Auto next on single question

To make single questions automatically go to next question when an answer option has been selected, put the script on questionnaire's javascript of editor

AnswerSheet.bind('afterShowPage', function(ev, as) {
	//check current is Single Question
	if (as.questions.length != 1) return;
	var q = as.questions[0];
	if (q.type != 1) return;
	//auto next
	q.answerOptions.bind('selectionChanged', function() {
		var ao = this.getAnswer()[0];
		if (!ao || ao.open) return; //ignore Open answer
		if (typeof as.onTriggerEnterKey === "function") as.onTriggerEnterKey(q);
		else as.moveToNextPage(); //backwards compatible
	});
});
