Question

this is my first post here on stackoverflow and am very impressed by the site!

My question is about the jQuery Validation plugin…specifically about the minlength method.
I have a group of checkboxes and I want to know if at least 2 boxes were checked.

http://docs.jquery.com/Plugins/Validation/Methods/minlength#length

at this link there is documentation about the minlength method being used with a regular input box, but not a checkbox. Can anyone help me on how to use if for checkboxes?

There isn’t a default method. Fortunately you can add it.

jQuery.validator.addMethod('has2selected',function(value, element) {
return $(element).filter(':checked').length >= 2;
}, 'the error message');

EDIT: I read again the documentation and the minlength should work (if wasn’t the case the above code can make the job). You didn’t post the code so I’m not sure if this is causing the error, but in your post is minLength it has to be minlength.
