It was late last night, so I forgot to mention I changed more then just the checkMax function in order to get it to work under LimeSurvey 3. In case anyone uses the search, this is the full code:
Code:
<script type="text/javascript" charset="utf-8">
$(document).ready(function(){// Maximun answersvar maxAnswers =2;// Identify this questionvar thisQuestion = $('#question{QID}');function checkMax(){
$('input[type="checkbox"]', thisQuestion).prop('disabled',false);if($("input:checked", thisQuestion).length >= maxAnswers){
$('input[type="checkbox"]', thisQuestion).not(':checked').prop('disabled',true);}}// Initial checkbox states
checkMax();// Listener on the checkboxes
$('input[type="checkbox"]', thisQuestion).on('change',function(e){
checkMax();});// Remove any "disabled" properties before submitting
$('#movenextbtn, #movesubmitbtn').bind('click',function(){
$('input[type="checkbox"]', thisQuestion).prop('disabled',false);});});</script>
Yes, you could target the buttons but I find that putting a listener on the form submit event also gets fired with the "Save and resume" function so data is always saved. Of course, it should be tested in individual workarounds (I am on my phone today so can't test).
