 今天研究了AJAX使用JSONP進行跨域調用的方法,發現使用GET方式和POST方式都可以進行跨域調用,這裡簡單分享下,方便需要的朋友

用戶端代碼  代碼如下:<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="WebForm1.aspx.cs" Inherits="WebApp.WebForm1" %><!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"><html xmlns="http://www.w3.org/1999/xhtml" ><head runat="server"><script src="jquery-1.7.1.min.js" type="text/javascript"></script><script type="text/javascript">    function aa() {        $.ajax({            url: "http://localhost:12079/WebForm2.aspx",            data: "p1=1&p2=2&callback=?",            type: "post",            processData: false,            timeout: 15000,            dataType: "jsonp",  // not "json" we'll parse            jsonp: "jsonpcallback",            success: function(result) {            alert(result.value1);            }        });    } </script>    <title></title></head><body>    <form id="form1" runat="server">    <div>     </div>    </form>    <p>        <input id="Button1" type="button" value="button" onclick="aa()" /></p></body></html>  伺服器端代碼  代碼如下: public partial class WebForm2 : System.Web.UI.Page    {        protected void Page_Load(object sender, EventArgs e)        {                     string callback = Request["callback"];             string v1="1";            string v2="2";            string response = "{"value1":"" + v1 + "","value2":"" + v2 + ""}";            string call = callback + "(" + response + ")";            Response.Write(call);            Response.End();        }    }  用戶端頁面和伺服器端頁面在兩個項目中,以便進行跨域調用測試。 跨域執行個體代碼(需要載入jquery,頁面為utf-8編碼):  代碼如下: <!--拉勾招聘資料-->  <script type="text/javascript">   function success_jsonpCallback(data){    var html = '';    var pos = '';    html += '<ul>';    jQuery.each(data, function(k, v) {                 if(k<10){                  pos = '【' + v.city+ '】' + v.positionName + '('+ v.salary +') - '+v.companyName;      if(pos.length > 20){       pos = pos.substring(0,19)+'...';                     }                     html += '<li><a href="'+v.posiitonDetailUrl+'" target="_blank" title="【' + v.city+ '】' + v.positionName + '('+ v.salary +') - '+v.companyName+'">'+pos+'</a></li>';                 }    });    html += '</ul><div class="more-link"><a href="http://www.lagou.com/jobs/list_%E5%89%8D%E7%AB%AF%E5%BC%80%E5%8F%91" target="_blank">更多</a></div>';    jQuery('#lagouData').html(html);   }    function getLagouData() {    jQuery.ajax({     async:false,     url: "http://www.lagou.com/join/listW3cplus?kd=%E5%89%8D%E7%AB%AF%E5%BC%80%E5%8F%91",     type: "GET",     dataType: "jsonp",     jsonpCallback: 'success_jsonpCallback',     contentType: "application/jsonp; charset=utf-8",     success: function(data) {      success_jsonpCallback(data);     }    });   }   getLagouData();        </script>      <div id="lagouData"></div>  jsonp代碼:  複製代碼 代碼如下:success_jsonpCallback([{"city":"廣州","companyName":"POCO.CN","createTime":"15:02發布","posiitonDetailUrl":"http://www.lagou.com:80/jobs/16868.html","positionAdvantage":"身處凝聚力團隊,老城區上班交通便利,雙休","positionName":"商業前端開發工程師","salary":"4k-7k"},{"city":"北京","companyName":"美通雲動(北京)科技有限公司","createTime":"14:47發布","posiitonDetailUrl":"http://www.lagou.com:80/jobs/16866.html","positionAdvantage":"Html5技術最棒的團隊","positionName":"Web前端開發","salary":"4k-8k"},{"city":"杭州","companyName":"口袋購物","createTime":"14:42發布","posiitonDetailUrl":"http://www.lagou.com:80/jobs/13024.html","positionAdvantage":"廣闊的發展平台、自我價值體現的地方","positionName":"web前端開發工程師","salary":"8k-12k"},{"city":"北京","companyName":"布丁移動","createTime":"14:02發布","posiitonDetailUrl":"http://www.lagou.com:80/jobs/1498.html","positionAdvantage":"三餐、周圍美女如雲","positionName":"Android開發工程師","salary":"10k-20k"},{"city":"北京","companyName":"布丁移動","createTime":"14:02發布","posiitonDetailUrl":"http://www.lagou.com:80/jobs/2539.html","positionAdvantage":"三餐,小橋流水人家,美女","positionName":"ios開發工程師","salary":"10k-20k"},{"city":"上海","companyName":"天天動聽","createTime":"00:55發布","posiitonDetailUrl":"http://www.lagou.com:80/jobs/11494.html","positionAdvantage":"創業氛圍 講求小而美","positionName":"Android開發工程師","salary":"8k-16k"},{"city":"北京","companyName":"LBE安全大師","createTime":"11:39發布","posiitonDetailUrl":"http://www.lagou.com:80/jobs/5983.html","positionAdvantage":"五險一金 績效獎金","positionName":"Android開發工程師","salary":"8k以上"},{"city":"北京","companyName":"點心移動","createTime":"11:24發布","posiitonDetailUrl":"http://www.lagou.com:80/jobs/16736.html","positionAdvantage":"技術導向的團隊氛圍,全方位的福利待遇","positionName":"Android","salary":"15k-25k"},{"city":"廣州","companyName":"荔枝FM","createTime":"10:44發布","posiitonDetailUrl":"http://www.lagou.com:80/jobs/16634.html","positionAdvantage":"連堅持跑步、保持體重都有獎勵哦!","positionName":"WP手機開發工程師","salary":"16k-25k"},{"city":"北京","companyName":"網銀-京東子公司","createTime":"10:08發布","posiitonDetailUrl":"http://www.lagou.com:80/jobs/14162.html","positionAdvantage":"負責京東商城-互連網金融產品 JS開發","positionName":"Javascript 前端開發工程師","salary":"10k-20k"}])
