jQuery 学习笔记四 Ajax提交数据

<p>1.采用$.post提交数据</p>
<p>新建页面Reg.htm与reg.aspx，其中html用作采集数据的UI，aspx页面用来提供ajax后台调用方法</p>
<p></p>
<p>html代码</p>
<p><textarea cols="86" rows="11" name="code" class="javascript"> &lt;mce:script src="Scripts/jquery-1.4.1.js" mce_src="Scripts/jquery-1.4.1.js" type="text/javascript"&gt;&lt;/mce:script&gt;
    &lt;mce:script language="javascript" type="text/javascript"&gt;&lt;!--
        function Submit1_onclick() {
            $.post("reg.aspx", { ajax: "a", userName: $("#txtName").val(), pwd: $("#txtPwd").val(),
            qq:$("#txtQQ").val(),email:$("#txtEmail").val(),phone:$("#txtPhone").val(),mobile:$("#txtMobile").val() }, function (msg) { });
        }
// --&gt;&lt;/mce:script&gt;</textarea></p>
<p>aspx后台代码</p>
<p><textarea cols="86" rows="15" name="code" class="c-sharp"> protected void Page_Load(object sender, EventArgs e)
        {
            if (Request.Form["ajax"]!=null)
            {
                RegUser(Request.Form["userName"], Request.Form["pwd"]
                    , Request.Form["qq"], Request.Form["email"], Request.Form["phone"], Request.Form["mobile"]);
            }
        }
        private string RegUser(string userName,string pwd,string qq,string email,string phone,string mobile)
        {
            try
            {
                DataClasses1DataContext _DataClasses1DataContext = new DataClasses1DataContext();
                UserInfo userInfo = new UserInfo();
                userInfo.UserName = userName;
                userInfo.Password = pwd;
                userInfo.QQ = qq;
                userInfo.Email = email;
                userInfo.Phone = phone;
                userInfo.Mobile = mobile;
             var user=   _DataClasses1DataContext.UserInfo.Where(m=&gt;m.UserName==userName).FirstOrDefault();
             if (user != null)
             {
                 return "1|用户名已存在";
             }
             else {
                 _DataClasses1DataContext.UserInfo.InsertOnSubmit(userInfo);
                 _DataClasses1DataContext.SubmitChanges();
                 return "0|注册成功";
             }
             
              
            }
            catch (Exception ex)
            {
                return "-1|"+ex.ToString();
            }
          

        }
