用鼠标弹出隐藏层

下面为效果显示

脚本说明:
第一步：把如下代码加入<body>区域中
<STYLE>#slidemenubar {
	BACKGROUND-COLOR:#FF0000;BORDER-BOTTOM: #ffffff 1px solid; BORDER-LEFT: #ffffff 1px solid; BORDER-RIGHT: #ffffff 1px solid; BORDER-TOP: #ffffff 1px solid;  FONT: bold 12px/20px Verdana; LEFT: -155px; POSITION: absolute; TOP: 10px; WIDTH: 200px; layer-background-color: #FFff00
}
#slidemenubar2 {
	BACKGROUND-COLOR: #FF0000; BORDER-BOTTOM: #ffffff 1px solid; BORDER-LEFT: #ffffff 1px solid; BORDER-RIGHT: #ffffff 1px solid; BORDER-TOP: #ffffff 1px solid;  FONT: bold 12px/20px Verdana; LEFT: -155px; POSITION: absolute; TOP: 10px; WIDTH: 200px; layer-background-color: #FFff00
}
.word {  font-size: 9pt; line-height: 13pt; color: #ffccdd}
.word1 {  font-size: 8pt; line-height: 13pt; color: #ffccdd}
</STYLE>

<font class="word"></font> 
<p><font color="#CCCCCC"></font> 
  
</p>
<div id="Layer2" style="position:absolute; left:439px; top:58px; width:227px; height:7px; z-index:2" class="word"> 
  <font color="#FF0000">请在网页任何地方点击鼠标左键弹出作品菜单，点击鼠标右键让作品菜单消失,X键和Z键也可以。</font></div>

第二步：把<body>中的代码改为：
<body   oncontextmenu=self.event.returnValue=false>
