I don't know the exact code (I always forget JS details) but the basic idea would be to give your checkboxes IDs in the JSP, then use getElementById() to grab the DOM nodes for them and just do (node.checked == true), then && the results. And your submit would have call the method that validates as its onClick event and only submits the form if the validation passes.
JavaScript is ubiquitous enough that Google has plenty of results for it, so have a look: http://www.google.com/search?q=javascript+checkbox+group&btnG=z34r%3C%7C -%7C Hopefully that ought to point you in the right direction. ~DVA -----Original Message----- From: mojoRising [mailto:[EMAIL PROTECTED] Sent: Friday, May 09, 2008 2:34 PM To: user@struts.apache.org Subject: RE: How to validate a checkboxlist? I am using struts 2.0.11, and with the validation framework, client-side validation is of course done using javascript: http://struts.apache.org/2.x/docs/client-validation.html Javascript must be used for my project so I have no problem requiring it. The client side (javascript)validation works perfectly for text boxes...but I don't see how to make it check that a checkboxlist has at least one box checked? Has anyone ever done this?
