本文积累了几种鼠标移入或者移出html的table表格时,表格背景色变化的几种方法。
一、利用样式CSS表达式
在样式里写表达式expression,实现鼠标经过表格行上变色,但在firefox里无效果。
完整代码如下:
<html>
<head>
<title>在样式里写表达式expression,实现鼠标经过表格行上变色</title>
<style type="text/css">
.tbDatalist
{
border: 1px solid #007108;
width: 60%;
border-collapse: collapse; /* 边框重叠,cell间没有空隙 */
background-color: #d9ffdc;
}
.tbDatalist th
{
border: 1px solid #007108;
background-color: #00a40c;
color: #ffffff;
font-weight: bold;
padding: 4px 12px 4px 12px; /* 上 右下左 */
text-align: center;
}
.tbDatalist td
{
border: 1px solid #007108;
text-align: left;
padding: 4px 10px 4px 10px /* 上 右下左 */;
/* 如果去掉tbDatalist tr里的代码,而增加下面的代码。则实现鼠标经过单元格上,此单元格变色
onmouseover:expression(onmouseover=function(){this.style.backgroundColor='orange'});
onmouseout:expression(onmouseout=function(){this.style.backgroundColor='#d9ffdc'});
*/
}
.tbDatalist tr
{
onmouseover:expression(onmouseover=function(){this.style.backgroundColor='#a5e5aa'});
onmouseout:expression(onmouseout=function(){this.style.backgroundColor='#d9ffdc'});
}
</style>
</head>
<body>
<table class="tbDatalist" summary="list of members in EE Studay" id="oTable">
<tr>
<th scope="col">姓名</th>
<th scope="col">班级</th>
<th scope="col">出生日期</th>
<th scope="col">星座</th>
<th scope="col">电话</th>
</tr>
<tr>
<td>slepox</td>
<td> W19</td>
<td>Nov 18th</td>
<td>Scorpio</td>
<td>0658635</td>
</tr>
<tr>
<td>smartlau</td>
<td>W19</td>
<td>Dec 30th</td>
<td>Capricorn</td>
<td>0006621</td>
</tr>
</table>
</body>
</html>
二、利用jquery的hover(fun,fun)方法
利用jquery的hover(fun,fun)方法,实现鼠标经过表格行上变色,hover()方法有两个参数,第一个参数为鼠标移到某行上要执行的方法,相当于onmouseover(),第2个事参数是鼠标离开某行后要执行的方法,相当于onmouseout()。
完整代码如下:(jquery-1.4.1-vsdoc.js)为VS.NET2010自带的JQuery包
<html>
<head>
<title>利用jquery的hover(fun,fun)方法,实现鼠标经过表格行上变色</title>
<script src="../Scripts/jquery-1.4.1-vsdoc.js" type="text/javascript"></script>
<style type="text/css">
.tbDatalist
{
border: 1px solid #007108;
width: 60%;
border-collapse: collapse; /* 边框重叠,cell间没有空隙 */
background-color: #d9ffdc;
}
.tbDatalist th
{
border: 1px solid #007108;
background-color: #00a40c;
color: #ffffff;
font-weight: bold;
padding: 4px 12px 4px 12px; /* 上 右下左 */
text-align: center;
}
.tbDatalist td
{
border: 1px solid #007108;
text-align: left;
padding: 4px 10px 4px 10px /* 上 右下左 */;
}
.tbDatalist tr.altrow
{
background-color: #a5e5aa;
}
</style>
<script type="text/javascript">
$(document).ready(function() {
$("tr").hover(
function() {
$(this).css("background", "#a5e5aa"); //鼠标移动上去的颜色
},
function() {
$(this).css("background", "#d9ffdc"); //鼠标离开的颜色
}
);
});
</script>
</head>
<body>
<table class="tbDatalist" summary="list of members in EE Studay" id="oTable">
<tr>
<th scope="col">姓名</th>
<th scope="col">班级</th>
<th scope="col">出生日期</th>
<th scope="col">星座</th>
<th scope="col">电话</th>
</tr>
<tr>
<td>slepox</td>
<td> W19</td>
<td>Nov 18th</td>
<td>Scorpio</td>
<td>0658635</td>
</tr>
<tr>
<td>smartlau</td>
<td>W19</td>
<td>Dec 30th</td>
<td>Capricorn</td>
<td>0006621</td>
</tr>
</table>
</body>
</html>
三、利用JS的onmouseover()方法和onmouseout()方法
利用JS的onmouseover()方法和onmouseout()方法,实现鼠标移动表格行上变色。
完整代码如下:
<html>
<head>
<title>利用JS,实现鼠标移动表格行上变色</title>
<style type="text/css">
.tbDatalist
{
border: 1px solid #007108;
width: 500;
border-collapse: collapse; /* 边框重叠,cell间没有空隙 */
background-color: #d9ffdc;
}
.tbDatalist th
{
border: 1px solid #007108;
background-color: #00a40c;
color: #ffffff;
font-weight: bold;
padding: 4px 12px 4px 12px; /* 上 右下左 */
text-align: center;
}
.tbDatalist td
{
border: 1px solid #007108;
text-align: left;
padding: 4px 10px 4px 10px /* 上 右下左 */;
}
</style>
<script type="text/javascript">
window.onload = function showTable() {
var tablename = document.getElementById("oTable");
var oRows = tablename.getElementsByTagName("tr");
for (var i = 0; i < oRows.length; i++) {
oRows[i].onmouseover = function() {
this.style.backgroundColor = "#a5e5aa";
}
oRows[i].onmouseout = function() {
this.style.backgroundColor = "#d9ffdc";
}
}
}
</script>
</head>
<body>
<table class="tbDatalist" summary="list of members in EE Studay" id="oTable">
<tr>
<th scope="col">姓名</th>
<th scope="col">班级</th>
<th scope="col">出生日期</th>
<th scope="col">星座</th>
<th scope="col">电话</th>
</tr>
<tr>
<td>slepox</td>
<td> W19</td>
<td>Nov 18th</td>
<td>Scorpio</td>
<td>0658635</td>
</tr>
<tr>
<td>smartlau</td>
<td>W19</td>
<td>Dec 30th</td>
<td>Capricorn</td>
<td>0006621</td>
</tr>
</table>
</body>
