将JSON对象添加到DIV

Question

我有一个JSON对象,我作为对AJAX调用的响应:

{ "Score": 5, "OS": "Windows 7" }

我想将它添加到div但是以下不起作用,data.OS或者data.Score只是返回undefined

$.ajax({
     type: "POST",
     url: '/details',
     data: JSON.stringify(IP), 
     contentType: 'application/json;charset=UTF-8',   
     success: function(data) {

        $('#OSdetails').append('<div id="details">Operating System: ' + data.OS + '</div>');

     }
}); 

我究竟做错了什么？

Answer 1

$.ajax({
     dataType: 'JSON',         <==== THIS IS MISSING
     type: "POST",
     url: '/details',
     data: JSON.stringify(IP), 
     contentType: 'application/json;charset=UTF-8',   
     success: function(data) {

dataType 指定预期的数据类型并允许自动转换
