Qualtrics: Transform piped variable using javascript and display it in text?

Question

Let there be a piped variable in qualtrics (a variable holding values recalled from a previous input by a survey respondent), how do I transform it to lower-case before displaying it?

There is the java-script function .toLowerCase(); but how do I change a variable in the qualtrics custom javascript and pipe it back into a survey text?

This link explains how to use piped variables in javascript. Say I define a new variable in javascript like this

// my piped variable is ${q://QID12/ChoiceGroup/SelectedAnswers}"
var selectedChoice = "${q://QID12/ChoiceGroup/SelectedAnswers}";
var selectedChoiceLower = selectedChoice.toLowerCase();

How to pipe selectedChoiceLower back into a question text?

Any ideas?

Use the setEmbeddedData() function to assign selectedChoiceLower to a new or existing embedded data variable (see documentation). Then, you can use the embedded field variable in a later question.

javascript: setEmbeddedData('lower', selectedChoiceLower);

embedded field code: ${e://Fields/lower}

warning: putting user-generated text into your javascript is very dangerous! Qualtrics does not do any escaping. If a user puts a ' or " in their text, it will be put directly into the javascript and probably break your code. Code injection is also possible. See this question for more details.

What doesn't work? For what? And what happens instead? – octern Feb 12 '15 at 14:39
