Jsonp的用法非常简单，不过需要服务器端和客户端同时支持。
服务器端
string
callback
=
Request[
"
callback
"
];
string response = string .Format( " / " value1/ " :/ " { 0 }/ " ,/ "value2 / " :/ " { 1 }/ " ,v1,v2);
string call = callback + " ({ " + response + " }) " ;
Response.Write(call);
string response = string .Format( " / " value1/ " :/ " { 0 }/ " ,/ "value2 / " :/ " { 1 }/ " ,v1,v2);
string call = callback + " ({ " + response + " }) " ;
Response.Write(call);
客户端
1、使用getJson
var
url
=
"
xxx.aspx?p1=1&p2=2&callback=?
"
;
jQuery.getJSON(url, function (data){
alert( " value1： " + data.value1 + " value2： " + data.value2);
});
jQuery.getJSON(url, function (data){
alert( " value1： " + data.value1 + " value2： " + data.value2);
});
2、使用ajax
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);}});
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);}});
