Check box trick?

[knickerlas]

Hi guys
Can some one tell me how to do this:

If you have threee checkboxes and a user ticks one: The other two automatically tick on the screen aswell.

Like:
[] chk1
[] chk2
[] chk3

If I tick 'chk1', the other two get checked onscreen also.

Many thanks

Nick

Nick,

Try doing something like:

function check_all() {
for (i=0;i<document.forms[0].length;i++) {
if (document.forms[0].elements.type == 'checkbox') document.forms[0].elements.checked = true;
}
}

And use an appropriate event handler (onclick) on each of the checkboxes.

Cheers,

David

Thanks David.
My Javascript skills are non-existent, it's my next project.
I just wish there were more hours in the day, there's always more to learn!

Thanks again

You'll get them automatically now your in the 'chain'.
There should be a way to get email updates without having to 'answer' but sadly not.
