<!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<3;i++) { myarr[i]=new Array(); for (var j=0;j<6;j++) { myarr[i][j]=i+j; document.write("myarr[i][j]"); } } //document.write(myarr); </script> </head> <body> </body> </html>
把14行改成document.write(myarr[i][j]);
你多加了双引号,变成了字符串
document.write(“myarr[i][j]”)改成document.write(myarr[i][j])无双引号
