Multi-Dimensional Array

    I have an array, called, "myArray". Inside this myArray are 4 more arrays, "m0, m1, m2, m3".
    How do I access all the elements in all the array?

    Here's my code, :
    <!DOCTYPE html>
<html>
<head>
    <title></title>
</head>

<body>
<script>
var m0 = [0, 1, 2, 3, 4];
var m1 = [5, 6, 7, 8, 9];
var m2 = [10, 11, 12, 13, 14];
var m3 = [15, 16, 17, 18, 19];

var myArray = [m0, m1, m2, m3];


for (var i = 0; i < myArray.length; i++) {
    for (var j = 0; j < ("m"+i).length; j++) {
        document.writeln(myArray[i][j]);
    }
}
</script>
</body>
</html>
    Code (markup):

    This code only give me the first 2 elements in each array.
    But, I would like to get all the elements in all the arrays.

    tks

    here is your solution:
    for (var i = 0; i < myArray.length; i++) {
    for (var j = 0; j < myArray.length; j++) {
    document.writeln(myArray[j]);
    }
    }

    instead of ("m"+i).length myArray would do what you are looking for ;)

    for (var i = 0; i < myArray.length; i++) {
    for (var j = 0; j < myArray [ i ].length; j++) {
    document.writeln(myArray [ i ][j]);
    }
    }
