asp.net+jquery Jsonp使用方法

代码如下：

string callback = Request["callback"]; 
string response = string.Format("\"value1\":\"{0}\",\"value2\":\"{1}\", v1, v2); 
string call = callback + "({" + response + "})"; 
Response.Write(call);

代码如下：

var url = "xxx.aspx?p1=1&p2=2&callback=?"; 
jQuery.getJSON(url, function(data) { 
alert("value1：" + data.value1+ " value2：" + data.value2); 
});

代码如下：

jQuery.ajax({ 
type:"get", 
url: "xxx.aspx", 
dataType : "jsonp", 
jsonp: "callback", 
data: "p1=1&p2=2&callback=?", 
success:function(msg){ 
alert("value1：" + data.value1+ " value2：" + data.value2); 
} 
});
