asp教程.net Response.Redirect跳出框架与打开窗口方法
跳出框架大概会用到js top.location来实现。
Response.Write('<script>top.location='http://www.111cn.net';</script>');
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='url';</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
<%@ 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>
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://www.111cn.net");
}
</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>
