Validating a checkbox in javascript Flir hookup cam

It is checking that at least one checkbox is checked.I only don't like that I have to manually call validate for one Checked-Validator on form submission. Of course, if you want better support than that, you could get all checkboxes, loop through them and check if they have the class, then see if there's more than one checked. When I copied and pasted your code into a html file and ran it, my FF and IE spat out an error.I have some checkboxes in a form that I'd like to validate (check to ensure that at least one has been ticked): I need to pass along multiple checkbox responses to my PHP script and therefore need to keep checkboxes named name="response[]".When I do this, I get the error "document.surveyform.response has no properties" Any idea what change I can make to the javascript so that I can name my checkboxes name="responses[]" ?

I'm trying to use this link as my resource: understand how it works for textboxes, but how do you make it detect form validation for checkboxes?It makes your page much more user-friendly, and takes out the frustration of having to fill out the same form repeatedly.It's also very precise, as you can point out the exact field where there's a problem.A Java Script check is useful because it stops the form from being submitted if there is a problem, saving lots of time for your readers.The CGI script is still more reliable, as it always works regardless of whether Java Script is enabled on the client-side or not; but having this extra safety barrier is a nice thing to have in place.
