阅读JSON Ajax响应？

Question

I have an ajax response from my server. Example below:

{"user_id":"93","status_message":"Cool Status","timestamp":"1305648702"}

I tried reading the response using:

var json = eval(response);
var userid = json.user_id;

The above does not seem to work though. Any ideas.

Answer 1

You should use the JSON parser that is built in to many browsers these days. If it's not available, you can use the JSON2 library , which provides the same interface, as a fallback.

var json = JSON.parse(response);
var userid = json.user_id;

Answer 2

尝试不带eval(response)然后执行以下操作：

var userid = response.user_id;

Answer 3

I think you want to do

var json = JSON.parse(response);
var userid = json.user_id;
