Hi .
Am very sorry for late reply.

Thank you all. .
I have a dynamic page
I just want to disable a field based on a selection of combo box..

Here is my code

On the view source-->

But it is not working. 1st alert gives me false and second alert gives me true. But on the page it is not disabled.

Can any one guide me
It is defined on the page

String operation = session.getAttribute("Operation").toString();
Where this operation has a value as "add"

Iam missing single quotes. So i tried to give directly as
If i give like that am getting an error as Attribute add has no value in the console. I dono how should i pass the string into the function.
Kindly help me
In the browser it is like

Where add is the value of operation.. Am getting an error like add is undefined.. Am not sure why am getting this error..
This is the actual code

In which metaInfo.getColumnValidator() refers to check function in java script.

Opertaion and rowCnt are a java variables....

Please be sure to use code tags when posting code to the forums

Thank you.

What is check in the function onChangeWrapper?

Check is another javascript function that is used to validation

In my last post i have given a wrong function arguments. Please consider this
onchange="onChangeWrapper(check(this,"+operation+", "+rowcnt+"));
I am just calling a java script function on change of value in drop down box.

<% String operation=request.getAttribute("operation");
int rowcnt=((Integer)idx).intValue;

onchange="onChangeWrapper(check(this,"+add+", "+rowcnt+"));

Have written functions in seperate js file. While loading am getting javascript undefined error in


Could any one guide me
