JS help - checkboxes
I have a little script that throws up an alert when more than 1 checkbox
is selected.However, is there some code I can put in this script that
will also prevent anything else in the cold fusion page from processing
until the more than one checkbox problem is corrected?Here's the
script:
SCRIPT LANGUAGE=_javascript_
!-- Begin
function anyCheck(form) {
var total = 0;
var max = form.type_no.length;
for (var idx = 0; idx max; idx++) {
if (eval(document.registration.type_no[ + idx + ].checked) == true)
{
total += 1;
if (total 1) alert(You cannot select more than 1 registration type);
}
}
}
//End --
/script
TIA

RE: JS help - checkboxes
If your calling that script from the OnSubmit function of your form tag,
simply return FALSE to the call:
FORM ACTION="" ACTION PAGE NAME=myFORM >
anyCheck('myForm')
Then in the script:
if (eval(document.registration.type_no[ + idx + ].checked) == true)
{
total += 1;
if (total 1) alert(You cannot select more than 1 registration type);
return false
}
}
return true
This is of course you need no other validation

RE: JS help - checkboxes
Would it make more sense to use radio buttons, which only allow one selection?

RE: JS help - checkboxes
Glad to help.Here's one more tip.If you want HTML checkboxes and radio buttons to activate by clicking on the label (like other form-based apps), try this snippet of code:
LABEL FOR="" TYPE=radio ID=RB1 NAME=Foo VALUE=1Option 1/LABEL
I don't think it works on every browser, but it works on most modern ones and the others just ignore the LABEL tags.Note that the FOR parameter of the LABEL tag must match the ID parameter of the radio button or checkbox.
