为什么我的输不出
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<title>二维数组</title>
<script type="text/javascript">
var myarr = new Array();
for(var i = 0; i < 2; i++){
myarr[i] = new Array();
for(var j = 0; j < 5; j++){
mayarr[i][j] = i * j;
document.write(myarr[i][j]);
}
}
</script>
</head>
<body>
</body>
</html>
mayarr[i][j] = i * j;
数组名多了一个"a"，应该是myarr
