Automatically selecting an answer option even if it wasn't selected by the respondent

You could make C a default choice and it would be automatically selected. They would be able to deselect it.
Alternatively, you could use JS to select it in the addOnPageSubmit function.

Do you have a sample code? This is my first time programming in Qualtrics after transitioning from Confirmit.

Thanks.

This is my code. It's not working. 2 is the precode of the answer option that I want to auto-select.
Qualtrics.SurveyEngine.addOnPageSubmit(function()
{
/*Place your JavaScript here to run when the page is unloaded*/

var valQ8= "${q://QID9/SelectedChoicesRecode}";
var found = 0;
var arrQ8 = new Array();
arrQ8 = valQ8.split(",")

for(var i=0; i if (arrQ8[i]==2)
found = 1;
}
if (found = 0) { 
this.setChoiceValueByRecodeValue(2,true); 
}
});

Thanks!
