json和Jsonp 使用总结（2）

1.Jsonp的使用

var phoneAgent = navigator.userAgent; var urlDomaintest = " ";

function getHref() {  var href = window.location.href;  return href; } var PhoneAgent=“”；

$(function () {  

       $.ajax

      ({  

           async: false,  

         url: urlDomaintest + "Home/CloudUserInfo",  

          type: 'GET',   

          data: { UserName: phoneAgent, UserEmail: getHref() },   

          dataType: "jsonp",   jsonp: "callback",   

          success: function (data) {   

           console.log("success");    

           if (data.Status==1)     {         var docSpan = document.getElementById("NumSpan");         docSpan.innerHTML = data.ResultNum;     }    

          else     {         var docSpan = document.getElementById("NumSpan");         docSpan.innerHTML = "3500";     }   

           }  

           }) });

           //对应接口

          public ActionResult CloudUserInfo(string callback, string UserName, string UserEmail)      

          {            

                 AjaxResult<string> jsonResult = new AjaxResult<string> { Status = -1, ResultNum = 0, Data = "" };           

                  //return Json(jsonResult, JsonRequestBehavior.AllowGet);            

                 return JavaScript(string.Format("{0}({1});", callback, Newtonsoft.Json.JsonConvert.SerializeObject(jsonResult)));        

            }

3. jonp  处理

$.ajax({
    async: false,
    url: url + "/Collect/StInfoData",
    type: 'GET',
    data: { 'userData': JSON.stringify(data) },
    dataType: "jsonp",
    jsonp: "jsonpcallback",
    success: function (data)
    {
        alert("324345");
        console.log(data);
        var st = eval(data);
      
        if (data.Status > 0) {
            alert("提交成功");
        }
        else { alert("提交失败"); }
    }
})

  public ActionResult StInfoData(string userData,string jsonpcallback)
        {
            AjaxResult jsonResult = new AjaxResult { Status = -1, Message = "保存信息出错" };

  return JavaScript(string.Format("{0}({1});", jsonpcallback, Newtonsoft.Json.JsonConvert.SerializeObject(jsonResult)));

}

3.代码处理

jsonp  无法异步大量数据
