I've got a form with a texteditor (innova) in it. I'd like to validate using Javascript that some text has been entered. I get a run time error when I try
and read values from the form from within the JS validate routine.
The error is:
A Runtime Error has occurred.
Do you wish to Debug?
Line: 8
Error: 'TheContent.value' is null or not an object
The code is as follows, you need the innova text edit script source, to get the editor to work.

alert("Please enter text information");
return false;
} else {
return true;
}

What Tim wrote should work fine.
You got an error because you referenced an object called "myForm" that does not exists in your code. Your form has no id.
This could work too:
function ValidateForm(myForm) {
if (document.forms[0].element
alert("Please enter text information");
return false;
} else {
return true;
}
}
I do not see any problem with your Javascript code, look like a issue with InnovaEditor(),
I just commented the script line to verify that..
just try following script..
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<title>Test</title>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
<script SRC='/Editor/scripts/innov
<script TYPE="text/javascript">
function ValidateForm(myForm) {
if (myForm.TheContent.value==
alert("Please enter text information");
return false;
} else {
return true;
}
}
</SCRIPT>
<head>
</head>
<body>
<form action="" method="get" onsubmit="return ValidateForm(this)">
<table width="75%" border="1">
<tr>
<td>Text Info</td>
<td><textarea id="TheContent" name="TheContent" rows=10 cols=48></textarea>
<script>
var oEdit1 = new InnovaEditor("oEdit1");
oEdit1.REPLACE("TheContent
</script></td>
</tr>
<tr>
<td> </td>
<td><input type="submit" name="Submit" value="Submit"></td>
</tr>
</table>
</form>

if( document.getElementById( 'TheContent' ).value == '' ) {
alert( 'Please enter text information' ) ;
return false ;
} else {

work?
