jQuery解析xhr.responseText [英] Jquery parse xhr.responseText

问题描述

var data  = xhr.responseText;

当我输出此console.log(xhr.responseText)时.以下是我的输出

When I output this console.log(xhr.responseText). Below is my output

["{id:1,name\":\"JOHN\",\"city\":\"null\"}"
,"{\"id\":2,\"name\":\"MICHEAL\,\"city\":\"null\"}"]

如何获取id，name.我尝试这样data.id，但出现此错误

How do I get id, name. I tried like this data.id but I get this error

jquery JSON.parse:数据意外结束.

jquery JSON.parse: unexpected end of data.

更新

我将代码点火器与数据映射器一起使用，因此我的数据映射器给出了json响应.你知道吗，我该怎么解决.

I am using code igniter with data mapper so my data mapper is giving that json response. Do you know, how I can resolve it.

推荐答案

您已经被告知注释中存在问题:服务器生成的JSON无效.您可能没有使用库对JSON进行编码，永远不要手动对其进行编码.

You've already been told what the problem is in the comments: the JSON generated by the server is invalid. You are probably not using a library to encode your JSON, don't ever encode it by hand.

您的JSON可能看起来应如下所示(打印精美时) http://jsfiddle.net/7FKWr/

Your JSON should probably look like the following (when pretty printed) http://jsfiddle.net/7FKWr/

[
  {"id": 1, "name": "JOHN", "city": null},
  {"id": 2, "name": "MICHEAL", "city": null}
]
