Prettify JSON Array in JavaScript

I'm working on a project that will be used to help analyse and understand JSON arrays by future developers of a platform. I'm referencing Facebook's brilliant Graph Explorer page, seen here, and want to output our array in a prettified, correctly tab indented and line breaker array, just as it does on the explorer.

The arrays are outputted to a textarea , and because of this I think I'm running into issues with the line breaking and tabbing. I've also tried using the prettify library, but with no luck.

Example:

{"outcome" : "success", "result" : {"name" : "messaging-sockets", "default-interface" : "external", "include" : [], "socket-binding" : {"messaging" : {"name" : "messaging", "interface" : null, "port" : 5445, "fixed-port" : null, "multicast-address" : null, "multicast-port" : null}, "messaging-throughput" : {"name" : "messaging-throughput", "interface" : null, "port" : 5455, "fixed-port" : null, "multicast-address" : null, "multicast-port" : null}}}, "compensating-operation" : null}

To:

{
   "outcome":"success",
   "result":{
      "name":"messaging-sockets",
      "default-interface":"external",
      "include":[

      ],
      "socket-binding":{
         "messaging":{
            "name":"messaging",
            "interface":null,
            "port":5445,
            "fixed-port":null,
            "multicast-address":null,
            "multicast-port":null
         },
         "messaging-throughput":{
            "name":"messaging-throughput",
            "interface":null,
            "port":5455,
            "fixed-port":null,
            "multicast-address":null,
            "multicast-port":null
         }
      }
   },
   "compensating-operation":null
}

You may use JSON.stringify:

JSON.stringify(jsonobj,null,'t')

See the demo.

UPDATE: If you don't have jsonobj ,but have json string,then before using stringify function,convert json string to json object by this line:

jsonobj = JSON.parse(jsonstring);

试试这个解决方案，我也在我的项目中使用了这个
