我的任务
分享菜单和层的(高难度)问题
我把网页做成框架（上：120rows 下：*），我在上边的网页上作了一个动态菜单，是用层实现的，当我点击了菜单的一项，即更新下面的网页。但我的弹出菜单会很长（如：顶级是：文件，编辑，查看。。。在点击了文件后会弹出：新建，打印，保存，另存为，打开，发送，关闭）这样的话层的高度会高出上边的网页的高度，则会出现：菜单项-〉打开，发送，关闭。为不可见的（这个位置显示了下边网页的内容）。怎样解决？
也即：让层能显示在其他网页内容的上方，在鼠标离开后层就消失，显示原来网页的内容。？？？？？？多谢了！

嘻嘻，xxrl(孔曰成仁，孟曰取E) 又被我的一堆帮助文件压在下面了，而且是英文的，是不是感觉有点喘不过来气啊？

这个问题前一阶段的大讨论,证明没有结果,只能用子框架的形式进行设计

WIDTH=n
>
Parameter Description
ALIGN=ABSBOTTOM | ABSMIDDLE | BASELINE | BOTTOM | LEFT | MIDDLE | RIGHT | TEXTTOP | TOP Specifies the alignment for the control-like element.
BORDER=pixels Specifies the thickness of a border to be drawn around the element. The default is 0.
BORDERCOLOR=color Sets border color and must be used with the BORDER attribute, except for frames. For a complete list of colors, look at the Internet Explorer color table.
CLASS=classname Specifies the class of the tag being defined. This is used to associate a sub-classed style sheet with the tag.
DATAFLD=colname The column name from the data source object that supplies the bound data.
DATASRC=#ID Indicates the ID of the data source object that supplies the data that is bound to this element.
FRAMEBORDER=NO | YES | 0 | 1 Specifies whether or not to display a 3-D border around the frame. "YES" or 1 causes a border to be displayed (default). "NO" or 0 displays no border.
FRAMESPACING=pixels Creates additional space between the frames.
HEIGHT=n Along with WIDTH, specifies the size at which the element is drawn. This attribute may be initially set in pixels or percentages.
HSPACE=pixels Along with VSPACE, specifies margins for the element.
ID=value An SGML identifier used as the target for hypertext links or for naming particular elements in associated style sheets. Valid ID values must begin with a letter. The underbar character, "_", may be used in the ID name. The ID should be unique throughout the scope of the document. If more than one object with the same identifier exists in a document, a collection of those named items is created that can only be referenced by ordinal position.
LANG=language Specifies which language to use in ISO standard language abbreviation form.
LANGUAGE=JAVASCRIPT | JSCRIPT | VBS | VBSCRIPT Specifies the language the current script is written in and invokes the proper scripting engine. The default value is JAVASCRIPT. JAVASCRIPT, JSCRIPT The scripting language is written in JavaScript.
VBS, VBSCRIPT The scripting language is written in VBScript.
MARGINHEIGHT=pixels Sets the amount of top and bottom margin should be set before displaying the text in a frame.
MARGINWIDTH=pixels Sets the amount of left and right margin should be set before displaying the text in a frame.
NAME=window_name | _blank | _parent | _self | _top Specifies the window or frame to target the contents at. If no frame or window exists that matches the specified target, a new window is opened for the specified link. If no target is specified, the default is "_self" for a link within the same site or "_top" if the site is external. Special target values are listed below: _blank Specifies to load the link into a new unnamed window.
_parent Specifies to load the link into the immediate parent of the document the link is in.
_self Specifies to load the link into the same window the link was clicked in.
_top Specifies to load the link into the full body of the current window.
NORESIZE When this attribute is supplied, the frame is not resizable by the user. The default behavior allows the user to resize the frame.
SCROLLING=AUTO | NO | YES Specifies that the frame can be scrolled. If set to "AUTO," the browser determines whether scrollbars are necessary (default).
SRC=url Specifies a URL for the associated file to be displayed in the frame.
STYLE=css1-properties Specifies an in-line style sheet for the tag.
TITLE=text Used to provide advisory information.
VSPACE=pixels Along with HSPACE, specifies margins for the element.
WIDTH=n Along with HEIGHT, sets the initial size of the element. This attribute may be initially set in pixels or percentages.
Remarks
This element is a block element.
Both the start and end tags are required.

晕！
既然是菜单

不要用框架了。

现在不是怎么让层出现的问题，而是怎么让层浮在网页其他内容的上面，甚至其他网页的上面（框架内），

采用onmouse事件
把层设置成hide
菜单栏onmouse=show
内容部分onmouse=hide

把你的层用iframe替代才可以。
层在IE5.0会被框架挡住，
如果你不想改层的话，只能采用隐藏下面框架页的方式了。
也就是你显示下拉菜单时，将下面的框架页隐藏。
