用sun的ftp包連接IBM aix服務器拋如下錯誤：
501 port not allow after EPSV ALL, active mode off
原因：
ftp要改為被動passtive模式.
解決方法：
使用第三方包edtftpj-1.5.1.jar連接服務器，在連接前設置模式為passtive

Bug描述： SELECT elements ignore Z-index ("windowed element" problem)
連接：http://www.throbs.net/web/articles/IE-SELECT-bugs/#ieZIndex
問題原因：
1. select html標記在IE6下的解析不管Z-index
2. div 不能遮蓋select,
解決思路:
1. 在select上用iframe遮蓋
2. 在iframe上用div遮蓋
3. iframe的width,height,top,left與div一樣大.
示例代碼
#zindexDiv{
position:absolute;
z-index:50;
width:expression(this.nextSibling.offsetWidth);
height:expression(this.nextSibling.offsetHeight);
top:expression(this.nextSibling.offsetTop);
left:expression(this.nextSibling.offsetLeft);
/*background-color:green;?ff????????,????????????????*/
}
#divUp{
z-index:99;
position:absolute;
background-color:red;
width:100;
height:18;
overflow:hidden;
height:60px;
}
#ddlTest{
width:200;
z-index:1;
}
</style>
<body>
<iframe id="zindexDiv" frameborder="0"></iframe>
<div id="divUp">aaaaaaa<br>bbbbbbb<br>ccccccc</div>

IE6下用
style="page-break-before: always"
可以打印分頁.
IE7下不行.這句css不起作用
需要加上這句css
<!--[if IE 7]><br style="height:0; line-height:0"><![endif]-->
全部的css
<div style="page-break-before: always;">
<!--[if IE 7]><br style="height:0; line-height:0"><![endif]-->
</div>
