具有向JSON添加属性的KineticJS对象 [英] KineticJS object with added property to JSON

问题描述

我正在尝试将KineticJS对象(具有一个添加的属性)序列化为JSON，但是如果我调用JSON.stringify(test);，它将仅返回KineticJS对象的JSON表示而没有我的添加属性.有人知道，请问哪里可能有问题?

I am trying to serialize KineticJS object (with one added property) to JSON, but if I call the JSON.stringify(test);, it returns only JSON representation of KineticJS object without my added property. Does anybody know, where could be a problem, please?

 test = new Kinetic.Line(
                {
                    points : [ 29, 30, 31, 32 ],
                    stroke : 'black',
                    strokeWidth : 2,
                    lineJoin : 'round',
                    id : '#line'
                });
 test.obj = "my own property";
 JSON.stringify(test);

返回

{"attrs":{"points":[{"x":29,"y":30},{"x":31,"y":32}],"stroke":"black","strokeWidth":2,"lineJoin":"round","id":"#line"},
"nodeType":"Shape","shapeType":"Line"}"

但是我还需要有关test.obj的信息.

But I need also information about test.obj..

推荐答案

您可以这样做:

var test = new Object();

test.kinetic = new Kinetic.Line(
                {
                    points : [ 29, 30, 31, 32 ],
                    stroke : 'black',
                    strokeWidth : 2,
                    lineJoin : 'round',
                    id : '#line'
                });
 test.obj = "my own property";
 console.log(JSON.stringify(test));
