将自定义javascript对象转换为json

Convert custom javascript object to json

我试图将javascript中的自定义对象转换为json字符串，但我一直收到循环引用错误。有没有一种方法可以使用JSON.stringify，或者我必须自己手动创建字符串？

这是我的代码：

function configuration(comments, instances, connections)
{
    this.comments = comments;
    this.instances = instances;
    this.connections = connections;
    return this;
}
function instance(id, type)
{
    this.id = id;
    this.type = type;
    return this;
}
function connection(from, to)
{
    this.from = from;
    this.to = to;
    return this;
}
function from(id, property, index)
{
    this.id = id;
    this.property = property;
    this.index = index;
    return this;
}
function to(id, property, index)
{
    this.id = id;
    this.property = property;
    this.index = index;
    return this;
}

var comments = "this is a test comment";
var instances = [];
var connections = [];
connections.push(connection(from("34hvd","inputs", 0), to("dheb3", "outputs", 0)));
instances.push(instance("34vd", "tee"));
instances.push(instance("dheb2", "average"));
var config = configuration(comments, instances, connections);
JSON.stringify(config);

正如您所看到的，我正在尝试字符串化配置对象，它包含注释（字符串）、实例（实例对象数组）和连接（连接对象数组）。

如果有更好的方法，请告诉我。感谢

如果在调用函数时不使用new，则返回的this将引用window，即创建循环引用的内容。

这将工作

connections.push(new connection(new from("34hvd","inputs", 0), new to("dheb3", "outputs", 0)));
instances.push(new instance("34vd", "tee"));
instances.push(new instance("dheb2", "average"));
var config = new configuration(comments, instances, connections);
console.log(config)
