比較高效的表格行背景變色及選定高亮JS下面這個例一摘錄自：
http://blog.breakn.net/article.asp?id=447
例一：
//點擊當前選中行的時候設定當前行的顏色，同時恢複除當前行外的行的顏色及滑鼠事件
function selectRow(target)
{
var sTable = document.getElementById("ServiceListTable")
for(var i=1;i<sTable.rows.length;i++) //遍曆除第一行外的所有行
{
if (sTable.rows[i] != target) //判斷是否當前選定行
{
sTable.rows[i].bgColor = "#ffffff"; //設定背景色
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 = ""; //去除滑鼠事件
sTable.rows[i].onmouseout = ""; //去除滑鼠事件
}
}
}
//移過時tr的背景色
function rowOver(target)
{
target.bgColor='#e4e4e4';
}
//移出時tr的背景色
function rowOut(target)
{
target.bgColor='#ffffff';
}
//恢複tr的的onmouseover事件配套調用函數
function resumeRowOver()
{
rowOver(this);
}
//恢複tr的的onmouseout事件配套調用函數
function resumeRowOut()
{
rowOut(this);
} 頁面測試表格： <table width="100%" border="0" cellspacing="0" cellpadding="0" id="ServiceListTable">
<tr>
<th>服務事項</th>
<th>N</th>
<th>狀態</th>
<th>辦結</th>
<th>資料</th>
</tr>
<tr onmouseover="rowOver(this)" onmouseout="rowOut(this)" onclick="selectRow(this)">
<td>相關內容</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>相關內容</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>相關內容</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>相關內容</td>
<td align="center"> </td>
<td align="center"> </td>
<td align="center"> </td>
<td align="center"> </td>
</tr>
</table> 例二：
上述為Row中添加效果，做適當修改，為每個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>
<body>
