how to make 2D arrays in javascript

[Red Squirrel]

A basic way to make a 2D array 20 by 20 is like this:

Code: Select all

var UserBoard = new Array(20);

for(var i=0;i<=21;i++)
{
UserBoard[i]==new Array(20);
}

UserBoard[4,5]="test";
alert("test:" + UserBoard[4,5]);
[code]

Reason I'm posting this is just for reference purposes since I've been trying to do this for hours, thinking it was UserBoard[4][5] but it's UserBoard[4,5] that you access it by.
