circumvent ERROR Converting circular structure to JSON when doing JSON.stringify()?

rated 0 times [ 57] [ 2] / answers: 1 / hits: 25112 / 13 Years ago, wed, march 23, 2011, 12:00:00

For debugging I want to serialize javascript objects with JSON.stringify(myobject). But this gives:

TypeError: Converting circular structure to JSON

Is there a way to prevent this, by for instance pruning the output tree?

Some more background:

I want to collect some data on different objects and see what is going on, and why a feature works for one situation but not for another. By comparing outputs I hope to be able to find differences which explains why it is not working in another situation.
I'm using jquery and my debug horse is called chrome. If there are better alternatives for doing this type of debugging activities I'm also very much interested!

Cheers,
jeroen.

JSON.stringify(obj) does not support circular referencing such as:

var car = {}

car.myself = car;

JSON.stringify(car);

However dojox.json.ref does support circular referencing, if you wanted to explore another option.

However if your purposes are strictly to debug, I'd suggest using the built in browser debugger such as Chrome's, IE's or Firebug(for firefox).
