What is the best method for breaking down this JSON data into distinct 'objects'?

I am struggling with deserializing JSON data into multiple instances of an object I have defined. Here is how the object is structured:

function Question_Value__c () {
    this.Id=null;
    this.Name=null;
    this.Question__c=null;
    this.Order__c=null;
}

The JSON data I am trying to deserialize looks like this:

[{"id":"a0Dd000000RTVsAEAX","name":"ee"},{"id":"a0Dd000000RTVsAEAX","name":"ee"},{"id":"a0Dd000000RTVsAEAX","name":"ee"},{"id":"a0Dd000000RTVsAEAX","name":"ee"},{"id":"a0Dd000000RTVsAEAX","name":"ee"}]

This is what I've tried so far:

allValues = new Array(new Question_Value__c());
$(returnedJSON).each(function() {
    allValues.push($(this));
console.log(allValues[0].id);
});

Any guidance on how to properly deserialize and work with JSON in JavaScript would be greatly appreciated, as I am still relatively new to this area.

Answer №1

Firstly, ensure that you include actual " in your JSON string. It is incorrect to encode these characters using ", as that would be appropriate for HTML encoding.

Furthermore, if you wish to fill your Question_Value_c objects with data, modify your constructor function like so:

   function Question_Value__c(data) {
       $.extend(this, data); // consider using $.extend
   }

Afterwards, perform the following steps (keep in mind that your objects are missing Question__c and Order__c properties):

  var json = '[{"id":"a0Dd000000RTVsAEAX","name":"ee"},{"id":"a0Dd000000RTVsAEAX","name":"ee"},{"id":"a0Dd000000RTVsAEAX","name":"ee"},{"id":"a0Dd000000RTVsAEAX","name":"ee"},{"id":"a0Dd000000RTVsAEAX","name":"ee"}]',
       allValues = [];

   $.each($.parseJSON(json), (function () {
       allValues.push(new Question_Value__c(this));
   }));

   console.log(allValues);
