<form id="WebForm9" method="post" runat="server">
<table align="center" width="800px">
<tr>
<td width="50%"><iframe id="tree.aspx" src="WebForm10.aspx"></iframe></td>
<td></td>
</tr>
</table>
</form>用 iframe
<table align="center" width="800px">
<tr>
<td width="50%"><iframe id="tree.aspx" src="WebForm10.aspx"></iframe></td>
<td></td>
</tr>
</table>
</form>用 iframe
response.write(<script>document.all.iframe.src='page.aspx';</script>)
绝对没问题...实际上就是让iframe内的页面慢于主页面load.
