The following code always returns a value of 3 on my Mac. How can I have my script return "4"?

var test = new Array()
test[1,1] = "1"
test[1,2] = "2"
test[2,1] = "3"
test[2,2] = "4"
test[3,1] = "5"
test[3,2] = "6"
test[4,1] = "7"
test[4,2] = "8"
document.write(test.length)
</script>

Multidimensional arrays are accessed as array[x][y], not array[x,y]. The comma operator works as follows: if you have x,y it returns y. So, array[x,y] is the same as array[y]. That's why you have only 3 elements - you set 1 and 2 repeatedly. Also, remember that arrays are 0 based.

It should work, thanks.
