forms[0] error 1

ksoong · Apr 14, 2001

Hi all,

I am working on a server that has a predefined form page.
The form page follows like:

<form action=blah.cgi method=post>
<input type=hidden name=name value="Mr. Jones">
</form>

There is no name in the form and I can't change that predefined form to have a name. I want to do this.

<script>
alert("Hi there "+document.forms[0].name.value);
</script>

But it's giving me an error that says:

document.forms.0.name is null or not an object

why is this not working? according to javascript specs this should work shouldn't it?

Hi Kenneth,

What you need to do is to load the form first or put the <script> after the form

Try the following..

solution 1
------------
<html>
<head>
<script>
function setDefault() {
alert("Hi there "+document.forms[0].name.value);
}
</script>
</head>
<body onload="setDefault()">
<form action=blah.cgi method=post>
<input type=hidden name=name value="Mr. Jones">
</form>
</body>
</html>

or

solution #2
------------
<html>
<body>
<form action=blah.cgi method=post>
<input type=hidden name=name value="Mr. Jones">
</form>
<script>
alert("Hi there "+document.forms[0].name.value);
</script>
</body>
</html>

hope this helps.. =)
