compareFunction
An optional comparison function used to determine the sorting order of elements in an array. Given the elements A and B, the orderfunc
parameter can have one of the following three values:
Nothing.
Method; sorts the array in place, without making a copy. If you omit the compareFunction
parameter, Flash sorts the elements in place using the <
comparison operator.
The following example uses Array.sort
without specifying the compareFunction
parameter:
var fruits_array = ["oranges", "apples", "strawberries", "pineapples", "cherries"];
trace(fruits_array.join());
fruits_array.sort();
trace(fruits_array.join());
Output:
oranges,apples,strawberries,pineapples,cherries
apples,cherries,oranges,pineapples,strawberries
The following example uses Array.sort
with a specified order function.
var passwords_array =[ "gary:foo", "mike:bar", "john:snafu", "steve:yuck", "daniel:1234" ]; function order (a,b){ //Entries to be sorted are in form name:password //Sort using only the name part of the entry as a key. var name1 =a.split(":")[0 ]; var name2 =b.split(":")[0 ]; if (name1 <name2){ return -1; }else if (name1 >name2){ return 1; }else { return 0; } } for (var i=0;i<passwords_array.length;i++){ trace (passwords_array.join()); } passwords_array.sort(order); trace ("Sorted:"); for (var i=0;i<passwords_array.length;i++){ trace (passwords_array.join()); }
Running the previous code displays the following result in the Output window.
daniel:1234
gary:foo
john:snafu
mike:bar
steve:yuck
