How to read json file inside Vuforia Studio

[Aditya1702]

Hi everyone,

I have a json file which has attribute values of a widget in key value pair for eg.

"attributes": {

                "twx-widget": "",

                "widget-id": "p2a",

                "widget-name": "p2a",

                "is-widget-container": "true",

                "src": "Uploaded/pin.pvz",

                "scale": "0.5",

                "x": 0.44480000000000003,

                "y": 0.6587000000000001,

                "z": 0.603,

                "rx": "0",

                "ry": "0",

                "rz": "0"

            },

"attributes": {

                "twx-widget": "",

                "widget-id": "p2b",

                "widget-name": "p2b",

                "is-widget-container": "true",

                "src": "Uploaded/pin.pvz",

                "scale": "0.5",

                "x": 0.44480000000000003,

                "y": 0.6587000000000001,

                "z": 0.611,

                "rx": "0",

                "ry": "0",

                "rz": "0"

            }

How can I assign this value to a widget in Vuforia Studio?

Thanks in advance.

Hi @VladimirN ,

I tried the link you provided but was not able to read the data from the json file.

Can you please explain in more detail about how can I fetch data from json file and change the widget values.

Thanks in advance.

Hi @Aditya1702 ,

I woud think - when the data is assigned to the scope variable myJson

then you can access it 

$scope.myJson= data

e.g. you want to access the x,y and z value

but first to correct that print should be an array so let say the variable name is then $scope.myJsonArray ...

$scope.myJsonArray=["attributes": {
                "twx-widget": "",
                "widget-id": "p2a",
                "widget-name": "p2a",
                "is-widget-container": "true",
                "src": "Uploaded/pin.pvz",
                "scale": "0.5",
                "x": 0.44480000000000003,
                "y": 0.6587000000000001,
                "z": 0.603,
                "rx": "0",
                "ry": "0",
                "rz": "0"
            },
"attributes": {
                "twx-widget": "",
                "widget-id": "p2b",
                "widget-name": "p2b",
                "is-widget-container": "true",
                "src": "Uploaded/pin.pvz",
                "scale": "0.5",
                "x": 0.44480000000000003,
                "y": 0.6587000000000001,
                "z": 0.611,
                "rx": "0",
                "ry": "0",
                "rz": "0"
            }]

so now when we want to access the x for the first element and set it to value e.g.

$scope.myJsonArray[0]['attributes'].x=0.46
//or 
$scope.myJsonArray[0].attributes.x=0.46
//or 
$scope.myJsonArray[0]['attributes']['x']=0.46

and let say to set Y valuel of the second element it should be  something like that :

$scope.myJsonArray[1]['attributes'].y=0.77
//or 
$scope.myJsonArray[1].attributes.y=0.77
//or 
$scope.myJsonArray[1]['attributes']['y']=0.77
