为什么还没有移开div在区域内就响应onmouseout了
应该是div的鼠
标响应事件的问题，为什么还没有鼠标移开div在区域内就响应onmouseout了
这是两个层，鼠标放底下层后，弹出详细层，将低层覆盖，现在问题是，
为什么还没有鼠标移开div在区域内就响应onmouseout了
  <div   id= "menu2 "   class= "plist "   onmouseover= "over_forshow(this,   'showdetails2 ') "     />

</div>

<div   id= "showdetails2 "       class= "plist2 "     onmouseout= "over_forshowclose( 'showdetails2 '); "   > </div>

这个应该和你问的问题类似吧。

如果 (event.fromElement!=event.toElement) && (this.contains(event.toElement) )
就触发onmouseover事件一次
如果 (event.fromElement!=event.toElement) && (this.contains(event.fromElement) )
就触发onmouseout事件一次

如果 (!this.contains(event.fromElement)) && (this.contains(event.toElement) )
就触发onmouseenter事件一次

如果 (!this.contains(event.toElement)) && (this.contains(event.fromElement) )
就触发onmouseleave事件一次
