jquery ajax jsonp跨域调用实例代码_jquery

客户端代码

复制代码 代码如下:

   


   

   

   

   

   

       

服务器端代码

复制代码 代码如下:

 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();
        }
    }

客户端页面和服务器端页面在两个项目中，以便进行跨域调用测试。

跨域实例代码（需要加载jquery，页面为utf-8编码）：

复制代码 代码如下:

 
  

';
    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();
       
     

jsonp代码：

复制代码 代码如下:
