Default.aspx
protected void Page_Load(object sender, EventArgs e)
{
Response.Redirect("WebForm1.aspx");
}
<body>
<form id="form1" runat="server">
<div>
<iframe src="About.aspx"></iframe>
</div>
</form>
</body>About.aspx
<asp:Content ID="HeaderContent" runat="server" ContentPlaceHolderID="HeadContent">
<script language="javascript" type="text/javascript">
function Button2_onclick() {
window.open('WebForm2.aspx', 'newwindow', 'height=600,width=600,top=0,left=0,toolbar=no,menubar=no,scrollbars=no, resizable=no,location=no, status=no');
top.opener = null;
top.close(); //注意, 不可跨域
}
</script>
</asp:Content>
<asp:Content ID="BodyContent" runat="server" ContentPlaceHolderID="MainContent">
<h2>
关于
<input id="Button2" type="button" value="button" οnclick="return Button2_onclick()" /></h2>
<p>
将内容放置在此处。
</p>
</asp:Content>
这样就可以预览Default.aspx时展示Webform1.aspx,这时点击位于iframe中About.aspx的Button2即可跳转到WebForm2.aspx(已经没有iframe了)
