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
