我是靠谱客的博主平常彩虹，最近开发中收集的这篇文章主要介绍table对象中的insertRow与deleteRow使用示例，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

复制代码代码如下:

 
<!DOCTYPE html> 
<html> 
<head> 
<title>table1.html</title> 

<meta http-equiv="keywords" content="keyword1,keyword2,keyword3"> 
<meta http-equiv="description" content="this is my page"> 
<meta http-equiv="content-type" content="text/html; charset=UTF-8"> 

<!--<link rel="stylesheet" type="text/css" href="./styles.css">--> 
<script language = "javascript" type = "text/javascript"> 
<!-- 
function test1(){ 
//判断插入的编号是否已经存在 
for(var i=0;i<mytable.rows.length;i++){ 
var eachRow = mytable.rows[i]; 
if(eachRow.cells[0].innerText == no.value){ 
window.alert("编号已经存在！"); 
return ; 
} 
} 
//获取表单中的数据 
var newTableRow = mytable.insertRow(mytable.rows.length); 
newTableRow.insertCell(0).innerText = no.value; 
newTableRow.insertCell(1).innerText = name1.value; 
newTableRow.insertCell(2).innerText = nickName.value; 
} 

function test2(){ 
mytable.deleteRow(mytable.rows.length-1); 
} 
//--> 
</script> 
</head> 

<body> 
<h1>英雄排行榜</h1> 
<table id = "mytable" border = "1"> 
<tr><td>排名</td><td>姓名</td><td>外号</td></tr> 
<tr><td>1</td><td>宋江</td><td>及时雨</td></tr> 
<tr><td>2</td><td>卢俊义</td><td>玉麒麟</td></tr> 
</table> 
<h1>请输入新的好汉</h1> 
编号<input id = "no" type = "text" value = ""><br/> 
名字<input id = "name1" type = "text" value = ""><br/> 
外号<input id = "nickName" type = "text" value = ""><br/> 
<input id = "tianjia" type = "button" value = "添加" onclick = "test1()"> 
<input type = "button" value = "删除最后一行" onclick = "test2()"/> 
</body> 
</html>
