i have JSON data and I want to convert this data in to javacript object

"Convert" (from string) is called "parse".. Use `JSON.parse(JSONString);` — UltraInstinct, Jun 26 '12 at 08:13

Use JSON.parse^[MDN]. It was introduced in ECMAScript 5 and is therefore not supported by <=IE7. You can find a JSON library to fill in support for older browsers, or if you use jQuery you can use $.parseJSON^{[jQuery docs]}.

var str = '"data": [ { "name": "JoongBum Lee", "id": "526210623" }, { "name": "\uc774\uc778\uaddc", "id": "560021193" }, { "name": "SunAh Han", "id": "589325702" } ] }';
var obj = JSON.parse(str);

sorry but error occurs document.getelementbyld is null or not object – Suk Kyu Sun Jun 27 '12 at 04:31
@SukKyuSun That error must be in some other section of your code, because parsing JSON has nothing to do with the `document.getElementById` function. – Peter Olson Jun 27 '12 at 06:40

var dataString = "{/* SOMETHING */}"
var obj = eval("(" + dataString + ")");

This would work, but not recommend. – epascarello Jun 26 '12 at 16:24
sure JSON.parse(str) is better, but not supported by older browsers. – Flavien Volken Jun 27 '12 at 06:46
