html question (check box)

[lrbtav]

Hi, I have a site with a built in 'contact us' form; how can I force
the user to check a certain check box before allowing them to submit
the form? This site is hosted on an ASP enabled godaddy server, but I
figured there was some html or js function that would accomplish this.
Thanks

HTML: impossible
JS: unreliable
Handle it in ASP after the form is submitted

Well, TRY to handle it with JS, but make sure of it on the server. It saves
a lot users an unneccessary trip to the server, get the contents, load the
page, just to get the error that he forgot to check a box after.

In the form tag add an onsubmit which calls a JavaScript function to
check whether your checkbox is actually checked. If it isn't return
false with a message of some kind. If it is checked, return true and
then (as others have said) check via ASP to ensure the box was checked.

Easy enough..

But makes things unneccessary complex due to the double validation

To use a JS function, would something like this work:

function checkscript() {
if (window.document.form.BoxChecked.checked=false) {
alert('Warning: Please agree to our terms of service.');
return false;
}
else if (window.document.form.BoxChecked.checked=true) {
alert('Thank you for your business!');
return true;
}

? thanks
