convert javascript object into json string apart from using JSON.Stringify

Question

hii i am trying to convert a javascript object to JSON string . are there any alternative apart from JSON.stringify() ?? cause the method is giving error in IE 7 .... its works perfect in IE8 onwards and other browsers . so just wanna know are there any ways to convert a javascript object such as :

var Schedules = new Object();
Schedules.ProjectTypeID = "abc";
Schedules.ProjectID = "123";
Schedules.ScheduleID = "12345";
Schedules.MilestoneID = "milestone1";

and it should give a json string something like

{"ProjectTypeID":"abc","ProjectID":"123","ScheduleID":"12345","MilestoneID":"milestone1"}

Answer 1

The reason why you're getting the error in IE7 is because the JSON library that has the .stringify() function is not inherent in IE7's JS model (correct me if I'm mistaken).

So what you want to do is to include the json2.js file that Kon mentioned in his answer above when you're in an IE7 environment (or other incompatible envi).

You could just load it anyway, I guess. I'm pretty sure it won't cause collisions.

Answer 2

use the json2.js from this github: https://github.com/douglascrockford/JSON-js

Hope this helps.

Not sure this helps you, but you could just build it in JSON format from the beginning:

var Schedules = {
  ProjectTypeID : "abc",
  ProjectID : "123",
  ScheduleID : "12345",
  MilestoneID : "milestone1"
}
