How to deserializing a JSON into a JavaScript object

0 votes

I have a string in a Java server application that is accessed using AJAX. It looks something like the following:

var json = [{
    "adjacencies": [
        {
          "nodeTo": "graphnode2",
          "nodeFrom": "graphnode1",
          "data": {
            "$color": "#557EAA"
          }
        }
    ],
    "data": {
      "$color": "#EBB056",
      "$type": "triangle",
      "$dim": 9
    },
    "id": "graphnode1",
    "name": "graphnode1"
},{
    "adjacencies": [],
    "data": {
      "$color": "#EBB056",
      "$type": "triangle",
      "$dim": 9
    },
    "id": "graphnode2",
    "name": "graphnode2"
}];

When the string gets pulled from the server, is there an easy way to turn this into a living JavaScript object (or array)? Or do I have to manually split the string and build my object manually?

Hello @kartik,

To collect all item of an array and return a json object

collectData: function (arrayElements) {

        var main = [];

        for (var i = 0; i < arrayElements.length; i++) {
            var data = {};
            this.e = arrayElements[i];            
            data.text = arrayElements[i].text;
            data.val = arrayElements[i].value;
            main[i] = data;
        }
        return main;
    },

TO parse the same data we go through like this

dummyParse: function (json) {       
        var o = JSON.parse(json); //conerted the string into JSON object        
        $.each(o, function () {
            inner = this;
            $.each(inner, function (index) {
                alert(this.text)
            });
        });

}

Hope it helps!!
Thank you!!
