鼠标悬停表格可见，鼠标移开表格隐藏

Question

<div onMouseOver="this.firstChild.style.visibility='visible'" 
onMouseOut="this.firstChild.style.visibility='hidden'" > <TABLE style="visibility:hidden"> <tr> <td>11111111111 </td> </tr> </table> 试试 </div> 这样就可以了

Answer 1

为什么呢？如何没有DIV，只有TABLE<TABLE style="visibility:hidden" onMouseOver="this.style.visibility='visible'" onMouseOut="this.style.visibility='hidden'" > <tr> <td>11111111111 </td> </tr> </table> 这样就不可能实现显示和隐藏的效果了吗?

Answer 2

visibility都是hidden了，怎么还能捕获onMouseOver
