为什么无法输出呢？

    <!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 myarr =new Array();

    for(var i=0;i<=2;i++){

        myarr[i]= new Array();

        for( var j=0;j<=5;j++){

            myarr[i][j]=i*j;

            document.write(myarr[i][j]+"</br>");

        }
        
        var myarr2 =[[0,0,0,0,0,0],[0,1,2,3,4,5],[0,2,4,6,10]];

    }

    改过后的代码

    document.write(myarr.[i][j]+"</br>");  </br>加双引号;

    var myarr[i]=new Array 改为 myarr[i]= new Array();
