When you have a long list of multiple choice options, it would be nice to have an option "Select All". While we don't currently have a configuration option to enable this, we do have a simple workaround.
Here's a short video review of the above:
HICS - Multiple Choice Select All Workaround from Hosted in Canada Surveys on Vimeo.
Copy and paste the following script as described in Step #4 above:
$(document).on('ready pjax:complete',function() {
// Identify this question
var thisQuestion = $('#question{QID}');
// Initial states
if($('input[type="checkbox"]:last', thisQuestion).is(':checked')) {
$('input[type="checkbox"]', thisQuestion).not(':last').prop('checked', true).prop('disabled', true);
}
// Listener on the last checkbox
$('input[type="checkbox"]:last', thisQuestion).on('change', function(e) {
if($(this).is(':checked')) {
$('input[type="checkbox"]', thisQuestion).not(this).prop('checked', true).prop('disabled', true);
}
else {
$('input[type="checkbox"]', thisQuestion).not(this).prop('checked', false).prop('disabled', false);
}
// Fire Expression Manager
$('input[type="checkbox"]', thisQuestion).not(this).each(function(i) {
checkconditions(this.value, this.name, this.type);
});
});
// Re-enable checkboxes so data gets stored
$('#moveprevbtn, #movenextbtn, #movesubmitbtn').on('click', function(){
$('input[type="checkbox"]', thisQuestion).prop('disabled', false);
});
});
