Error when submitting a form

[meenu24]

The code is as given below. WHen I submit this form I get a error alert " 'document.form2' is null or not an object". I am confused of why this the error. Any suggestions welcome. Thanks for your time.
<script>
function sub2()
{
try
{
document.form2.submit();
}
catch(err)
{
al = err.description;
alert(al);
}
}
</script>
<form name="form2" action="browseservlet" >
<select name="category" onchange="sub2()">
<option value="">category</option>
<% for(int i = 0; i<category.length; i++)
{ %>
<option value="<%= urlct %>" ><%= category %>, <%= countct %> nos</option>
<% } %>
</select>
</form>

regards

Try renaming form2 to something like this_form.

The error means the javascript can't find the form.

This seems to work. It's likely something else is wrong within your script.

<script type="text/javascript">
<!--//
function submitForm() {
	document.this_form.submit();
}
//-->
</script>

<form name="this_form" action="[URL unfurl="true"]http://google.com">[/URL]
<select name="field" onChange="submitForm()">
<option value="">Select</option>
<option value="test">Test Me</option>
</select>
</form>

No the same piece of code is workign fine with other program. But the same is not working in this program. I am wondering why this erro comes.

is it possible that the code is being executed before the page is fully loaded? Trying throwing some alerts in there to see what's happening when.

Try viewing the page in Firefox. Then click on Tools, and Javascript Console. This most likely will give you the error and the line it's on.

Load the page then do a View/Source and copy that output to show here so we can see the whole code as it is rendered by the browser.

It is entirely possible that there is an error elsewhere on the page like an extra or missing bracket that screws up the javascript functions.

Also, you are mixing server-side and client-side script.
You should have a declaration on the page stating the script types rather than just a <script> tag.

You do not show it but I assume you have a complete HTML page with HTML, HEAD and BODY tags?. If you do not have these then a call to document.formname might fail since document would be refering to the HTML page object and I do not know how the script would operate if it HTML has not been properly declared.
