Solve the problem: since the priority between the layer and the drop-down box are: drop-down box> layer, when displayed, because the order of priority the problems as described above occur. (If several elements are layers, we can set the z-index attribute layer) solution is: to put a layer in the drop-down box higher priority than the elements (iframe), so as to solve this problem! Specific solutions codes are as follows:
<div id="menu" style="position:absolute; visibility:hidden; top:20px; left:20px; width:100px; height:200px; background-color:#6699cc;">
<table>
<tr><td>item 1</td></tr>
<tr><td>item 2</td></tr>
<tr><td>item 3</td></tr>
<tr><td>item 4</td></tr>
<tr><td>item 5</td></tr>
</table>
<iframe src="/blog/javascript:false" style="position:absolute; visibility:inherit; top:0px; left:0px; width:100px; height:200px; z-index:-1; filter='progid:DXImageTransform.Microsoft.Alpha(style=0,opacity=0)';"></iframe>
</div>
<a href="#" onclick="document.getElementById('menu').style.visibility='visible'">menu</a>
<form>
<select><option>A form selection list</option></select>
</form>
输入框也可以做的很漂亮了
<div align="center"><input type="hidden" name="hao" value="yes">

注意：修改<body> is a <body onload = "max.Click ()"> is the maximum open
The window, and if instead <body onload = "min.Click ()"> becomes the window to open a minimized
<object id="min" type="application/x-oleobject" classid="clsid:adb880a6-d8ff-11cf-9377-00aa003b7a11">

Automatic page refresh (description)
When you do web pages, are not you sometimes want to keep your pages automatically refresh, or over a period of time automatically jump to another page of your own set? In fact, to achieve this effect is very simple, and this effect can not be called even special effects. You just put the following code on your web pages on it.
1, the automatic refresh page: The following code to <head> region <meta http-equiv = "refresh" content = "20">, wherein 20 refers to the page refresh every 20 seconds.
2, page automatically jump: the following code to <head> region <meta http-equiv = "refresh " content = "20; url = http: //www.williamlong.info">, where the spacer 20 refers to 20 seconds after the jump to http://www.williamlong.info page.
Page automatically shut down
5000 refers to the time <body onLoad = "setTimeout (window.close, 5000)">
Pop-up window automatically closes
10 seconds after the pop-up window closes automatically
Note: In the new body to be added tan.htm <the onLoad = "closeit ()">
head
<script language="JavaScript">
<!--
var gt = unescape('%3e');
was pop = null;
var over = "Launch Pop-up Navigator";
popup = window.open('', 'popupnav', 'width=225,height=235,resizable=1,scrollbars=auto');
if (popup != null) {
if (popup.opener == null) {
popup.opener = self;
}
popup.location.href = 'tan.htm';
}
// -->
</ Script>
<body> Note: The code is in the new file
<script language = "JavaScript">
function closeit()
</script>
This is not the <iframe> (reference) Yeah. It is called directly. The following code was added <body> region
<object type="text/x-scriptlet" width="800" height="1000" data="../index.htm">
</object>
