Chapter 6: ActionScript Core Classes
By default,
Array
.
sortOn()
works as described in the following list:
•
Sorting is case-sensitive (
Z
precedes
a
).
•
Sorting is ascending (
a
precedes
b
).
•
The array is modified to reflect the sort order; multiple elements that have identical sort fields
are placed consecutively in the sorted array in no particular order.
•
Numeric fields are sorted as if they were strings, so 100 precedes 99, because “1” is a lower
string value than “9”.
You can use the
option
flags to override these defaults. The following examples use different
forms of the
option
flag for illustration purposes. If you want to sort a simple array (for example,
an array with only one field), or if you want to specify a sort order that the
options
parameter
doesn’t support, use
Array.sort()
.
To pass multiple flags in numeric format, separate them with the bitwise OR (
|
) operator or add
the values of the flags together. The following code shows three ways to specify a numeric
descending sort:
my_array.sortOn(someFieldName, 2 | 16);
my_array.sortOn(someFieldName, 18);
my_array.sortOn(someFieldName, Array.DESCENDING | Array.NUMERIC);
Consider the following array:
var my_array:Array = new Array();
my_array.push({password: "Bob", age:29});
my_array.push({password: "abcd", age:3});
my_array.push({password: "barb", age:35});
my_array.push({password: "catchy", age:4});
Performing a default sort on the password field produces the following results:
my_array.sortOn("password");
// Bob
// abcd
// barb
// catchy
Performing a case-insensitive sort on the password field produces the following results:
my_array.sortOn("password", Array.CASEINSENSITIVE);
// abcd
// barb
// Bob
// catchy
Performing a case-insensitive, descending sort on the password field produces the following
results:
my_array.sortOn("password", 1|2);
// catchy
// Bob
// barb
// abcd
