Response.Redirect 打开新窗口的两种方法
一般情况下,Response.Redirect 方法是在服务器端进行转向,因此,除非使用 Response.Write("<script>window.location='http://dotnet.aspx.cc';</script>") 方法外,是不能在新窗口打开所指定的 URL 地址的。但是,如果仔细分析一下,如果设置 form 元素的 target 属性,还是有办法打开新窗口的。下面就是可以采用的两种方法。
方法一:在服务器端设置 target 属性,这个方法也非常适用于客户端不支持脚本的情况。代码如下:
<%@ Page Language="C#" AutoEventWireup="true" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<script runat="server">
protected void Page_Load(object sender, EventArgs e)
{
form1.Target = "_blank";
}
protected void Button1_Click(object sender, EventArgs e)
{
Response.Redirect("http://dotnet.aspx.cc");
}
</script>
<html xmlns="http://www.w3.org/1999/xhtml">
<head id="Head1" runat="server">
<title></title>
</head>
<body id="b" runat="server">
<form id="form1" runat="server">
<asp:Button ID="Button1" runat="server" OnClick="Button1_Click" Text="打开新窗口或者新 Tab " />
</form>
</body>
</html>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<script runat="server">
protected void Page_Load(object sender, EventArgs e)
{
form1.Target = "_blank";
}
protected void Button1_Click(object sender, EventArgs e)
{
Response.Redirect("http://dotnet.aspx.cc");
}
</script>
<html xmlns="http://www.w3.org/1999/xhtml">
<head id="Head1" runat="server">
<title></title>
</head>
<body id="b" runat="server">
<form id="form1" runat="server">
<asp:Button ID="Button1" runat="server" OnClick="Button1_Click" Text="打开新窗口或者新 Tab " />
</form>
</body>
</html>
办法二:采用客户端脚本的方法设置 target 属性。代码如下:
<%@ Page Language="C#" AutoEventWireup="true" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<script runat="server">
protected void Page_Load(object sender, EventArgs e)
{
Button1.Attributes.Add("onclick", "this.form.target='_newName'");
}
protected void Button1_Click(object sender, EventArgs e)
{
Response.Redirect("http://dotnet.aspx.cc");
}
</script>
<html xmlns="http://www.w3.org/1999/xhtml">
<head id="Head1" runat="server">
<title></title>
</head>
<body id="b" runat="server">
<form id="form1" runat="server">
<asp:Button ID="Button1" runat="server" OnClick="Button1_Click" Text="打开新窗口或者新 Tab " />
</form>
</body>
</html>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<script runat="server">
protected void Page_Load(object sender, EventArgs e)
{
Button1.Attributes.Add("onclick", "this.form.target='_newName'");
}
protected void Button1_Click(object sender, EventArgs e)
{
Response.Redirect("http://dotnet.aspx.cc");
}
</script>
<html xmlns="http://www.w3.org/1999/xhtml">
<head id="Head1" runat="server">
<title></title>
</head>
<body id="b" runat="server">
<form id="form1" runat="server">
<asp:Button ID="Button1" runat="server" OnClick="Button1_Click" Text="打开新窗口或者新 Tab " />
</form>
</body>
</html>
上面两种方法中的 target 属性可以采用任何合法的名称,但要注意,如果相同名称的窗口已经打开,则新窗口会在已经存在名称的窗口里打开。
更新:如果需要设置弹出窗口的宽度和高度,可以修改为下面的方法:
<%@ Page Language="C#" AutoEventWireup="true" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<script runat="server">
protected void Page_Load(object sender, EventArgs e)
{
string WindowName = "win" + System.DateTime.Now.Ticks.ToString();
Page.RegisterOnSubmitStatement("js", "window.open('','" + WindowName + "','width=600,height=200')");
form1.Target = WindowName;
}
protected void Button1_Click(object sender, EventArgs e)
{
Response.Redirect("http://dotnet.aspx.cc");
}
</script>
<html xmlns="http://www.w3.org/1999/xhtml">
<head id="Head1" runat="server">
<title></title>
</head>
<body id="b" runat="server">
<form id="form1" runat="server">
<asp:Button ID="Button1" runat="server" OnClick="Button1_Click" Text="打开新窗口或者新 Tab " />
</form>
</body>
</html>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<script runat="server">
protected void Page_Load(object sender, EventArgs e)
{
string WindowName = "win" + System.DateTime.Now.Ticks.ToString();
Page.RegisterOnSubmitStatement("js", "window.open('','" + WindowName + "','width=600,height=200')");
form1.Target = WindowName;
}
protected void Button1_Click(object sender, EventArgs e)
{
Response.Redirect("http://dotnet.aspx.cc");
}
</script>
<html xmlns="http://www.w3.org/1999/xhtml">
<head id="Head1" runat="server">
<title></title>
</head>
<body id="b" runat="server">
<form id="form1" runat="server">
<asp:Button ID="Button1" runat="server" OnClick="Button1_Click" Text="打开新窗口或者新 Tab " />
</form>
</body>
</html>
