Recieving Error: 'theForm' is undefined

[Nathan Sokalski]

I have an ASP.NET application which is giving the following JavaScript
error:

'theForm' is undefined

However, when I did a View Source I noticed that ASP.NET added the following
code:

<script type="text/javascript">
<!--
var theForm = document.forms['form1'];
if (!theForm) {
theForm = document.form1;
}
function __doPostBack(ev entTarget, eventArgument) {
if (!theForm.onsub mit || (theForm.onsubm it() != false)) {
theForm.__EVENT TARGET.value = eventTarget;
theForm.__EVENT ARGUMENT.value = eventArgument;
theForm.submit( );
}
}
// -->
</script>

I was told in a previous posting that the reason for the error is that the
script containing the declaration and assigning of a value to it occur
before the

Re: Recieving Error: 'theForm' is undefined

If the page does not have a form named "form1", then the variable
declaration will fail and the variable "theForm" won't be able to be
created.


var theForm = document.forms['form1'];

Re: Recieving Error: 'theForm' is undefined

either the script referencing theForm occurs before the declaration or
form1 is not defined (a form tag with name form1).

And, remember "Form1" != "form1".

var theForm = document.getEle mentById("form1 ");

Re: Recieving Error: 'theForm' is undefined

He can't try that, Alexei, because the code is being injected by ASP.NET.

He can't change the embedded javascript funtions, if he's using ASP.NET 2.0.
There's a chance he mioght be able to do that, if he's using ASP.NET 1.1.

All he'd have to do is edit the scripts located in
\wwwroot\aspnet _client\system_ web\1_1_4322.

The problem doesn't seem to be that the function is buggy, though.

If Nathan were to rename the page's form to "form2",
instead of naming it "form1", he should see this :

<script type="text/javascript">
<!--
var theForm = document.forms['form2'];
if (!theForm) {
theForm = document.form2;
}
function __doPostBack(ev entTarget, eventArgument) {
if (!theForm.onsub mit || (theForm.onsubm it() != false)) {
theForm.__EVENT TARGET.value = eventTarget;
theForm.__EVENT ARGUMENT.value = eventArgument;
theForm.submit( );
}
}
// -->
</script>

Notice that the source reveals that the script has picked up the form's new name.

If that doesn't show up, and the error persists, it's a timing problem.
The javascript is running before the form has been rendered.
