<!DOCTYPE?HTML>

<meta?http-equiv="Content-Type"?content="text/html;?charset=utf-8">

<title>二維數(shù)組</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++){

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

????}

改過(guò)后的代碼

document.write(myarr.[i][j]+"</br>");? </br>加雙引號(hào);

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