在子页中隐藏模板页中的div示例代码

<!--登录小div--> 
<div class="loginDiv"> 
<div class="LoginDivTitle"> 
会员登录 
</div> 
<table class="loginTable"> 
<tr> 
<td class="LoginLabel">用户名:</td> 
<td><input type="text" class="loginTxt" id="txtUserName" /></td> 
</tr> 
<tr> 
<td class="LoginLabel">密码:</td> 
<td><input type="password" class="loginTxt" id="txtPass" /></td> 
</tr> 
<tr> 
<td class="LoginTdButtons" colspan="2"> 
<input src="../images/az-login-gold-3d.gif" type="image" id="btnLogin" /> 
<input src="../images/az-newuser-gold-3d.gif" type="image" id="btnReg" /> 
</td> 
</tr> 
</table> 
</div> 
<div class="loginOkDiv" style="display:none"> 
<span class="spanLoginOk" id="spanUserInfo"> 
尊敬的<%=serverUserName %>,欢迎你光临! 
</span> 
</div> 
 
<1>.在后台Main.master中的代码 
 代码如下:

protected string serverUserName; 
protected void Page_Load(object sender, EventArgs e) 
{ 
if (!IsPostBack) 
{ 
Model.Users user = Session["currUser"] as Model.Users; 
if (user != null) 
{ 
serverUserName = user.Name; 
} 
} 
} 
 
<2>MainPage主页面中后台代码，它是继承于模板页Main.master的 
 代码如下:

public partial class MainPage : System.Web.UI.Page 
{ 
protected void Page_Load(object sender, EventArgs e) 
{ 
if (!IsPostBack) 
{ 
Model.Users user = Session["currUser"] as Model.Users; 
if (user != null) 
{ 
common.CommonCode.ExecuteScriptFunc(this,true); 
} 
else 
{ 
common.CommonCode.ExecuteScriptFunc(this,false); 
} 
} 
} 
} 
 
<3>ExecuteScriptFunc封装代码 
 代码如下:

public static void ExecuteScriptFunc(System.Web.UI.Page page, bool bShowUserInfo) 
{ 
string func = "function showUser(isLogin){\r\n\r\nif (isLogin) {\r\n" + 
"$(\".loginDiv\").hide();\r\n" + 
"$(\".loginOkDiv\").show();\r\n" + 
"}\r\n" + 
"else {\r\n" + 
"$(\".loginDiv\").show();\r\n" + 
"$(\".loginOkDiv\").hide();\r\n" + 
"}}"; 
string func1 = ""; 
if (bShowUserInfo) 
{ 
func1 = func + "\r\n" + 
"$(function(){\r\nshowUser(true)" + 
"});"; 
} 
else 
{ 
func1 = func + "\r\n" + 
"$(function(){\r\nshowUser(false)" + 
"});"; 
} 
page.ClientScript.RegisterStartupScript(page.GetType(), Guid.NewGuid().ToString(), 
func1, true); 
//page.ClientScript.RegisterStartupScript(page.GetType(), Guid.NewGuid().ToString(), 
// func1); 
}
