Help me: Partial randomized answers in LimeSurvey 2.05+ - How can I do this?

:huh: Hi fellows.

Well, I`m here again. Hope someone can help me with this issue. And sorry my bad English. I am in Brazil.

I use LimeSurvey 2.05+ Build 140302.

I have a list radio question with 3 answers: 1 - aaaa, 2 - bbbb and 3 - NoAnswer. Just options 1 and 2 must be randomized. Option 3 should be fixed at the end. But I don't want NoAnswer in all my questions, so I set to "No" the specific option in General Settings.

Searching LimeSurvey Manual, I found two Workarounds with suggested scripts to do exactly what I need. I followed all the instructions, modifying the variables filterxsshtml to FALSE and shownoanswer to 0 in config.php, as stated, set the correct IDs in JavaScript, saved it in the source of the question, but nothing worked. All the answers were randomized.

What should I do? Can anyone help me? Keep in mind, fellows, that I'm not an IT professional. I'm a research specialist, very curious and darting in the mazes of coding.

Here are the Workarounds:

Partially Randomized Answers - Multiple Options & List (radio) questions - ENHANCED </br>
Partially Randomized Answers - Multiple Options & List (radio) questions

The scripts, with my sID, gID and qID. None worked, tested with Chrome, IE 9 and Firefox 20:

I think we can clean up that workaround a bit.

Assuming your answers codes are sequential numbers and you have set the answers to be randomized, adding this script to the question source will always place the last answer item at the end of the list. (you do not need to worry about the question ID - it will be automatically detected)

<script type="text/javascript" charset="utf-8">	
 
	$(document).ready(function() {
 
		// Identify this question
		var qID = {QID}; 
 
		// Find the number of answers
		var ansCount = $('#question'+qID+' li.answer-item').length;
 
		// Place the last answer created at the end of the list
		var answer = $( 'input[id$="X'+qID+ansCount+'"]');
		var answerItem = $(answer).closest('li');
		var answersList = $(answer).closest('ul');
		$(answersList).append(answerItem);
 
	});
</script>

Can I ask for more help?

If I want to set more than 1 answer to be fixed at the end of the list, what shoul I do?

e.g.:

1 - aaaa; 2 - bbbb; 3 - cccc; 4 - NoAnswer - 5 - OtherAnswer, randomizing itens 1, 2 and 3.

Thanks, again.

Use this script and, if necessary, modify the "fixedAnswers" variable.

<script type="text/javascript" charset="utf-8">	
 
	$(document).ready(function() {
 
		// The number of answers to be fixed at the end of the list
		var fixedAnswers = 2;
 
		// Identify this question
		var qID = {QID}; 
 
		// Find the number of answers
		var ansCount = $('#question'+qID+' li.answer-item').length;
 
		// Place the last n answers created at the end of the list
		var fixedIndex = fixedAnswers - 1;
		for (var i=0; i<fixedAnswers; i++) {
			var answer = $( 'input[id$="X'+qID+(ansCount-fixedIndex)+'"]');
			var answerItem = $(answer).closest('li');
			var answersList = $(answer).closest('ul');
			$(answersList).append(answerItem);
			fixedIndex--;
		}		
	});
</script>

Thanks tpartner for updating code. Many times we have to use the codes provided by client so we can not use sequential codes.I have one suggestion here. It will helpful if you can adapt your script so that it accepts an object specifying the response code and its position. I am thinking of using function like below :)
fixPostions({'respondseCode1':'position1','respondseCode2':'position2'})

It will helpful if you can adapt your script so that it accepts an object specifying the response code and its position...

That would require removing all of the specified answers from the list and then re-inserting them sequentially. Probably best done with a small jQuery pluging.

Add this plugin to the end of template.js:

	// A jQuery plugin to fix list-radio items in specific places
	// Requires a "positions" object with:
	// 		keys - numeric position, "first" or "last"
	//		values - answer codes
	(function( $ ){
 
		$.fn.lsRadioPositions = function(options) {  
 
			var opts = $.extend( {
				positions: {  }
			}, options);
 
			return this.each(function() { 
 
				var thisQuestion = $(this);
				var thisID = thisQuestion.attr('id').replace(/question/, '');
				var positionsArr = [];
 
				// Loop through the positions object
				$.each( opts.positions, function(position, code) {
					// Remove the option from the list
					$('li.answer-item[id$="X'+thisID+code+'"]').appendTo(thisQuestion);
 
					// Create an array of keys
					if (opts.positions.hasOwnProperty(position)) {
						if(position == 'first') {
							position = '1first';
						}
						positionsArr.push(position);
					}
				});
				positionsArr.sort();
 
				// Loop through the positions array
				$.each( positionsArr, function(i) {
 
					position = this;
					if(position == '1first') {
						position = 'first';
					}
					var thisCode = opts.positions[position]
 
					// Re-insert the option
					if(position == 'last') {
						$('ul.answers-list li.answer-item:last', thisQuestion).after($('li.answer-item[id$="X'+thisID+thisCode+'"]'));
					}
					else if(position == 1 || position == 'first') {
						$('ul.answers-list li.answer-item:first', thisQuestion).before($('li.answer-item[id$="X'+thisID+thisCode+'"]'));
					}
					else {
						$('ul.answers-list li.answer-item:eq('+(position-2)+')', thisQuestion).after($('li.answer-item[id$="X'+thisID+thisCode+'"]'));
					}
				});
			});
 
		};
	})( jQuery );


Then, call it something like this in the question source.
- Acceptable keys for the "positions" object are numeric position, "first" or "last".
- Values for the "positions" object are answer codes.
So, this example will always place answer codes A1 and A2 first and A6 last.

<script type="text/javascript" charset="utf-8">	
 
	$(document).ready(function() {		
 
		// Apply the radioPositions plugin to this question
		$('#question{QID}').lsRadioPositions( {
			positions: {
				2: 'A2', 
				last: 'A6', 
				first: 'A1'
			}
		} );  
    });
</script>
