还有就是，之前遇到返回xml的，也是说那个 < 和 > 有问题。我就没用xml了。想问问，用过ajax请求数据，返回xml是怎么解析的。我这边报错，现在json也报错了。

具体可以参考这个帖子：https://bbs.csdn.net/topics/392384293

你这个返回的数据是json的 浏览器会按js语法解析他的， 所以会报 语法错误，一个方法 ajax 请求时 的dataType 属性改为jsonp 或者 text 就不会报错了， 不过这样做 有可能报跨域错误，主要看你 服务器 支不支持跨域访问了

我就是用的jsonp; 格式如下： $.ajax({ type:"get", //请求方式 async:true, //是否异步 url:"http://v.juhe.cn/toutiao/index?type=top&key=11111111111", dataType:"jsonp", //跨域json请求一定是jsonp jsonp: "type", //跨域请求的参数名，默认是callback //jsonpCallback:"successCallback", //自定义跨域参数值，回调函数名也是一样，默认为jQuery自动生成的字符串 success: function(data) { //请求成功处理，和本地回调完全一样 var json = eval('('+data+')'); console.log(json.url); }, error: function() { //请求出错处理 } }); 这个格式对不对啊

jsonp要求后端服务器支持的，你的属性里面 //jsonpCallback:"successCallback", 后端返回数据的时候要加上 类似这种 response.callback("successCallback")这种， 然后你前端写个 function successCallback(data){ alert(data) } 才可以，要不然只前端是解决不了这个问题的
