How to fill multidimensional array in javascript?

I tried to get this to work, but the outer loop stops after second iteration, and everything that's after it does not execute(just like it was the end of the script). I want to fill two dimensional array with any character(here i used 'q' as an example)

var A=[[],[]];

for(var i=0;i<12;i++){

    for(var j=0;j<81;j++){

        A[i][j]='q';

    }

}

It didn't work, so i put alert(i+' '+j); to see if it's even executing, and, as i wrote before, it stops after second iteration of outer loop, and then ignores rest of the script.

All I want is to have this array filled with same character in the given range(12 rows, 81 columns in this specific case), so if there's no hope in this method, i'll be glad to see one that works.

var A=[[], []];

^ This line declares a two dimensional array of size 1x2. Try this instead:

var A = [];

for (var i = 0; i < 12; i++) {

    A[i] = [];

    for (var j = 0; j < 81; j++) {

        A[i][j] = 'q';

    }

}
