Jan, we can meet your requirements by using the workaround mentioned above with a little extra JS to automatically trigger the checking of a multiple options question if a radio in column 1 or 3 of an array is checked.

1) Add the rankFilter function from the workaround to your template.js file.

2) On page 1, create your array question and a multiple options question (we'll hide the multiple options with JavaScript). Both questions must have identical sub-questions and sub-question codes.

3) Place the following script in the source of one of the questions on page 1. Replace "AA" (line 7) with the question ID of the array question and "MM" (line 7) with the question ID of the multiple options question. The "[1,3]" param dictates which columns of the array will trigger checking the multi-options. This script hides the multi-options question and interrupts the next/submit function to automatically check the appropriate box in the multi-options for all radios checked in columns 1 and 3 of the array.
<script type="text/javascript" charset="utf-8">
 
	$(document).ready(function() {
 
		// Call the function
		// Params = Array ID, Hidden Multi-opt ID, "Trigger" columns (in square brackets, separated by comma)
		triggerCells(AA, MM, [1,3]);
 
		function triggerCells(q1ID, qHiddenID, columns) {
 
			// Add a class to all array cells in "trigger" columns
			$(columns).each(function(i) {
				var colIndex = (this-1);
				$('#question'+q1ID+' table.question tbody').each(function() {
					$('td:eq('+colIndex+')', this).addClass('trigger');
				});
			});
 
			// Hide the hidden question
			$('#question'+qHiddenID+'').hide();
 
			// Find the survey and group IDs
			if($('input#fieldnames').length != 0) {
				var fieldNames = $('input#fieldnames').attr('value');
				var tmp = fieldNames.split('X');
				var sID = tmp[0];
				var gID = tmp[1];
			}
 
			// Interrupt next/submit function 
			$('form#limesurvey').submit(function(){
				// Clear the hidden question
				$('#question'+qHiddenID+' li .checkbox').attr('checked', false);
 
				// Loop through all rows of the array and if a "trigger" cell is checked, check the corresponding box in the hidden question
				$('#question'+q1ID+' table.question tbody').each(function(i) {
					if($('.trigger .radio:checked', this).length > 0) {
						$('#question'+qHiddenID+' li:eq('+i+') .checkbox').attr('checked', true);
					}
				});
 
				return true;
			});
		}
 
	});
 
</script>

4) On page 2, Create a multiple options question and the ranking question (we'll hide the multiple options with JavaScript). These questions also need to have identical sub-questions and sub-question codes as those on page 1.

5) Set the multiple options on page 2 to be filtered by the multiple options on page 1.

6) Place the following script in the source of one of the questions on page 2. Replace "MM" with the ID of the multiple options question and "RR" with the ID of the ranking question. Do not modify the "1". This calls the rankFilter function which hides all choices in the ranking question except those checked in the page 1 multi-options.
<script type="text/javascript" charset="utf-8">
 
	$(document).ready(function() {
 
		rankFilter(MM, RR, 1);
	});
 
</script>
Cheers,
Tony Partner

Luke, due to your somewhat aged LS version, we can do something similar to Jan's solution but will need to pass the sub-question codes and values to page 2 via a couple of hidden short-texts and a hidden boilerplate question. We'll also need to modify the functions slightly to handle the different method of passing data.

1) Add the following variation of the workaround function to your template.js file:
// A function to filter choices in a ranking question
function rankFilter2(q1ID, q2ID) {	
 
	// Hide the boilerplate
	$('#question'+q1ID+'').hide();
 
	// Find the survey and group IDs
	if($( 'input#fieldnames' ).length != 0) {
		var fieldNames = $( 'input#fieldnames' ).attr('value');
		var tmp = fieldNames.split('X');
		var sID = tmp[0];
		var gID = tmp[1];
	}
 
	// Handle the option codes and text passed from page 1
	var triggers = $('#question'+q1ID+' .triggers').text().split(',');
	var nonTriggers = $('#question'+q1ID+' .nonTriggers').text().split(',');
 
	$(triggers).each(function(i) {			
		// Split out the answer code and value
		var tmp2 = this.split('|*|');
		var ansCode = tmp2[0];
		var ansTxt =  tmp2[1];
 
		// If option is checked and not in rank choices or output, add it to the rank choices
		if($('#question'+q2ID+' select.select option[value="'+ansCode+'"]').length == 0 && $('#question'+q2ID+' .output input[id^="fvalue_"][value="'+ansCode+'"]').length == 0) {
			$('<option value="'+ansCode+'">'+ansTxt+'</option>').appendTo('#question'+q2ID+' select.select');
		}
	});
 
	$(nonTriggers).each(function(i) {			
		// Split out the answer code and value
		var tmp2 = this.split('|*|');
		var ansCode = tmp2[0];
		var ansTxt =  tmp2[1];
 
		// Remove it from the rank choices
		$('#question'+q2ID+' select.select option[value="'+ansCode+'"]').remove();
		// Remove it from the rank output and reset hidden values
		$('#question'+q2ID+' .output input[id^="fvalue_"][value="'+ansCode+'"]').attr('value', '').siblings('input.text').val('').siblings('img').hide();
	});
 
