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：
//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：

例二：
上述为Row中添加效果，做适当修改，为每个Cell添加效果：

<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<title>Test</title>
<script language="javascript">
function selectCell(target) {
  var sTable = document.getElementById("table1")
  for(var i=0;i<sTable.rows.length;i++) {
   for(var j=0; j<sTable.rows[i].cells.length; j++) {
    if (sTable.rows[i].cells[j] != target) {
     sTable.rows[i].cells[j].bgColor = "#ffffff";
     sTable.rows[i].cells[j].onmouseover = resumeCellOver;
     sTable.rows[i].cells[j].onmouseout = resumeCellOut;
    }
    else {
     sTable.rows[i].cells[j].bgColor = "#d3d3d3";
     sTable.rows[i].cells[j].onmouseover = "";
     sTable.rows[i].cells[j].onmouseout = "";
    }
   }
  }
}

function cellOver(target) {
  target.bgColor='#e4e4e4';
}

function cellOut(target) {
  target.bgColor='#ffffff';
}

function resumeCellOver() {
  cellOver(this);
}

function resumeCellOut() {
  cellOut(this);
}
</script>
</head>
