title: Get unanswered questions (Radio buttons) JQuery
body: <p>I want to validate whether all the questions are answered or not and display a message <strong>"Answer is Required</strong>". 
  Each of the question has YES and NO  Radio buttons.</p>
  
  <p>The following piece of code places "Answer is required" for every question even though one of the Radio button is checked. But I want the message to be shown when none of the Radio button or selected for that question.</p>
  
  <pre><code>  $('input:radio').not(':checked').closest('td').next().html("Answer is Required");
  </code></pre>
  
  <p>HTML :</p>
  
  <pre><code>&lt;table border="0"&gt;
      &lt;tr&gt;
          &lt;td class="TextBold"&gt;1.&lt;/td&gt;
          &lt;td class="TextBold" align="left" valign="middle"&gt;Content of Question 1 :&lt;/td&gt;
          &lt;td class="TextBold" align="left" valign="middle"&gt;
              &lt;table id="ctl00_DefaultContent_ctl01" border="0"&gt;
                  &lt;tr&gt;
                      &lt;td&gt;
                          &lt;input id="ctl00_DefaultContent_ctl01_0" type="radio" name="ctl00$DefaultContent$ctl01" value="Yes" /&gt;
                          &lt;label for="ctl00_DefaultContent_ctl01_0"&gt;Yes&lt;/label&gt;
                      &lt;/td&gt;
                      &lt;td&gt;
                          &lt;input id="ctl00_DefaultContent_ctl01_1" type="radio" name="ctl00$DefaultContent$ctl01" value="No" /&gt;
                          &lt;label for="ctl00_DefaultContent_ctl01_1"&gt;No&lt;/label&gt;
                      &lt;/td&gt;
                  &lt;/tr&gt;
              &lt;/table&gt;
          &lt;/td&gt;
          &lt;td class="TextBold" align="left" valign="middle"&gt;&lt;/td&gt;
      &lt;/tr&gt;
  &lt;/table&gt;
