比较高效的表格行背景变色及选定高亮JS
下面这个例一摘录自：
http://blog.breakn.net/article.asp?id=447
例一：
页面测试表格：
例二：
上述为Row中添加效果，做适当修改，为每个Cell添加效果：
例三：
再做适当修改，实现鼠标点击Table单元格Cell的时候，最后两个被点击的Cell背景颜色被改变：

例一：
//点击当前选中行的时候设置当前行的颜色，同时恢复除当前行外的行的颜色及鼠标事件
function selectRow(target)
{
var sTable = document.getElementById("ServiceListTable")
for(var i=1;i<sTable.rows.length;i++) //遍历除第一行外的所有行
{
if (sTable.rows[i] != target) //判断是否当前选定行
{
sTable.rows[i].bgColor = "#ffffff"; //设置背景色
sTable.rows[i].onmouseover = resumeRowOver; //增加onmouseover 事件
sTable.rows[i].onmouseout = resumeRowOut;//增加onmouseout 事件
}
else
{
sTable.rows[i].bgColor = "#d3d3d3";
sTable.rows[i].onmouseover = ""; //去除鼠标事件
sTable.rows[i].onmouseout = ""; //去除鼠标事件
}
}
}
//移过时tr的背景色
function rowOver(target)
{
target.bgColor='#e4e4e4';
}
//移出时tr的背景色
function rowOut(target)
{
target.bgColor='#ffffff';
}
//恢复tr的的onmouseover事件配套调用函数
function resumeRowOver()
{
rowOver(this);
}
//恢复tr的的onmouseout事件配套调用函数
function resumeRowOut()
{
rowOut(this);
}
页面测试表格：
<table width="100%" border="0" cellspacing="0" cellpadding="0" id="ServiceListTable"> <tr> <th>服务事项</th> <th>N</th> <th>状态</th> <th>办结</th> <th>资料</th> </tr> <tr onmouseover="rowOver(this)" onmouseout="rowOut(this)" onclick="selectRow(this)"> <td>相关内容</td> <td align="center"> </td> <td align="center"> </td> <td align="center"> </td> <td align="center"> </td> </tr> <tr onmouseover="rowOver(this)" onmouseout="rowOut(this)" onclick="selectRow(this)"> <td>相关内容</td> <td align="center"> </td> <td align="center"> </td> <td align="center"> </td> <td align="center"> </td> </tr> <tr onmouseover="rowOver(this)" onmouseout="rowOut(this)" onclick="selectRow(this)"> <td>相关内容</td> <td align="center"> </td> <td align="center"> </td> <td align="center"> </td> <td align="center"> </td> </tr> <tr onmouseover="rowOver(this)" onmouseout="rowOut(this)" onclick="selectRow(this)"> <td>相关内容</td> <td align="center"> </td> <td align="center"> </td> <td align="center"> </td> <td align="center"> </td> </tr> </table>
