JSON to string variable dump

Question

Is there a quick function to convert JSON objects received via jQuery getJSON to a string variable dump  for tracing debugging purposes

User · Answer

i personally use the jquery dump plugin alot to dump objects, its a bit similar to php's print_r() function Basic usage:

var obj = {
            hubba: "Some string...",
            bubba: 12.5,
            dubba: ["One", "Two", "Three"]
        }
$("#dump").append($.dump(obj));
/* will return:
Object { 
     hubba: "Some string..."
     bubba: 12.5
     dubba: Array ( 
          0 => "One"
          1 => "Two"
          2 => "Three"
     )
}
*/

Its very human readable, i also recommend this site http://json.parser.online.fr/ for creating/parsing/reading json, because it has nice colors

You can use console log   in Firebug or Chrome to get a good object view here  like this     getJSON  my json   function data      console log data         If you just want to view the string  look at the Resource view in Chrome or the Net view in Firebug to see the actual string response from the server  no need to convert it   you received it this way    If you want to take that string and break it down for easy viewing  there s an excellent tool here  http   json parser online fr

Yes  JSON stringify  can be found here  it s included in Firefox 3 5 4 and above   A JSON stringifier goes in the opposite direction  converting JavaScript data structures into JSON text  JSON does not support cyclic data structures  so be careful to not give cyclical structures to the JSON stringifier  https   web archive org web 20100611210643 http   www json org js html  var myJSONText   JSON stringify myObject  replacer
