JS实现对表格的各行换色（代码案例）-前端--易笔记

项目中有时需要对表格进行隔行换色达到更加直观的作用。下面是代码案例（由于只是涉及页面前端所以开发工具为HBulider）:

<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>隔行换色</title>
<script>
function init(){
var len=document.getElementById("TB1").tBodies[0].rows.length;
// alert(len);
                for (var i=0;i<len;i++) {
                if (i%2==0) {
                document.getElementById("TB1").tBodies[0].rows[i].style.background="red";
                } else{
                document.getElementById("TB1").tBodies[0].rows[i].style.background="pink";


                }
                }
}
</script>
</head>
<body onload="init()">
<table id="TB1" border="1" width="100px" height="60" align="center">
<thead>
<tr>
<th>ID</th>
<th>姓名</th>
</tr>
</thead>
<tbody>
<tr>
<td>1</td>
<td>庄</td>
</tr>
<tr>
<td>2</td>
<td>张</td>
</tr>
<tr>
<td>3</td>
<td>王</td>
</tr>
</tbody>
</table>
</body>
</html>
