Question

js代码

function cha(){
alert(0);
var zhi = $('#bu').val();
alert(1);
$.ajax({
type: "get",

            url: "http://192.168.1.12:8080/zfba/app/json.json",

            dataType: "jsonp",
            jsonp: "jsonp", //传递给请求处理程序或页面的，实现跨域。
            jsonpCallback: "callback", ////服务端用于接收callback调用的function名的参数
            contentType: "application/json; charset=utf-8",
            success: function (data) {
                 alert('成');
                // alert(json.msg);
                // alert(JSON.stringify(data)); 
            },
            error: function () {
                debugger;
                alert('败');
            }
        });

json.json内容

{
"success": true,
"content": [
{
"id": "bf152335d24f4a3db47103eca2046302",

用jsonp跨域请求的话,服务器端返回 json格式是callback({...});
