第六章?網(wǎng)站前臺(tái)之用戶注冊(cè)和登陸?

1、首先新建用戶注冊(cè)頁(yè)面Register.aspx ，添加注冊(cè)時(shí)需要的相應(yīng)控件，在注冊(cè)代碼中使用了四種類(lèi)型的驗(yàn)證，具體如下:?

（1）、判空驗(yàn)證?

*用戶名：

ControlToValidate ="txtName">

（2）、比較驗(yàn)證?

*確認(rèn)密碼

ControlToValidate ="txtRePwd">

（3）、范圍驗(yàn)證?

*年齡

runat ="server" Width ="27px">

歲

ErrorMessage ="輸入1-120之間的數(shù)字" Type ="Integer"

ControlToValidate ="txtAge"

MaximumValue ="120" MinimumValue ="1">

ControlToValidate ="txtAge">

（4）、正則表達(dá)式驗(yàn)證?

*郵箱

ControlToValidate ="txtEmail">

ValidationExpression

運(yùn)行效果如下:?

?

2、在填寫(xiě)出生日期的時(shí)候，最好是提供選擇，首先需要引用一個(gè)Calendar 的js 文件，然后在文本框中添加onclick 的事件調(diào)用腳本，具體代碼如下：? ");

//成功后提示再跳轉(zhuǎn)

}

else

{

BLL. Users userBll = new BLL.Users ();

Model. Users userModel = new Model.Users ();

userModel.userBirthday =Convert .ToDateTime( txtBirthday.Text.Trim());

userModel.userImg = "" ;

userModel.userName = txtName.Text.Trim();

userModel.userPassword = txtPwd.Text.ToString().Trim();

userModel.userEmail = txtEmail.Text.Trim();

userModel.userRegisterTime = DateTime .Now;

userModel.userSex = Convert .ToInt32(radio.SelectedItem.Value) == 0 ? false : true ; userModel.userState = "0" ;

userModel.userTel = txtPhone.Text.Trim();

userModel.userLastLoginTime = DateTime .Now;

if (userBll.Add(userModel) > 0)

{

ClientScript.RegisterStartupScript(this .GetType(), "success" , "");

//成功后提示再跳轉(zhuǎn)

}

}

}

運(yùn)行效果如下：

6、注冊(cè)功能完成后，如果需要進(jìn)行一些其他特殊操作，會(huì)員需要登陸到系統(tǒng)，接下來(lái)演示登陸功能的實(shí)現(xiàn)，首先新建Login.aspx 的頁(yè)面，進(jìn)行頁(yè)面布局，具體代碼如下：?

運(yùn)行效果圖如下：

?

7、前臺(tái)代碼寫(xiě)完之后，開(kāi)始編寫(xiě)登陸事件的后臺(tái)代碼, 具體代碼如下：?protected void Button1_Click(object sender, EventArgs e)

{

BLL. Users userBll = new BLL.Users ();

string userName = txtName.Text.Trim();

string userPwd = txtPwd.Text.Trim();

DataSet ds=new DataSet ();

ds = userBll.GetList(" userName='" userName "' and userPwd='" userPwd "'" ); if (ds != null )

{

if (ds.Tables[0].Rows.Count > 0)

{

ClientScript.RegisterStartupScript(this .GetType(), "success" , "");

//成功后提示再跳轉(zhuǎn)

}

else

{

ClientScript.RegisterStartupScript(this .GetType(), "success" , "");

//成功后提示再跳轉(zhuǎn)

}

}

else

{

ClientScript.RegisterStartupScript(this .GetType(), "success" , "");

//成功后提示再跳轉(zhuǎn)

}

}

運(yùn)行效果圖如下：?

?

8、登陸成功后，跳轉(zhuǎn)進(jìn)入個(gè)人空間，可以進(jìn)行個(gè)人頭像的修改，具體代碼如下：?Model. Users userModel = new Model.Users ();

BLL. Users userBll = new BLL.Users ();

protected void Page_Load(object sender, EventArgs e)

{

if (!IsPostBack)

{

if (Session["userModel" ] != null )

{

userModel = (Model.Users )Session["userModel" ];

if (userModel.userImg == "" ||userModel.userImg ==null )

{

Image1.ImageUrl = "../Images/admin/avatar.png";

}

else

{

Image1.ImageUrl = "../Images/admin/" userModel.userImg;

}

lblName.Text = userModel.userName;

lblPhone.Text = userModel.userTel.Trim();

lblSex.Text = userModel.userSex == false ? " 女" : " 男" ;

}

else

{

ClientScript.RegisterStartupScript(this .GetType(), "success" , "");

//成功后提示再跳轉(zhuǎn)

}

}

}

protected void Button1_Click(object sender, EventArgs e)

{

userModel = (Model.Users )Session["userModel" ];

if (FileUpload1.HasFile == false )

{

ClientScript.RegisterStartupScript(this .GetType(), "success" , "");

return ;

}

string IsXls = System.IO.Path .GetExtension(FileUpload1.FileName).ToString().ToLower(); if (IsXls != ".jpg" )

{

ClientScript.RegisterStartupScript(this .GetType(), "success" , "");

return ;

}

string str = (DateTime .Now).ToString("yyyyMMddHHmmss" );

string FileName = str IsXls;

try

{

string savePath;

savePath = Server.MapPath("../Images/admin/" FileName);

FileUpload1.SaveAs(savePath);

//UsersModel.userId = int.Parse(Session["userId"].ToString());

userModel.userImg = FileName;

//usersBLL.Add(UsersModel);

bool bl= userBll.Update(userModel);
