ArrayDeleteAt |
Description
Deletes an element from an array.
When an element is deleted, ColdFusion recalculates index positions. For example, in an array that contains the months of the year, deleting the element at position 5 removes the entry for May. After this, to delete the entry for June, you would delete the element at position 5 (not 6).
Returns
True, on successful completion.
