body: <p>I have a problem that i want to access the normaltagCmt elements value:</p>
  
  <pre><code>&lt;div id="random no"&gt;
    &lt;div id="normaltagdialog"&gt;
    &lt;table style="width:100%; height:100%" border="2px"&gt;
      &lt;tr style="width:100%; height:13%" align="left"&gt;
        &lt;td&gt;
          &lt;label&gt; {$LANG.TEXT}&lt;/label&gt;
        &lt;/td&gt;
      &lt;/tr&gt;
      &lt;tr style="width:100%; height:59%; vertical-align:middle" align="center" &gt;
        &lt;td&gt;
          &lt;textarea id="normaltagCmt" style="width:90%; height:90%" &gt;&lt;/textarea&gt;
        &lt;/td&gt;
      &lt;/tr&gt;
      &lt;tr style="width:100%; height:13%"&gt;
        &lt;td&gt;
          &lt;label&gt; {$LANG.COLOR}&lt;/label&gt;
        &lt;/td&gt;
      &lt;/tr&gt;
      &lt;tr style="width:100%; height:15%; "&gt; 
        &lt;td&gt;
          &lt;table style="width:100%;height:100%"  cellpadding="2" cellspacing="2"&gt;
            &lt;tr id="colorPad" align="center"&gt;
            &lt;/tr&gt;
          &lt;/table&gt;
        &lt;/td&gt;
      &lt;/tr&gt;
    &lt;/table&gt;
  &lt;/div&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p>The script i have written above is a jquery dialog and this dialog opens many times.
  i want to get the value of normaltagCmt for a particular div with a specific random id.
  How can i get that in javascript?</p>
