高考问答怎么控制qq骰子点数:用javascript写一个简单的程序
来源：百度文库 编辑：高考问答 时间：2024/04/28 02:48:40
建立一个一行三列的表格,当鼠标停在第一行时,第三行显示"abcd",当鼠标停在第二行时,第三行显示"1234",当鼠标停在第三行时,第三行显示"这是第三行".
<table>
<tr onmouseover="ss.innerHTML='abcd';"><td>第一行</td></tr>
<tr onmouseover="ss.innerHTML='1234';"><td>第二行</td></tr>
<tr><td id=ss></td></tr>
</table>
onmouseover事件在鼠标放在单元格上时被激发。
ss.innerHTML='abcd'使id为ss的第三行单元格的内容变为abcd。
明白了没？
<table width="200" border="1">
<tr onmouseover="gogo.innerHTML='abcd';"><td>第一行</td></tr>
<tr onmouseover="gogo.innerHTML='1234';"><td>第二行</td></tr>
<tr><td id="gogo" onmouseover="this.innerHTML='这是第三行';">第三行</td></tr>
</table>

我的原理:是用层来做!就有点像JS的下拉菜单
btok的方法是不是还得加个onmouseout事件啊？
莫名其妙，这么简单的东西 用得着写这么多代码吗？？？
td中有onmouseover 和 onmouseout 事件 再追加上显示文字就ok了
