如何从DOJO中的Json数组中获取数据？

Question

我有一个小问题：

如果我有一个JSON数组：

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

如何获取["res_name"]索引的数据？

我警告data['res_name']结果未定义。

感谢您的任何建议！

您需要首先从JSON数组解析Javascript对象。

//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']);

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