October 31, 2000, 12:00 AM — Similar to one-dimensional arrays, you access the data in multi-
dimensional arrays in much the same way you assign data to multi-
dimensional arrays.
Accessing Data in a Two-Dimensional Array
Ready to create an array of stir-fry ingredients? Okay, here we go.
...
The array has been created and populated.
Now, let's access
the data.
This program prints all the elements of a two-dimensional array by
going through them with a while loop. Here's the code:
while (Count<=4)
{
document.write("
" + StirFry[Count][0] + ", which
is/are " + StirFry
[Count][1] + " in color.")
Count++
}
Access each of the elements in the two-dimensional array by a statement
like StirFry[Count][0]. Count is the element of StirFry
that's
relevant, while 0 or 1 is the number of the needed element in the array
that fills the Count space in StirFry.
You may find it helpful to think of Array[n][p]
references in terms of
coordinates: The first number is the "down" coordinate, while the
second coordinate is the "across" coordinate.
