Tips for maintaining circular references when converting a JavaScript object to JSON string format

Currently, I am developing a filetree-like object that has a unique structure:

var myObject = {
    'name':'foo',
    'contains': {'thisObject': myObject,'parentObject': /* the object that contains the current object*/, 'foo':'bar'},
    'parent': /* the object that contains the current object*/
}

Although it may seem unconventional, there is a specific purpose behind this design.

This object is determined by the user and can potentially appear like this:

myObject.contains["foo"].contains["bar"].contains["biz"].contains["frt"]...

I am faced with the challenge of saving this structure to the user's computer. Currently, I have been using localStorage along with JSON.stringify(). However, this approach leads to JSON throwing a Circular Structure Error.

Is there a way to save this structure while still preserving the Circular Structure? Are there better alternatives than using localStorage/JSON?

Answer №1

Have you explored using a library that supports circular references?

A highly recommended option is DOJO.

According to its documentation:

var obj = {};
obj.me = obj;
var jsonWithCircularRef = dojox.json.ref.toJson(obj);
