Is there any possibility to have JSON.stringify preserve functions?

Question

Take this object:

x = {
 \"key1\": \"xxx\",
 \"key2\": function(){return this.key1}
}

If I do this:

y = JSON.parse( JSON.st         


        

Answer 1

Technically this is not JSON, I can also hardly imagine why would you want to do this, but try the following hack:

x.key2 = x.key2.toString();
JSON.stringify(x)  //"{"key1":"xxx","key2":"function (){return this.key1}"}"

Of course the first line can be automated by iterating recursively over the object. Reverse operation is harder - function is only a string, eval will work, but you have to guess whether a given key contains a stringified function code or not.
