Pre-set answer in radioboxes array

5 years 11 months ago #57590 by martijntk
Regarding a social network analysis questionnaire, I would like to use an array-like approach

name 1
name 2
name 3
name 300

The option "never" should be pre-set standard, because it is likely that respondents know a few of the others and will have to select only a few names. Is it possible to have the radioboxes under "NEVER" all checked standard?

If you're using a simple array with radio buttons, the following should work.

Set up your survey to use JavaScript and place the following script in the source of the array question. Replace "QQ" with the array question ID.

The script will loop through all rows and if no checked radios are found, the last one in that row will be checked.
<script type="text/javascript" charset="utf-8">
	$(document).ready(function() {
		var qID = QQ;
		$('#question'+qID+' table.question tbody tr').each(function(i) { 
			if($('', this).length < 1) {
				$('', this).attr('checked', true);
