How can i set "side-by-side" question type variation "SBSMatrix" values using the QX API?

Question

I have a question of question type “side-by-side” I’d like to set the values for. The question looks in the UI like this.

Via the question object I can get the question info. It contains the question type (QuestionType “SBS”) and variation (Selector “SBSMatrix”) which allow me to identify this question type variation as such one.

The challenges I have right now:

- How can I get meta data about the types of the column values (first column is string type, second column is integer type)? This is required to add conditional business logic based on actual question type variation.

- What Qualtrics API (q.setChoice<something>) can I use in general to set values for this question type variation in survey preview mode a reliable way (means with a unique identifier for specific matrix cells)? This is required to set the values in a reliable way.

@Tom_1842The way how rows and rows need to be indexed is like usual rows via choices. columns via answers is different from the usual pattern.I’d assume that for other side by side matrices anddata types the id will just lack “~TEXT” means “QR~QID#1~9~1”.

I was having trouble setting values for Side-by-Side with setChoiceValue, but setting values by the Id of the input with jQuery works. For a Side-by-Side with 2 columns, 1 Column Answer per column, and both set to Open Ended Text, try adding to the below to the OnReady of the question’s JavaScript.

The Id of an input will look like QR~QID29#2~3~1~TEXT where:

#2 is the column number

~3 is the row number

~1 is the Column Answer number

var qid = this.questionId;
var input1 = document.getElementById("QR~"+qid+"#1~2~1~TEXT");
jQuery(input1).val("Text 1");

var input2 = document.getElementById("QR~"+qid+"#2~3~1~TEXT");
jQuery(input2).val("Text 2");
