只要在Layer中再插Iframe 或 Object 设z-Index值
HTML 代码片段如下:
<div z-Index:2><object xxx></object></div> ＃ 前面
<div z-Index:1><object xxx></object></div> ＃ 后面
<div id="Layer2" style="position:absolute; top:40;width:400px; height:95px;z-index:2"><table height=100% width=100% bgcolor="#ff0000"><tr><td height=100% width=100%></td></tr></table><iframe width=0 height=0></iframe></div>
<div id="Layer1" style="position:absolute; top:50;width:200px; height:115px;z-index:1"><iframe height=100% width=100%></iframe></div>

解释一下event.X和event.clientX有什么区别
JS/AJAX 49 views, No Comments
event.clientX返回事件发生时,mouse相对于客户窗口的X坐标
event.X也一样
但是如果设置事件对象的定位属性值为relative
event.clientX不变
而event.X返回事件对象的相对于本体的坐标
event代表事件的状态，例如事件发生的的元素、鼠标的位置等等，event对象只在事件过程中才有效。
event属性：
altKey
检索ALT键的当前状态
可能的值 true为关闭
false为不关闭
button
检索按下的鼠标键
可能的值： 0 没按键
1 按左键
2 按右键
3 按左右键
4 按中间键
5 按左键和中间键 更多详细内容 »
