Array.sortOn() 119
// barb
// abcd
Performing a default sort on the age field produces the following results:
my_array.sortOn("age");
// 29
// 3
// 35
// 4
Performing a numeric sort on the age field produces the following results:
my_array.sortOn("age", 16);
// 3
// 4
// 29
// 35
Performing a descending numeric sort on the age field produces the following results:
my_array.sortOn("age", 18);
// 35
// 29
// 4
// 3
Performing a sort changes the elements in the array produces the following results:
// Before sorting
// my_array[0].age = 29;
// my_array[1].age = 3;
// my_array[2].age = 35;
// my_array[3].age = 4;
// After any sort that doesn’t pass a value of 8 for option
my_array.sortOn("age", Array.NUMERIC);
// my_array[0].age = 3;
// my_array[1].age = 4;
// my_array[2].age = 29;
// my_array[3].age = 35;
Performing a sort that returns an index array doesn’t change the elements in the array, as shown in
the following example:
// Before sorting
// my_array[0].age = 29;
// my_array[1].age = 3;
// my_array[2].age = 35;
// my_array[3].age = 4;
// After a sort that returns an array containing index values
// Note that the original array is unchanged.
// You can then use the returned array to display sorted information
// without modifying the original array.
var indexArray:Array = my_array.sortOn("age", Array.RETURNINDEXEDARRAY);
// my_array[0].age = 29;
// my_array[1].age = 3;
