hide question if prefilled

I prefill one answer using a URL like this

www.example/index.php/survey/index/sid/7...712544X99X2152=12345

Then I set the "always hide" option. Most of the time, this works, but sometimes the parameters are missing, so the answer is blank.

When it is blank, I want to unhide the question. I tried using a relevance equation of !is_empty(foo), but this seems to always hide the question and break recording of the answer in both cases.

I don't think you want to use relevance because the question should always be relevant, whether pre-populated or not.

Assuming it is a short-text question, try not using the "always hide" option, set up your survey to use JavaScript and add this to the question source:
<script type="text/javascript" charset="utf-8">	
	$(document).ready(function() {
		if($('#question{QID} input.text').val() == '') {
			$('#question{QID}.hide();
		}
	});	
</script>


Of course, this will also hide the question if a respondent answers it, moves on in the survey and then returns to the group later.

Hi,

Think i use 2 question.
First with hide settings prefilled by URL
Second : is_empty(FIRST)

ANd maybe a 2rd equation question type:
{FIRST.NAOK}{SECOND.NAOK}

Denis, this sounds like what I came up with.

I added a second question which is irrelevant when the first question is not empty.

I would like to hide the question if a textarea has been filled.

I'm using a question with a timer. It is the only question in the category.
I thought I had this working...
<script type="text/javascript" charset="utf-8">	
$(document).ready(function() {
  if($('#answer724821X200X1391').length > 0) {
			$('#question1391').hide();
alert($('#answer724821X200X1391').attr('value'));
  }
});
</script>

But it hides the question whether there is any text in the textarea or not. Any thoughts would be most appreciated. Thanks for maintaining such a great resource.

Try:
if($('#answer724821X200X1391').val() != '') {

That did the trick.

You know, I was trying that at one point, but I was trying to extend the if statement to handle a Default Answer.
So:
<script type="text/javascript" charset="utf-8">	
$(document).ready(function() {
if(($('#answer724821X200X1391').val() != '') or ($('#answer724821X200X1391').val() != 'Enter your response here.')) {
			$('#question1391').hide();
//alert($('#answer724821X200X1391').attr('value'));
  }
});
</script>

But, it didn't work. I just got rid of the Default answer and all is well.

For a default answer in a text question, try:

if($('#answer724821X200X1391').val() != '' && $('#answer724821X200X1391').val() != 'Enter your response here.') {

Is there documentation about how to do this for list or other non text questions? I would like to hide a question once it is answered. Thanks.
