I've written the following code to read data from json file and draw a graph. now I want to get the data from user through input fields and update the json with new values. I wrote the code to copy the value and made it accessible outside the scope, I just wonder how to update the existent json with the new values.
json looks like this:
{
"nodes" : [
{ "id": 1, "label": "End Product", "level": 0 },
{ "id": 2, "label": "A 1", "level": 1 },
{ "id": 3, "label": "A 2", "level": 1 },
{ "id": 4, "label": "A 3", "level": 1 },
{ "id": 5, "label": "B 1", "level": 2 },
{ "id": 6, "label": "C 1", "level": 3 },
{ "id": 7, "label": "B 2", "level": 2 },
{ "id": 8, "label": "B 3", "level": 2 }
],
"edges" : [
{ "from": 1, "to": 2 },
{ "from": 1, "to": 3 },
{ "from": 1, "to": 4 },
{ "from": 2, "to": 5 },
{ "from": 5, "to": 6 },
{ "from": 3, "to": 7 },
{ "from": 4, "to": 8 }
]
}
var app = angular.module('bomApp', ['bomGraph']);
app.controller('bomController', ['$scope', 'appService', '$rootScope', function ($scope, appService, $rootScope) {

appService.get().then(function (promise) {

};
});
};
$scope.newNode = {
