, it will disable the corresponding radio button on the <code>Group1Least</code> RadioButtonList. The problem is I can't figure out how to select an individual radio button within the RadioButtonList. Can anybody help me?</p>
