validatebox, adding a new rule

[chrwei]

I'm looking for a cleaner way to do this:

Code:

<script>
$.extend($.fn.validatebox.defaults.rules, {
	pickonemore: {
		validator: function(value,param){
			var hasone = false;
			$(param).each(function(k,p) {
				if ($(p).val() != "") hasone = true;
			});
			if(hasone) {
				$(param).each(function(k,p) {
					$(p).validatebox('disableValidation');
				});
			} else {
				$(param).each(function(k,p) {
					$(p).validatebox('enableValidation');
				});
			}
			return hasone;
		},
		message: 'Enter at least one value in this group.'
	}
});
</script>
<input id="box1" class="easyui-validatebox" type="text" name="box1" required="required" validType="pickonemore['#box1','#box2','#box3']"></input></td>
<input id="box2" class="easyui-validatebox" type="text" name="box2" required="required" validType="pickonemore['#box1','#box2','#box3']"></input></td>
<input id="box3" class="easyui-validatebox" type="text" name="box3" required="required" validType="pickonemore['#box1','#box2','#box3']"></input></td>

goal is to require one or more of the 3 values to be entered.  I'm using enableValidation/disableValidation calls because my new validator does not seemed to be called when a box is blank.  is there a better way?

After calling 'disableValidation' method, you need to call 'enableValidation' method again in some conditions. The simplest way to enable validation again is to recall 'enableValidation' method when value changed.

Code:

$('#box1,#box2,#box3').bind('keyup',function(){
	$('#box1,#box2,#box3').validatebox('enableValidation').validatebox('validate');
});

this is because if the value is selected and deleted, the validation won't fire since it doesn't run when the value is blank?  would it be a bad thing to run validation functions on blank values anyway?
