disabling dropdowns and radiobuttons 2

[JavaRavyn]

Hey ya'll,

I am trying to disable some dropdown lists and radio buttons if certain values are retrieved from a table in the db. If A came back, i'd like to disable a set of radio buttons and two select boxes.

Any ideas?

thx,

use the disable property:

document.formName.elementName.disabled = true;

or to enable:

document.formName.elementName.disabled = false;

Does disabling equate to greying out the box?

I am painting a form on a jsp, and I would like to disable radiobuttons and dropdown menus based on what the user picks earlier in the form. disabled = true doesn't seem to be working.

If you can suggest anything else, I would appreciate it.
thx,

I'm assuming that you are using javascript to validate your form?..If your form name is myForm and the thing you want to grey out is myElement it would be

if (whatever == "a") {
document.myForm.myElement.disabled = true;
}

it might not work on dropdowns..I'm not sure but I know it will work on radio buttons

Hey ya'll,

Thanks for all of the help. When I want to disable, I have to actually name which radiobutton I want disabled since there is more than one in the group (ie small medium or large and I want to disable small if childFlag = 'Y').

ie - document.forms[0].rbSeating[2].disabled = true ;
this disables the 3rd button in the list.
