<!DOCTYPE HTML>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<title>二维数组</title>
<script type="text/javascript">
var appmy;
appmy=[["*","###","***","###","****","###"],
["**"]]
document.write("数组数量是:" + appmy.length + '<br>');
document.write(appmy[0][0] + '<br>' + appmy[1][0] + '<br>' +appmy[0][2] +'<br>' + appmy[0][4]);
</script>
</head>
<body>
