RE: How to validate a checkboxlist?

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:

-%7C Hopefully that ought to point you in the right direction.

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?
