Element type imagepicker

created 5 years ago

Hello.
I am trying to populate a 'choices' property (array) of a imagepicker element. Other elements that accept 'choices' use the Survey.ItemValue() to create elements but imagepicker extends the ItemValue() method as ImageItemValue().

Tracing (in question_imagepicker.ts) the population of a 'choices' array I see that an object of class ImageItemValue is instantiated from a call from Serialize.addclass() but there my understanding stops.

How do / can I instantiate an ImageItemValue object without invoking the code in jsonobjects.ts ?

Met vriendelijk groeten,
Max

Hello,

You can simply assign choices from a JSON array:

JavaScript
survey.getAllQuestions()[0].choices = [
            {
                "value": "lion",
                "imageLink": "https://surveyjs.io/Content/Images/examples/image-picker/lion.jpg"
            }, {
                "value": "giraffe",
                "imageLink": "https://surveyjs.io/Content/Images/examples/image-picker/giraffe.jpg"
            }, {
                "value": "panda",
                "imageLink": "https://surveyjs.io/Content/Images/examples/image-picker/panda.jpg"
            }, {
                "value": "camel",
                "imageLink": "https://surveyjs.io/Content/Images/examples/image-picker/camel.jpg"
            }
        ];

      Hello,

      Yes, you need to set the

      JSON
      "showLabel": true,

      property.
