arraySort

Sorts array elements.

arraySort(array, sortType [, sortOrder [, localeSensitive ]]) or arraySort(array, callback) → returns boolean

Member Function Syntax

someArray.sort(sortType [, sortOrder, localeSensitive ])

Argument Reference

array array
Required

Name of an array

sortType string
Required

numeric: sorts numbers
text: sorts text alphabetically, taking case into account
(also known as case-sensitive). All letters of one case
precede the first letter of the other case:
- aabzABZ, if sort_order = "asc" (ascending sort)
- ZBAzbaa, if sort_order = "desc" (descending sort)

textnocase: sorts text alphabetically, without regard to
case (also known as case-insensitive). A letter in varying
cases precedes the next letter:
- aAaBbBzzZ, in an ascending sort; preserves original
intra-letter order
- ZzzBbBaAa, in a descending sort; reverses original
intra-letter order

Values:

numeric
text
textnocase

sortOrder string
Default: `asc`

asc: ascending sort order. Default.
- aabzABZ or aAaBbBzzZ, depending on value of sort_type,
for letters
- from smaller to larger, for numbers

desc: descending sort order.
- ZBAzbaa or ZzzBbBaAa, depending on value of sort_type,
for letters
- from larger to smaller, for numbers

Values:

asc
desc

callback function

CF 10+ A function that uses two elements of an array. function(element1, element2). Returns whether the first is less than (-1), equal to (0) or greater than (1) the second one (like the compare functions).

localeSensitive boolean
Default: `false`

CF 10+ Specify if you wish to do a locale sensitive sorting.

Compatibility

ColdFusion:

CF2018+ Member function returns the sorted array.

Examples
Sample code invoking the arraySort function

Simple example for arraySort function

Uses the arraySort() function to get the sorted array and which sorted by type numeric

someArray = [10,20,-99,46,50];
arraySort(someArray, "numeric", "desc");
writeOutput( serializeJSON(someArray) );

Expected Result: [50,46,20,10,-99]

Simple example with member function

CF 11+ Lucee 4.5+

someArray = ["COLDFUSION","coldfusion","adobe","LucEE","RAILO"];
someArray.sort("text","desc");
writeOutput( serializeJSON(someArray) );

Expected Result: ["coldfusion","adobe","RAILO","LucEE","COLDFUSION"]

Simple example with callback function

Uses the callback function

someArray = [
    {name="testemployee", age="32"},
    {name="employeetest", age="36"}
];
arraySort(
    someArray,
    function (e1, e2){
        return compare(e1.name, e2.name);
    }
);
writeOutput( serializeJSON(someArray) );

Expected Result: [{"NAME":"employeetest","AGE":"36"},{"NAME":"testemployee","AGE":"32"}]
