二位数组的输入输出
<!DOCTYPE html>

<head>
<meta charset="UTF-8">

<script language="JavaScript" type="text/jscript">
var arr = [
[1, 2, 4, 6],
[2, 4, 7, 8],
[8, 9, 10, 11],
[9, 12, 13, 15]
];
for(var i = 0; i < arr.length; i++) {
for(var j = 0; j < arr[i].length; j++) {
document.write(arr[i][j]);
}
document.write("<br/>");
}
</script>

开始老是错误的代码：
为啥错误？将docunent.write 写作 window.write 应该是window.alert();
