在前端開發中常常見到隔行變色鼠標移入高亮顯示的效果,下面小編給你們分享基於js代碼實現的隔行變色鼠標移入高亮效果,廢話很少說了,具體代碼以下所示:javascript
<!DOCTYPE html>
css
<html>
html
<head>
前端
<meta charset=
"UTF-8"
>
java
<title></title>
this
<style type=
"text/css"
>
code
#table {
htm
width: 400px;
seo
border-collapse: collapse;
ip
}
</style>
</head>
<body>
<table id=
"table"
border=
"1"
>
<thead>
<td>ID</td>
<td>姓名</td>
<td>年齡</td>
</thead>
<tbody>
<tr>
<td>1</td>
<td>黃藝</td>
<td>20</td>
</tr>
<tr>
<td>2</td>
<td>張三</td>
<td>21</td>
</tr>
<tr>
<td>3</td>
<td>李四</td>
<td>22</td>
</tr>
<tr>
<td>4</td>
<td>網無</td>
<td>23</td>
</tr>
</tbody>
</table>
</body>
<script type=
"text/javascript"
>
// 實現隔行變色,鼠標移入高亮
var
table = document.getElementById(
"table"
);
var
oldColor =
""
;
//聲明一個變量,保存表格原來的顏色
for
(
var
i = 0; i < table.tBodies[0].rows.length; i++) {
//使用判斷實現隔行變色
if
(i % 2 == 0) {
table.tBodies[0].rows[i].style.backgroundColor =
"gray"
;
}
else
{
table.tBodies[0].rows[i].style.backgroundColor =
"#ccc"
;
}
//實現鼠標移入高亮
table.tBodies[0].rows[i].onmouseover =
function
() {
oldColor =
this
.style.backgroundColor;
this
.style.backgroundColor =
"red"
;
}
//實現鼠標移出變回原來的顏色
table.tBodies[0].rows[i].onmouseout =
function
() {
this
.style.backgroundColor = oldColor;
}
}
</script>
