Hi,

can anybody help (or point to an example) of how to validate a mandatory multiple-choice-with-comment type of question. Expression should validate that all checked options must have something (at least 5 characters) typed in the comment field.

thanks!

I'm not sure you can do that with Expression Manager but you can with JavaScript.

Set up your survey to use JavaScript and add something like this to the source of the question:

<script type="text/javascript" charset="utf-8">	
	$(document).ready(function() {
 
		// Identify this question
		var thisQuestion = $('#question'+{QID}+'');
 
		// Interrupt the submit process
		$('#movenextbtn, #movesubmitbtn').bind('click', function () {
 
			// Reset the errors
			var commentError = 0;
			$('li.answer-item', thisQuestion).css('background-color', 'transparent');
 
			// Check for invalid comments
			$('input.checkbox:checked', thisQuestion).each(function(i) {
				var thisItem = $(this).closest('li.answer-item');
				var thisComment = $('input[type="text"]', thisItem);
				if($(thisComment).val().length < 6) {
					$(thisItem).css('background-color', 'pink');
					commentError = 1;
				}
			});
 
			// Comment failed so abort submit
			if(commentError == 1) {
				alert("Comments must be at least 5 characters.");
				return false;
			}
		});
 
	});
</script>
