Create unique options in array question 2 years 3 months ago #57449

paulfiner OFFLINE Expert Lime Posts: 81 Thank you received: 1 Karma: 1	I have an array type question with some attributes down the side and three columns labelled Most important, 2nd most important and 3rd most important. Is there a way to stop more than one attribute being selected as, say, Most important? Cheers Paul

paulfiner OFFLINE Expert Lime Posts: 81 Thank you received: 1 Karma: 1	I've tried the Array Column question and the problem is the other way around i.e. an attribute can be selected as Most Important and 2nd Most important. I'm happy to do it with some Javascript if someone can show me how. I don't want to use the built in ranking question. Cheers Paul

tpartner OFFLINE LimeSurvey Team Posts: 2870 Thank you received: 428 Karma: 246	Paul, are these radios or checkboxes? Do you want all columns to only allow one checked item or only one column? Can you attach a sample question (preferably in English)?

paulfiner OFFLINE Expert Lime Posts: 81 Thank you received: 1 Karma: 1	Hi Tony, These are radiobuttons and should only allow 1 answer per column and not the same answer across columns. Rows: Price Speed Reliability Extras Columns: Most Important, 2nd Most Important, 3rd Most Important If Speed is picked in column 1 then it can't be picked in columns 2 or 3

paulfiner OFFLINE Expert Lime Posts: 81 Thank you received: 1 Karma: 1	Here's what I have at the moment So each column must only have one answer and each row should have only one answer too.

Add this script to the source of the question text or help. Replace "QQ" with your question ID.

The script puts a listener on the answer cells. When one is clicked, if there are any others with the same class (same column) that have a checked radio, an alert is popped up and the radio is unchecked.

<script type="text/javascript" charset="utf-8">
 
	$(document).ready(function() {
 
		var qID = QQ;
 
		$('#question'+qID+' table.question tbody td').click(function () { 
			var cellClass = $(this).attr('class');
			var parent = $(this).parent();
			setTimeout(function() { 
				if($('.'+cellClass+' input[type=radio]:checked').length > 1) {
					alert ("Can't do that!");
					$('.'+cellClass+' input[type=radio]', parent).attr('checked', false); 
				}
			}, 100);
		});
 
	});
 
</script>

Cheers,
Tony

paulfiner OFFLINE Expert Lime Posts: 81 Thank you received: 1 Karma: 1	Hi Tony Is there anyway to make the clicked radiobutton that causes the error message to show to be the one that stays clicked and the original radio button to become unchecked? If this could be done without showing the error message that would be even better! Cheers Paul

I haven't had time to test in all browsers (I'm working on your drag-n-drop images)

Cheers,
