First I'd use radio buttons if they have to answer one answer for each
question. That being said, here's my code to do that, fair warning
though, JS is not my specialty so probably this isn't the most elegant
solution!
My form just had a series of questions with radio buttons, no other
elements. If you have other elements, you'll need to modify this
javascript accordingly.
<!--start javascript include for head -->
// validate radio buttons
function validateForm() {
// build array
var h = "";
var n = "";
var c = 0;
var a = new Array();
for (i=0; i < document.myForm.elements.length; i++) {
if (document.myForm.elements[i].type == "radio") {
n = document.myForm.elements[i].name + "z"; // add letter to
avoid
search conflicts
if (h.indexOf(n) == -1) {
a[c] = n;
h = h + n;
c++;
}
}
}
// compile number of checked radios
var d = 0;
for (i=0; i < document.myForm.elements.length; i++) {
if ( (document.myForm.elements[i].type == "radio") &&
(document.myForm.elements[i].checked) ) {
d++;
}
}
// compare number of checked radios to length of array
if (d != a.length) {
alert ("Please attempt to answer all questions.");
return false;
}
return true;
}
<-- end js include>
<form method="post" action="yourAction.cfm" name="myForm" onsubmit="return
validateForm(this);">
</form>
