1、iframe自適應頁面高度
<script type="text/javascript">
function TuneHeight() {
var frm = document.getElementById("PhotoIframe");
var subWeb = document.frames ? document.frames["PhotoIframe"].document : frm.contentDocument;
if (frm != null && subWeb != null) {
frm.height = subWeb.body.scrollHeight;
}
}
<html>
<head></head>
<body>
<form id="form1" runat="server">
<div>
<table cellpadding="0" cellspacing="0" width="100%" style=" border:0;">
<tr>
<td class="title">標題</td>
<td rowspan="2" valign="top" style=" width:270px; padding-left:5px; padding-right:5px;">
<iframe id="PhotoIframe" marginheight="0" marginwidth="0" scrolling="no" frameborder="0" width="260" runat="server"></iframe>
</td>
</tr>
<tr>
<td valign="top" style=" border-top:0px; height:expression(this.parentElement.parentElement.rows[0].cells[1].clientHeight - 35);" >
<div id="info_div" runat="server">
<table cellpadding="0" cellspacing="0" class="atable">
<tr class="gay">
<td colspan="3" class="td_lbl">
<!--姓名：--><asp:Label ID="lblReserver1_Info" runat="server" Text=""></asp:Label>
<!--職務：--><asp:Label ID="lblReserver2_Info" runat="server" Text=""></asp:Label>
<!--證件名稱：--><asp:Label ID="lblReserver3_Info" runat="server" Text=""></asp:Label>
<!--證件號碼：--><asp:Label ID="lblReserver4_Info" runat="server" Text=""></asp:Label>
</td>
</tr>
</table>
<div id="info_btn" class="div_btn">
<asp:Button ID="btnUpdate" runat="server" Text="修 改" οnclick="btnUpdate_Click" CssClass="btn" />
<asp:Button ID="btnPrint" runat="server" Text="打 印" οnclick="btnPrint_Click" CssClass="btn" />
<asp:Button ID="btnBack" runat="server" Text="返 回" οnclick="btnBack_Click" CssClass="btn" />
</div>
</div>
</td>
</tr>
</table>
</div>
</form>
</body>
<html>
後臺：this.PhotoIframe.Attributes.Add("onload", "TuneHeight()");
2、以window.open()打開子窗口，關閉子窗口刷新父頁面
<script language=JavaScript>
window.opener.location.href=window.opener.location.href;
</script>
3、以window.showModalDialog()打開子窗口，關閉子窗口刷新父頁面
<script language=JavaScript>
window.parent.dialogArguments.document.execCommand('Refresh');
</script>
