Hi there,
I am trying to adjust some Javascript to set the default radio button in an array question. I'm not familiar with Javascript, so don't know what I'm doing wrong. Here is my code:
What kinds of support and resources would {orgname} prefer to receive through the project?
<script type="text/javascript" charset="utf-8">
$(document).ready(function() {
 
$('#question{QID} tr[id^="javatbd"]').each(function(i) {
if($('#question{QID} input.radio:checked').length == 0) {	
document.getElementById('answer{SGQ}-A3').checked = 'checked';
})
})
 
});
</script>

I've managed to get it to work with the following code, but would like to get rid of the repetition. Anyone know the way to make it work for all sub-questions with one line of code?
What kinds of support and resources would {orgname} prefer to receive through the project?
 
<script type="text/javascript" charset="utf-8">
$(document).ready(function() {
if($('#question{QID} input.radio:checked').length == 0) {	
 
document.getElementById('answer{SGQ}SQ001-A3').checked = 'checked';
document.getElementById('answer{SGQ}SQ002-A3').checked = 'checked';
document.getElementById('answer{SGQ}SQ003-A3').checked = 'checked';
document.getElementById('answer{SGQ}SQ004-A3').checked = 'checked';
document.getElementById('answer{SGQ}SQ005-A3').checked = 'checked';
document.getElementById('answer{SGQ}SQ006-A3').checked = 'checked';
document.getElementById('answer{SGQ}SQ007-A3').checked = 'checked';
document.getElementById('answer{SGQ}SQ008-A3').checked = 'checked';
 
}
 
});
</script>

Try this:

<script type="text/javascript" charset="utf-8">
	$(document).ready(function() {
 
		$('#question{QID} tr[id^="javatbd"]').each(function(i) {
			if($('input.radio:checked', this).length == 0) {
				var radio = $('input.radio[value="A3"]', this);			
				$(radio).prop('checked', true);
				checkconditions($(radio).val(), $(radio).attr('name'), 'radio');
			}
		});
 
	});
</script>

Cheers,

Hi! Have a nice day!
I was in trouble about this piece of javascript code that's perfectly functioning on 2.05 version but NOT under 3.04

The script I try is:
<script type="text/javascript" charset="utf-8">

$(document).ready(function(){

// Identify this question ID
var qID = {QID};

// Loop through the rows and check the first radio if none are already checked
$('#question'+qID+' table.question tbody tr').each(function(i) {
if($('input.radio:checked', this).length == 0) {
$('input.radio:eq(0)', this).attr('checked', true);
}
});
});

</script>

Of course I try with your proposal too, but the effect in none in both cases: no checked radio button!

What is wrong or mistake ?

Thanks in advance for any suggestion ...

This script will set the first column as defaults in 3.4.x:

<script type="text/javascript" charset="utf-8">
	$(document).ready(function(){
 
		// Identify this question ID
		var qID = {QID};
 
		// Loop through the rows and check the first radio if none are already checked
		$('#question'+qID+' .table-array-radio tr.answers-list').each(function(i) {
			if($('input[type="radio"]:checked', this).length == 0) {
				$('input[type="radio"]:eq(0)', this).trigger('click');
			}
		});
	});
</script>
