用JS生成动态生成表格，行、列由用户输入，并使表格隔行换色
方法一.
代码:
<!DOCTYPE html>
<html>
<head>
<title>动态表格</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" rel="external nofollow" rel="external nofollow" >-->
<script type="text/javascript">
function createTable(){
var table = document.createElement("table");
//添加边框
table.border = "1";
table.width = "100%";
//table API
//创建一行
//var tr = table.insertRow(table.rows.length);
//创建单元格
//var td = tr.insertCell(tr.cells.length);
//行，单元格
var tr,td;
//获得行列值
var tr_value = document.getElementById("tr_value").value;
var td_value = document.getElementById("td_value").value;
for(var i=0;i<tr_value;i++){
//循环插入元素
tr = table.insertRow(table.rows.length);
if(i%2 === 0){
tr.style.backgroundColor = "#D5E3D0";
}else{
tr.style.backgroundColor = "#909C97";
}
for(var j=0;j<td_value;j++){
td = tr.insertCell(tr.cells.length);
td.innerHTML = "_";
td.align = "center";
}
}
//td.innerHTML = "测试";
document.querySelector("#tb").appendChild(table);
}
</script>
</head>
<body>
<input type="text" id="tr_value">输入行数
<input type="text" id="td_value">输入列数
<input type="button" onclick="createTable()"； value="createTable">
<hr>
<div id="tb"></div>
</body>
</html>
运行结果:
输入行数、列数，create Table:
