Changing a hidden form element value

aztarac · Jan 31, 2007

Hi y'all !

I'm an absolute ASP newbie and need some help.
I want to be able to change a hidden form element value on an ASP page.
The following generates this error:

Microsoft VBScript runtime error '800a01a8'
Object required: ''
/test.asp, line 13

Maybe 'document' is wrong but it would work in VBScript on client side.

Thanks in advance for any help.

<html>
<head>
<title>Test Page 1</title>
</head>
<body>

<form method="POST" action="--WEBBOT-SELF--">
<input type="hidden" name="test" value="xxx">
</form>
</body>

<%
document.GetElementById( "test" ).value = "hello"
%>

</html>

Neither the form element nor the document object exists on the server, which is where you are trying to change them with your script. Once the web page has been served to the client, the Active Server Pages script does not exist and cannot affect anything.

Code:

<%
document.GetElementById( "test" ).value = "hello"
%>

You have to put that in <script> tags and NOT escape into server side (eliminate <% and %>)
