页面前面：
<div id="login" runat="server"> <span class="log_title">账号（昵称）：</span><input class="log_input" runat="server" id="t_LogName" name="t_LogName" type="text" placeholder="请输入账号（昵称）" /> <span class="log_title">密码：</span><input class="log_input" runat="server" id="t_LogPass" name="t_LogPass" type="password" placeholder="请输入密码" /> <asp:Button ID="Button1" runat="server" Text="登陆" OnClick="Button1_Click" CssClass="button" EnableTheming="False" /> <asp:Button ID="Button2" runat="server" CssClass="button" Text="注册" PostBackUrl="~/regist.aspx"></asp:Button> </div> <div id="logstate" runat="server" visible="false">欢迎您：<span><asp:Literal ID="uesrName" runat="server"></asp:Literal></span><a runat="server" onserverclick="out_click">退出</a></div>
要引入的样式：
#login { top:0; left: 0; width:580px;height:25px;background:pink;position: relative;float:left}
.button { height: 25px;font-size: 14px; background-color: #0998ff; color: #FFF;padding:3px 12px 5px 12px;border: 0px; vertical-align: middle;margin-left:5px;float:left; }
.button:hover{ background-color: #6699FF;color:#000;cursor:pointer }
.log_input{background-color:#FFF; border:1px solid #d5cfc2;width:130px;height:23px; font-size:14px;vertical-align:middle;float:left}
.log_title{width:90px; display:inline-block; text-align:right;line-height:25px; float:left;color:#FFF;}
#Head_logstate {/*width:200px;*/height:25px;color:#FFF;font-size:14px;line-height: 25px;/*background:blue;*/float:left;position: relative;}
#Head_logstate span { color:#f00;font-weight:800;margin-right:20px}
#Head_logstate a {height:25px;font-size: 14px; background-color: #0998ff; color: #FFF;padding:0 12px 0 12px;border: 0px; vertical-align: middle;float:right}
#Head_logstate a:hover{ background-color: #6699FF;color:#000;cursor:pointer }
说明一下，应该是我把这个放在控件Head里，所以引入页面的时候，
logstate这个样式找不到，后来，我就改是#Head_logstate，才显示正常，而在控件里div的样式还是用的<div id="logstate" runat="server" visible="false">....
控件的cs核心代码：
protected string mynames; protected string myID; protected void Page_Load(object sender, EventArgs e) { if (!IsPostBack) { HttpCookie cookie = Request.Cookies["nickname"]; if (cookie != null) { mynames = cookie.Value; GetLogin(); } } }
protected void Button1_Click(object sender, EventArgs e) { string name = t_LogName.Value.Trim(); string pw = t_LogPass.Value.Trim(); if (name.IndexOf("‘") > 0 || name.IndexOf("--") > 0) { HelperJS.Show(this.Page, "账号（昵称）存在非法字符!"); return; } if (name != string.Empty && pw != string.Empty) { //检查用户名密码 DataTable dt = HelperExecuteSql.Query("select ID,nickname,pw from _user where nickname=‘" + name + "‘ and pw =‘" + pw + "‘").Tables[0]; if (dt.Rows.Count > 0) { myID = dt.Rows[0]["ID"].ToString(); //Session["nickname"] = name; //Session["ID"] = Convert.ToInt32(dt.Rows[0][0].ToString()); //uesrName.Text = dt.Rows[0]["nickname"].ToString(); if (Request["ReturnUrl"] == null || Request["ReturnUrl"] == "") { string nowtime = DateTime.Now.ToString(); //获取当前时间 HttpCookie cookie = new HttpCookie("nickname", HttpUtility.UrlEncode(name));//获取用户的用户名 cookie.Expires = DateTime.Now.AddHours(2);//设置cookie过期时间为2小时后 Response.Cookies.Add(cookie);//将cookie写入客户端 HttpCookie cookie1 = new HttpCookie("nowTime", nowtime); cookie1.Expires = DateTime.Now.AddHours(2);//设置cookie过期时间为2小时后 Response.Cookies.Add(cookie1);//将cookie1写入客户端 HttpCookie cookie2 = new HttpCookie("ID", myID);//获取用户的ID Response.Cookies.Add(cookie2);//将cookie2写入客户端 Response.Write(" <script language=javascript>window.location.href=document.URL;</script>"); //刷新 } else { Server.Transfer(Request["ReturnUrl"]); } } else { HelperJS.Show(this.Page, "用户名或密码不正确!"); } } else { HelperJS.Show(this.Page, "用户名或密码不能为空!"); } } protected void out_click(object sender, EventArgs e) //退出 { Response.Cookies["nickname"].Expires = DateTime.Now;//cookie将马上过期 login.Visible = true; logstate.Visible = false; Response.Write(" <script language=javascript>window.location.href=document.URL;</script>"); //刷新 }