	// Clean up empty inputs in the rank output table
	$('#question'+q2ID+' .output table tr').each(function(i) {
		var nextRow = $(this).next('tr');
		if($('input.text', this).val() == '' && $('input.text', nextRow).val() != '') {
			$('input.text', this).val($('input.text', nextRow).val());
			$('input.text', nextRow).val('');
			$('input[id^="fvalue_"]', this).attr('value', $('input[id^="fvalue_"]', nextRow).attr('value'));
			$('input[id^="fvalue_"]', nextRow).attr('value', '');
		}
	});
 
	// Show the scissors for the last populated rank output row
	$('#question'+q2ID+' .output table img[id^="cut_"]').hide();
	$('#question'+q2ID+' .output table input.text[value!=""]:last').siblings('img[id^="cut_"]').show();
 
	// Hide extra rank output rows
	var optNum = $(triggers).length;
	$('#question'+q2ID+' .output table tr').hide();
	$('#question'+q2ID+' .output table tr:lt('+(optNum+1)+')').show();
 
	maxAnswersFix();
 
	// A listener to work around the built in max-answers function
	$('#question'+q2ID+' td.rank').click(function (event) {
		maxAnswersFix();
	});
 
	// A work around for the built in max-answers function
	function maxAnswersFix() { 
		$('#question'+q2ID+' select.select').attr('disabled', true);
		$('#question'+q2ID+' td.output tr:visible').each(function(i) {
			if($('input.text', this).val() == '') {
				$('#question'+q2ID+' select.select').attr('disabled', false);
			}
		});
	}
}

2) On page 1, create your array question and two short text questions (we'll hide the short texts with JavaScript).

3) Place the following script in the source of one of the questions on page 1. Replace "AA" (line 7) with the question ID of the array question, "HH1" and "HH2" (line 7) with the question IDs of the short-text questions. The "[1,2,3,4]" param dictates which columns of the array will load "triggers". This script hides the short-text questions and interrupts the next/submit function to load the first short-text with codes and values of subquestions to show in the ranking (triggers) and loads the second short-text with the ones to remove/hide (non-triggers).
<script type="text/javascript" charset="utf-8">
 
	$(document).ready(function() {
 
		// Call the function
		// Params = Array ID, Hidden Multi-opt ID, "Trigger" columns (in square brackets, separated by comma)
		storeTriggers(AA, HH1, HH2, [1,2,3,4]);
 
		function storeTriggers(q1ID, qHidden1ID, qHidden2ID, columns) {
 
			// Add a class to all array cells in "trigger" columns
			$(columns).each(function(i) {
				var colIndex = (this-1);
				$('#question'+q1ID+' table.question tbody').each(function() {
					$('td:eq('+colIndex+')', this).addClass('trigger');
				});
			});
 
			// Hide the hidden questions
			$('#question'+qHidden1ID+'').hide();
			$('#question'+qHidden2ID+'').hide();
 
			// Find the survey and group IDs
			if($('input#fieldnames').length != 0) {
				var fieldNames = $('input#fieldnames').attr('value');
				var tmp = fieldNames.split('X');
				var sID = tmp[0];
				var gID = tmp[1];
			}
 
			// Interrupt next/submit function 
			$('form#limesurvey').submit(function(){
 
				var triggers = new Array();
				var nonTriggers = new Array();
 
				// Loop through all rows of the array build an array of the "trigger" codes and text
				$('#question'+q1ID+' table.question tbody').each(function(i) {
					var optTxt = $('th', this).text();
					var optTmp = $(this).attr('id').split('X'+gID+'X'+q1ID+'');
					var optCode = optTmp[1];
					var optString = optCode+'|*|'+optTxt;
					if($('.trigger .radio:checked', this).length > 0) {
						triggers.push(optString);
					}
					else {
						nonTriggers.push(optString);
					}
				});
 
				// Populate the hidden questions
				$('#question'+qHidden1ID+' input.text').val(triggers);
				$('#question'+qHidden2ID+' input.text').val(nonTriggers);
 
				return true;
			});
		}
 
	});
 
</script>

4) On page 2, Create a boilerplate question and the ranking question (we'll hide the boilerplate with JavaScript). The ranking question must have identical sub-questions and sub-question codes as the array on page 1.

5) For the boilerplate text, use two {INSERTANS} tags to pipe in the answer from the page 1 short-text questions and wrap them in <span> elements with classes "trigger" and "nonTriggers". So the source of the boilerplate should look something like (with correct IDs, of course):
<span class="triggers">{INSERTANS:11111X22X3}</span><span class="nonTriggers">{INSERTANS:11111X22X4}</span>

6) Place the following script in the source of one of the questions on page 2. Replace "BB" with the ID of the boilerplate question and "RR" with the ID of the ranking question. This calls the rankFilter2 function which hides all choices in the ranking question except those passed from page 1 as "triggers".
<script type="text/javascript" charset="utf-8">
 
	$(document).ready(function() {
 
		rankFilter2(BB, RR);
	});
 
</script>

Re: fill ranking array with answers from previous question 3 years 7 months ago #59646

He Tony,

Did that already. How do access page 2 from you answer.

3) Place the following script in the source of one of the questions on page 1. Replace "AA" (line 7).
