Populate coded values via code only (ignoring text)

A proposal / question

It would be great if the logic of the surveys would be able to operate on coded choices only (if coded) and ignore the text labels.

What is the current behavior?

I’m not sure (yet how the filtering & conditions work), but for populating/ setting data, it only works if both code and text match.

A simple example of what I mean.
let’s say I have a question like :

{
    type: "radiogroup",
    name: "car",
    title: "What car are you driving?",
    isRequired: true,
    choices: [
        {'code':1, "text":"Ford"},
        {'code':2, "text":"BMW"},
        {'code':3, "text":"Ziguli"}
    ]
}

right now, in order to set the value, one would need to have it like:

survey.data = {car: {code:1,text:'Ford'}};

What is the expected behavior?

I think it would be logical if only this would be enough:

survey.data = {car:1};

If the choices are coded, using codes will resolve numerous issues like

• simplicity
• translation issues (having texts in various languages needs separate attention & a layer of management)
• Changeability. Mostly you need to change the label / text only. What if you change the form coded text and you have some values stored with a different text?
• less data to store. Storing {car:1} takes much less space than {car: {code:1,text:'Ford'}} Imagine if you would have some code in the text labels (eg html).

Thank you for a cool library!

@TonisOrmisson You should use value in expressions and it means that {haveKids}=5 works perfectly. choices : [1, 2] is the same as choices : [{value: 1}, {value: 2}] and text is optional and surveyjs uses it for displaying in UI only. Adding text as: choices : [{value: 1, text: "first year"}, {value: 2, text: "second year"}] doesn’t change the way it works in expression.

Thank you, Andrew

@andrewtelnov thank you!

You are completely right. And seems the setting also works perfectly. It seems that my mistake was wrongly using code instead of value. 🤦‍♂️

excellent work guys
