Using JavaScript with Embedded Data and/or selected choices.

Hi @AnthonyR, That is great info. I searched forever through the Document Object Model to find the embedded data fields. Any idea how to set embedded data? Also, I assume that we can use the other piped text types to get other data (ie ${q://QID10/ChoiceTextEntryValue} ). Thanks!

@rettweber Absolutely, anything that can be piped, can be used in JavaScript this way. As for setting embedded data, you can use: Qualtrics.SurveyEngine.setEmbeddedData( 'embeddedDataVariable', value ); Just make sure that that embedded data element exists in your survey flow before you set it.

Hi @AnthonyR , I was testing changing the embedded data and I am having issues getting the code to work. Although I can retreive embedded data, Yay! I cannot seem to get a selected choice from a question and I can't seem to set the embedded data value. Here is the code I was using ... I set test_status = require in survey flow as first element. QID5 is a single select dropdown multiple choice question. The code is placed in the question Javascript section. ! The code runs when the QID5 option is changed. the console shows element1 = empty (actually not sure if null, empty, or space) the console shows element2 = require the console shows element3 = require I am sure I am doing something silly. I can get and change the information using the document object model, but I would prefer to be more direct (ie using Qualtrics functions) as the DOM could change. Thanks, Rett P.S. Sorry I had to include an image of the code. Whenever I tried to include the code I received an access error. I have a call in to Qualtrics support to see what was going on.

@rettweber Ahh this is a classic case of order of operations. Qualtrics populates the piped text on page load, not on execution. So essentially your code once the page loads and it executes is: Qualtrics.SurveyEngine.addOnReady(function(){ document.getElementById("QR~QID5").onChange = function(element){ var element1 = ""; var element2 = "require"; console.log(element1); console.log(element2); Qualtrics.SurveyEngine.setEmbeddedData('test_status', 'changed value'); var element3 = "require"; console.log(element3); document.getElementById("QR~QID4").value = element1; } }); If you check the embedded data on the next page it will have been updated. And if you want the answers to a question on the same page, you will have to parse through the DOM. FYI: when including code, make sure to highlight all of it, and format it as code using the format button at the top of the edit window.

How do I refer to a choice text in a loop & merge so that it always refers to the current loop? I can refer to the first loop's choice as ${q://1_QID88/ChoiceGroup/SelectedChoices} And I can refer to the number of the current loop as ${lm://CurrentLoopNumber} But nesting the loop number inside the survey question name as below didn't work either in piped text or Javascript "${q://${lm://CurrentLoopNumber}_QID1/ChoiceGroup/SelectedChoices}"

@nathanbos - If you have a new question you should start a new discussion rather than adding to an old one. As to your question, refer to the current loop by leaving out the loop number. For example: ``` ${q://QID88/ChoiceGroup/SelectedChoices} ```

Tom- thank you! I will start a new discussion next time.
