single checkbox enable/disable dropdown

11-08-2006

I've been looking all over and I can't seem to find what ought to be
simple.

I need to disable a drop down when a checkbox is checked, and enable it
when same checkbox is unchecked.

I've found any number of scripts to disable / enable a drop down but they
are all made to work with 2 different buttons, radio group selections, etc.
I can't seem to come up with one that can toggle off a single checkbox.

help please.

Thanks

i would make something more comprehensive to "normal" person

something like:

function foo(){
if (document.formname.checkboxname.checked) {
document.formname.dropdownlistname.disabled=true;
}else{
document.formname.dropdownlistname.disabled=false;
}

}

Here ur form tag
..
..
..
<input type="checkbox" name="checkboxname" value="something"
onclick="foo()">
..
..
..
Close form.
