这篇文章为大家分享了javascript实现表格隔行换色的代码，文中示例代码介绍的非常详细，零基础也能参考此文章，感兴趣的小伙伴们可以参考一下。
首先我们来看一下实现的效果，如下图所示：
思路：
确定事件: 文档加载完成 onload 2. 事件要触发函数: init() 3. 函数:操作页面的元素 要操作表格中每一行 动态的修改行的背景颜色
具体代码：
计算
安全
数据库
网络和加速
企业服务
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Title</title>
<script >
function init(){
//得到表格
var tab = document.getElementById("tab");
//得到表格中每一行
var rows = tab.rows;
//便利所有的行,然后根据奇数 偶数
for(var i=1; i < rows.length; i++){
var row = rows[i]; //得到其中的某一行
if(i%2==0){
row.bgColor = "yellow";
}else{
row.bgColor = "red"
}
}
}
</script>
</head>
