Hi everybody,
first of all: I know this was asked before. I just can not make this code work (taken from www.limesurvey.org/de/forum/can-i-do-thi...pty-rows-of-a-matrix). Did something change there in the last updates? Unfortunately I'm not really fit in JavaScript, so please excuse if this is a stupid question. I have my questiongroup attached.

code in the description of the questiongroup:

<script type="text/javascript" charset="utf-8">
	$(document).ready(function() {
 
		// Hide all rows without a row label
		$('table.question tbody').each(function(i, el){
 
			var rowLabel = $('th:first', el).text().replace(/[\s\n\t]/g,'');
 
			if(rowLabel == '' || rowLabel == 'Newansweroption') {
				$(el).hide();
			}
		});
 
		// Fix up row background colours
		$('table.question tbody:visible tr').each(function(i, el){
			$(el).removeClass('array1, array2');
			if(i % 2 == 0) {
				$(el).addClass('array2');
			}
			else {
				$(el).addClass('array1');
			}
		});
 
	});
</script>

Second question is te corresponding matrix, rows are filled correctly by the {if} statement, but empty rows are shown nevertheless.

Thanks a lot for any input!
Steffen

The script above is for an array-numbers-checkbox question type.

For the plain array question type use this:

<script type="text/javascript" charset="utf-8">
	$(document).ready(function() {
 
		// Hide all rows without a row label
		$('table.question tr[id^="javatbd"]').each(function(i, el){
 
			var rowLabel = $('th:first', el).text().replace(/[\s\n\t]/g,'');
 
			if(rowLabel == '') {
				$(el).hide();
			}
		});
 
		// Fix up row background colours
		$('table.question tr[id^="javatbd"]:visible').each(function(i, el){
			$(el).removeClass('array1, array2');
			if(i % 2 == 0) {
				$(el).addClass('array2');
			}
			else {
				$(el).addClass('array1');
			}
		});
 
	});
</script>

Cheers,
Tony
