Set Text Box response from embedded data

You don’t need JavaScript to do this.  In your text entry question click ‘Default choices’ then pick  Embedded Data Field → GRP_ID.

That works great! 

However, if I wanted to do some transformation on the embedded data before setting the value, I could generate the final value with javascript and then how would I set this calculated value as the default value?

Like this:

Qualtrics.SurveyEngine.addOnload(function() {
  var mystring = "string value";
  jQuery("#"+this.questionId+" .InputText").val(mystring);
});

You can also try writing it as,

jQuery(this).input(type=”text”).val(Qualtrics.getEmbeddedData(‘GRP_ID’))
