validate combobox in javascript
<p>I have written the below code. But it does not show me the alert message when I don't select the other value and click onto the submit button.
I don't want to use <code>getElementbyId</code>. I am using the name attribute of the HTML.</p>

<pre><code>&lt;HTML&gt;
&lt;HEAD&gt;
&lt;TITLE&gt;ComboBox Validation&lt;/TITLE&gt;

   &lt;script Language="JavaScript"&gt;

   function validate()
   {

      if (document.comboForm.technology.value=="0") \
     {
         alert("Please Select Technology");
     }

   }
&lt;/script&gt;
&lt;/HEAD&gt;

&lt;BODY&gt;

&lt;form name="comboForm"&gt;
&lt;select name="technology"&gt;
    &lt;option value="0"&gt;Select&lt;/option&gt;
    &lt;option value="1"&gt;Java Server Pages&lt;/option&gt;
&lt;/select&gt;

  &lt;input type="submit" value="submit" onClick="validate();"&gt;
&lt;/form&gt;

&lt;/BODY&gt;
&lt;/HTML&gt;
</code></pre>
