Count number of choices in a given question with dynamic number of choices.

Question

Hi!

I am trying to create a variable that counts the number of choices that currently exist in my question to make a loop, as I need to browse the possible choices to evaluate if they have been checked and set them to a specific value. The options are dynamic, as they appear depending on whether a YES was given in two different previous questions. I think I could also get this value if I use the If else option, but I wanted to know if there is a possibility to do it with only one line of code and not 6 or 7. Here below is my code for more context of what I tried (numSelectableOptions):

Qualtrics.SurveyEngine.addOnPageSubmit(function() {

var  x =	jQuery("#" + this.questionId + " input[type=text]").eq(0).val();
var  y=		jQuery("#" + this.questionId + " input[type=text]").eq(1).val();
var  z =	jQuery("#" + this.questionId + " input[type=text]").eq(2).val();

var numSelectableOptions = jQuery("#" + questionId + " .q-checkbox:not(.q-disabled)").length;

  // Loop through each item and check if it's not empty (embedded variable has a value)
  for (var i = 1; i <= numSelectableOptions; i++) {
    var itemValue = Qualtrics.SurveyEngine.getEmbeddedData("Inha" + i); // Get the embedded variable value for each item
	  // If the itemValue is not empty (not equal to an empty string)

	  if (itemValue == "other specify (1):") {
Qualtrics.SurveyEngine.setEmbeddedData("Inha"+i, x);	
    }
     if (itemValue == "other specify (2):") {
Qualtrics.SurveyEngine.setEmbeddedData("Inha"+i, y);	
    }
      if (itemValue == "other specify (3):") {
Qualtrics.SurveyEngine.setEmbeddedData("Inha"+i, z);	
    }
 }


});

And I also tried this:

var numChoices = jQuery('#' + questionId + ' .q-radio').length;

Nothing above works.

Thanks in advance for any suggestions.

Regards!

I close this post.I did not realize that I did not put this.questionID and left “questionID” only. It works fine.

I’m not clear on what you are trying to accomplish, but you can loop through the choices once and get what you need:

Qualtrics.SurveyEngine.addOnPageSubmit(function() {
	var qobj = this;
	jQuery.each(qobj.getChoices(), function(i, cid) {
		console.log("Loop",i); // the loop index)
		console.log("Choice Id",cid); // the choice id
		console.log("Value",qobj.getChoiceValue(cid)); //true if selected, otherwise false
		console.log("Displayed",qobj.getChoiceDisplayed(cid)); //true if displayed, otherwise false
		console.log("Text Value",qobj.getTextValue(cid)); //the associated text entry, blank if none
	});
});
