本文實例講述了jquery+ajax實現跨域請求的方法。分享給大家供大家參考。具體實現方法如下：
說明：這里的dataType 為 "jsonp" ；type 只能為 GET
前臺請求代碼如下：
復制代碼代碼如下:
$.ajax({
type: "GET",
url: "http://www.xxx.com/Rest/ValidAccountsExists.aspx?accounts=admin",
dataType: "jsonp",
jsonp: "jsoncallback",
success: function (result) {
alert(result.Success);
alert(result.Content);
},
type: "GET",
url: "http://www.xxx.com/Rest/ValidAccountsExists.aspx?accounts=admin",
dataType: "jsonp",
jsonp: "jsoncallback",
success: function (result) {
alert(result.Success);
alert(result.Content);
},
error: function (result, status) {
//處理錯誤
}
});
后臺處理代碼 ValidAccountsExists.aspx如下：
復制代碼代碼如下:
string accounts = GameRequest.GetQueryString("accounts");
string jsoncallback = GameRequest.GetQueryString("jsoncallback");
Response.ContentEncoding =System.Text.Encoding.UTF8;
Response.ContentType = "application/json";
Response.Write(jsoncallback + "({/"Success/":/"True/",/"Content/":/"" + accounts + "/"})");
Response.End();
string jsoncallback = GameRequest.GetQueryString("jsoncallback");
Response.ContentEncoding =System.Text.Encoding.UTF8;
Response.ContentType = "application/json";
Response.Write(jsoncallback + "({/"Success/":/"True/",/"Content/":/"" + accounts + "/"})");
Response.End();
希望本文所述對大家的jQuery程序設計有所幫助。
