JQuery運用ajax注冊用戶實例(后臺asp.net)

更新時間：2009年12月21日 23:21:32 作者：

JQuery運用ajax注冊用戶實例，其實那中后臺語言都是差不多的形式。

 
//JS代碼 

function checkname() { 
var Msg = document.getElementById("d_username"); 
var chk = CheckN(); 
if (chk) { 
$.ajax({ url: 'registerOK.aspx', 
type: 'POST', 
data: { lb: "checkname", username: $("#username").val() }, 
dataType: 'html', 
timeout: 1000, 
error: function() { alert('出現未知錯誤，請與QQ:6434789聯系。'); }, 
success: function(data) { 
if (data == "對不起，該用戶名已被注冊！") { 
Msg.className = "d_err"; 
Msg.innerHTML = data; 
$("#hiddencheckname").val("no"); 
} 
if (data == "恭喜，該用戶名可以注冊！") { 
Msg.className = "d_ok"; 
Msg.innerHTML = data; 
$("#hiddencheckname").val("yes"); 
} 
if (data == "該用戶名不能為中文！") { 
Msg.className = "d_err"; 
Msg.innerHTML = data; 
$("#hiddencheckname").val("no"); 
} 
if (data == "請輸入用戶名！") { 
Msg.className = "d_err"; 
Msg.innerHTML = data; 
$("#hiddencheckname").val("no"); 
} 
} 
}); 
} 
} 

function CheckN() { 
var Msg = document.getElementById("d_username"); 
var chk = true; 
if (checkIsChinese(document.getElementById("username").value)) { 
Msg.className = "d_err"; 
Msg.innerHTML = "用戶名不能為中文！"; 
chk = false; 
} 
if (document.getElementById("username").value.length < 4) { 
Msg.className = "d_err"; 
Msg.innerHTML = "用戶名不能少于4個字符！"; 
chk = false; 
} 
return chk; 
} 

function chk_reguser() { 
var chk = true 
// if (!checkname()) { chk = false; } //jquery進行變量賦值不能與js里面的變量共用，故success: function(data) {}里面定義的任何變量與所在的js代碼中的變量是不相通的，所以我就找一個種比較偏（非正式）的方法，為在html中加入隱藏的Input并在js里面設置$("#hiddencheckname").val("no"); 
if (!CheckN()) {chk = false;} 
if ($("#hiddencheckname").val() == "no") { chk = false; }//這個是對其判斷 
if (!checkpwd()) { chk = false; }//這些跟CheckN()差不多一樣，只是對表單里面的元素進行驗證 
if (!checkpwd1()) { chk = false; } 
if (!checkquestion()) { chk = false; } 
if (!checkanswer()) { chk = false; } 
if (!checkxq()) { chk = false; } 
if (!checkrealname()) { chk = false; } 
if (!checktel()) { chk = false; } 
if (!checkQQMSN()) { chk = false; } 
if (!checkEmail()) { chk = false; } 
if (!checkaddress()) { chk = false; } 
if (chk) { 
$.ajax({ url: 'registerOK.aspx', 
type: 'POST', 
data: { lb: "reguser", username: $("#username").val(), password: $("#pwd").val(), question: $("#question").val(), answer: $("#answer").val(), xqcode: $("#ctl00_CPH_Main_DDL_xq").val(), realname: $("#realname").val(), sex: $("input[@name=sex][@checked]").val(), tel: $("#tel").val(), QQMSN: $("#QQMSN").val(), email: $("#email").val(), address: $("#address").val() }, 
dataType: 'html', 
timeout: 1000, 
error: function() { alert('出現未知錯誤，請與QQ:6434789聯系。'); }, 
success: function(data) { 
if (data == "success") { 
alert("注冊成功！"); 
window.location.href = "/member/index.aspx"; 
} 
else { 
alert("注冊失敗，原因可能為用戶名已被注冊！"); 
} 
} 
}); 
return (true); 
} 
return (false); 
} 

//HTML頁

只要做類似于這樣的表單

復制代碼代碼如下:

 
<input id="username" type="text" onBlur="checkname()" /> 
<div class=d_default id=d_username>請輸入4位以上的英文字符或數字！</div> 
<input id="Button_OK" type="button" onclick="return chk_reguser();"/> 

//registerOK.aspx.cs

復制代碼代碼如下:

 
using System; 
using System.Collections.Generic; 
using System.Linq; 
using System.Web; 
using System.Web.UI; 
using System.Web.UI.WebControls; 
using BLL; 

public partial class registerOK : System.Web.UI.Page 
{ 
user user = new user(); 
protected void Page_Load(object sender, EventArgs e) 
{ 
if (!IsPostBack) 
{ 
string lb = Request["lb"]; 
string username = Request["username"]; 
string password = Request["password"]; 
string question = Request["question"]; 
string answer = Request["answer"]; 
string xqcode = Request["xqcode"]; 
string realname = Request["realname"]; 
string sex = Request["sex"]; 
string tel = Request["tel"]; 
string QQMSN = Request["QQMSN"]; 
string email = Request["email"]; 
string address = Request["address"]; 
if (lb == "checkname") 
{ 
Response.Write(user.CheckUserName(username)); 
} 
if (lb == "reguser") 
{ 
string name = user.CheckUserName(username); 
if (name == "恭喜，該用戶名可以注冊！") 
{ 
user.Add(username, password, question, answer, xqcode, realname, sex, tel, QQMSN, email, address); 
Response.Write("success"); 
} 
else 
{ 
Response.Write("fail"); 
} 
} 
} 
} 
}
