程序小海 2012-12-10 09:20:41

大家好我想练习个简单的 ajax的登录但是老是打不到我想要的结果

但是朋友的电脑上可以显示我不知道具体是什么原因造成的希望大家指点下！谢谢！

Default.aspx中：js

    <script type="text/javascript">

        var xmlhttp;

        var result; 

        function btn_logn_Clock() {

            var userName = document.getElementById("username").value;

            var userPwd = document.getElementById("password").value;

            xmlhttp = window.XMLHttpRequest ? new XMLHttpRequest() : new ActiveXObject("Microsoft.XMLHTTP"); 

            var data = "username=" + encodeURIComponent(userName)

                         + "&password=" + encodeURIComponent(userPwd);

            xmlhttp.open("Post", "Default2.aspx", true);

            xmlhttp.setRequestHeader("Content-Type", "application/x-www-form-urlencoded");

            xmlhttp.onreadystatechange = function () {

                if (xmlhttp.readyState == 4 && xmlhttp.status == 200) {

                    result = xmlhttp.responseText;

                }

            }

            xmlhttp.send(data); 

        }

    </script>

Default2.aspx.cs中

 protected void Page_Load(object sender, EventArgs e)

    {

        string userName = string.Empty;

        string password = string.Empty;

        userName = Request.Form["username"];

        password = Request.Form["password"];

        Response.Write("姓名：’" + userName + "'<br/>  密码：" + password);

        Response.End();

    }

谢谢大家！
