Change answer to a question 2 years 1 week ago #60672

madopr OFFLINE Junior Lime Posts: 26 Karma: 0	What I need to do is this: If a question is answered, I need to hide the next question; but give a value to the answer of that second question depending of the answer of the first one. Is there a way to do this?

Ok, my first question is a numeric input. It's ID is 85348X27X184. My second question is a list (radio). The id of the second question is 85348X27X185 and the codes for each answer are 0, 1, 2, 3 and 4.
I inserted this code in the next section of my survey; but It doesn´t change the answer of my second question. Why?

<script>
$(document).ready(function() {
    if ({INSERTANS:85348X27X184} > 0)
    {
	if ({INSERTANS:85348X27X184} < 16)
	    {
		$('#answer85348X27X185').val(0);
	    }
	else if ({INSERTANS:85348X27X184} < 30)
	    {
		$('#answer85348X27X185').val(1);
	    }
	else if ({INSERTANS:85348X27X184} < 45)
	    {
		$('#answer85348X27X185').val(2);
	    }
	else if ({INSERTANS:85348X27X184} < 65)
	    {
		$('#answer85348X27X185').val(3);
	    }
	else if ({INSERTANS:85348X27X184} >= 65)
	    {
		$('#answer85348X27X185').val(4);
	    }
    }
});
</script>

You can't set a radio question that way, you need to set a "checked" attribute to true. I also think you're missing some quotes.

Assuming your questions are on different pages, try this:

<script type="text/javascript" charset="utf-8">
 
	$(document).ready(function() {
		if ('{INSERTANS:85348X27X184}' > 0)
		{
			if ('{INSERTANS:85348X27X184}' < 16)
			{
				$('#question184 input.radio[value="0"]').attr('checked', true);
			}
			else if ('{INSERTANS:85348X27X184}' < 30)
			{
				$('#question184 input.radio[value="1"]').attr('checked', true);
			}
			else if ('{INSERTANS:85348X27X184}' < 45)
			{
				$('#question184 input.radio[value="2"]').attr('checked', true);
			}
			else if ('{INSERTANS:85348X27X184}' < 65)
			{
				$('#question184 input.radio[value="3"]').attr('checked', true);
			}
			else if ('{INSERTANS:85348X27X184}' >= 65)
			{
				$('#question184 input.radio[value="4"]').attr('checked', true);
			}
		}
	});
 
</script>

Cheers,
Tony

Both questions 184 and 185 are in section 27; and I'm inserting this code in the first question of section 28. I use the alerts to check that the code of the correct option is reached; and it is; but the answer recorded for question 185 doesn't change.

<script>
$(document).ready(function() {
    if ({INSERTANS:85348X27X184} > 0)
    {
	if ({INSERTANS:85348X27X184} < 16)
	    {
		$('#question185 input.radio[value="0"]').attr('checked', true);
		alert("0");
	    }
	else if ({INSERTANS:85348X27X184} < 30)
	    {
		$('#question185 input.radio[value="1"]').attr('checked', true);
		alert("1");
	    }
	else if ({INSERTANS:85348X27X184} < 45)
	    {
		$('#question185 input.radio[value="2"]').attr('checked', true);
		alert("2");
	    }
	else if ({INSERTANS:85348X27X184} < 65)
	    {
		$('#question185 input.radio[value="3"]').attr('checked', true);
		alert("3");
	    }
	else if ({INSERTANS:85348X27X184} >= 65)
	    {
		$('#question185 input.radio[value="4"]').attr('checked', true);
		alert("4");
	    }
    }
});
</script>
