Checkbox validation dependant on radio

Copy linkTweet thisAlerts:

How do I make a checkbox validation dependant on radio button?

so:

if [radio1] is clicked;
then [checkbox] must be clicked

else if [radio2] is clicked;
then [checkbox] does not have to be clicked

I tried disabling it but it still gave me the alert

[CODE]
function disable_validation()
{
if(GetElementById(“radio2”).checked)

{
GetElementById(“checkbox”).disabled=true;
}
}[/CODE]

is there another way of saying it so it turns it off?

thanks for helping this noob

@2AMauthorSep 03.2009 — nevermind.. i figured out a trick

[CODE]
function disable_validation()
{

if(GetElementById("radio2").checked)

//autocheck to suppress alert
GetElementById("checkbox").checked=true;
}[/CODE]

I am anyway hiding it if radio2 is checked:

[CODE]function R2_onclick()
{
disable_validation()
document.getElementById('entire_tr_with_checkbox').style.display = 'none';
}[/CODE]

It works, but is this a decent way of doing it?
