一个简单的jsonp例子

现在jsonp很流行看见很多人都写得很复杂，现在给一个简单的调用

首先写一个服务端，创建TestHandler.ashx

[csharp]
public void ProcessRequest(HttpContext context) 
      { 
          context.Response.ContentType = "application/x-javascript"; 
          string callback = context.Request.QueryString["callback"].Trim(); 
          string name = context.Request.QueryString["name"].Trim(); 
          string str = callback + "([{\"SuitName\":\"" + name + "\"}]);"; 
          context.Response.Write(str); 
      } 
htm的代码：

[html]
<div> 
       <input type="button" id="btn1" value="Test Handler" /> 
       <div id="msg" style="background-color: Red; width: 100px; height: 50px"> 
       </div> 
       <script type="text/javascript"> 
           function displayResult(data) { 
               $("#msg").text(data[0].SuitName); 
           } 
           $(function () { 
 
               $("#btn1").click(function () { 
                   var url = "TestHandler.ashx?name=majiang&callback=displayResult" 
                   url = "http://starajax.vancl.com/GetSuitsWithLikesBySuitIds?suitIds=9396493&callback=displayResult" 
                   $.getScript(url); 
 
               }); 
 
           }); 
       </script> 
   </div> 

呵呵 这样及可以了 够简单吧
