# of values in arrays

[ccy1234]

How do I find the number of values in an array?

thanks.

The simple answer is that it's held in the array's

[blue]length[/blue]

property.

The first complication comes when you consider that an array may have undefined values. Then you consider that JS arrays are really little more than collections of name/value pairs. It is possible for arrays to have non-contiguous, non-integer, or negative indices, or indices that aren't numbers.

All told, the solution depends very much on the exact nature of the question.

When all else fails -- you can always loop through it and use a vanilla counting method
