I have a small question :

If I have a JSON array:

{
"cate_user_res_id": "4",
"from": "url",
"mimetype": "image/jpeg",
"ext": "jpg",
"res_name": ".jpg",
"user_id": "1",
"file_size": 55966,
"created": "2011-12-19 03:29:45",
"type": "i"
}

How can i get data of ["res_name"] index?

I alert data['res_name'] it result undefined.

Thanks for any suggestion!

You need to parse to Javascript object first from the JSON array.

//var data = JSON.parse("<JSON string>");
var data = JSON.parse('{ "res_name" : " stackoverflow" }');

//Then you can get your value easily.
console.log(data.res_name);
console.log(data['res_name']);

Check this tutorial, would be helpful: http://geochalkboard.wordpress./2009/08/03/reading-json-data-with-dojo/

var obj = dojo.fromJson(json);
console.log(obj.res_name);
