Hi friends

I want to disable my text box using java script.

Here "a" is the line number where change dynamically

var remarks="remarks"+a
var remarks_1=document.getElementById(remarks)

document.f_update.remarks_1.disabled== "true";

f_update is the form name.

It is not working..
thanks in advance

Perhaps if you change "f.remarks_1" back to "f_update.remarks_1"...

Why would you find it by id than try to look it up via the form?

All you would need to do is

remarks_1.disabled=true;
