将具有循环引用的对象从服务器传递到客户端 Javascript，同时保持循环性 [英] Passing an object with circular references from server to client-side Javascript while retaining circularity

问题描述

我正在尝试将带有循环引用的对象从 node.js 服务器传递到客户端 javascript.

I'm trying to pass an object with circular references from node.js server to client-side javascript.

服务器(node.js):

Server (node.js):

var object = { circular: object }
//....
app.get('/', function(req, res){    
    res.render('index.jade', {object: object});
});

客户端 Jade/Javascript

Client-side Jade/Javascript

script var object = !{JSON.stringify(object)};

这里我得到了 object 包含循环引用的错误.

Here I get the error that object contains circular references.

以任何方式在客户端 javascript 中获取 object，使用^或不使用循环引用?

Any way to get the object in client-side javascript, with ^{or without} circular references?

推荐答案

Douglas Crockford 对此有一个解决方案，我之前已经成功地使用过:Cycle.js

Douglas Crockford has a solution for this that I have successfully used to solve this problem before: Cycle.js

而不是仅仅使用 stringify 和 parse 你会首先调用 decycle 并用 retrocycle

instead of just using stringify and parse you would first call decycle and restore with retrocycle

var jsonString = JSON.stringify(JSON.decycle(parent));
var restoredObject = JSON.retrocycle(JSON.parse(jsonString));
