Javascript to filter values from embedded field and then select random item | XM Community
Skip to main content
Kia ora koutou, hello everyone!



I have an embedded field 'colour_selection' which is populated with answers from a multiple answer questions in the survey flow. I would like to use Javascript to filter out specific answers, and then from the filtered list take a random answer to store back in to an embedded field to pipe in to a following question.



(I would have loved to do this using a loop and merge, but it seems like it's not possible to exclude answers easily).



I have limited Javascript ability, but have managed to get this code to work fine here https://jsfiddle.net/1etL6axn/



However when I try to run this in Qualtrics I'm getting a console error "colourSelection.filter is not a function".



I get an "access denied" error when I try to post code here, so here is a screenshot. And I've attached the qsf.



!





Is this a limitation within Qualtrics? Should I try to find a solution using JQuery instead? Have I missed something unique to Qualtrics to make this work?

Thanks in advance

Dan
Your issue is that colourSelection is a string, not an array. The first line should be:

```

var colourSelection = "${e://Field/colour_selection}".split(", ");

```
That is exactly what the problem was. Thank you so much for your help Tom.
