Thanks Francis, Tom Bray also straightened me out on that.
I was wrong, and I feel properly
chastened. Thank you for the help! From:
[email protected] [mailto:[EMAIL PROTECTED] On Behalf Of Francis Cheng Don’t forget that the Array.sort() method sorts using string
values by default, so even when sorting an array of numbers or ints, they will
be sorted as if they were strings. To get numeric sorting, so that
“10” comes after “2”, use the Array.NUMERIC sort
option, e.g.: myArray.sort(Array.NUMERIC); Here’s the relevant example from the ActionScript
documentation for Array.sort(): The following code
creates the Array object numbers with
elements [3,5,100,34,10]. A call to sort()
without any parameters sorts alphabetically, producing the undesired result [10,100,3,34,5].
To properly sort numeric values, you must pass the constant NUMERIC
to the sort() method, which sorts numbers
as follows: [3,5,10,34,100]. Note:
The default behavior of the sort()
function is to handle each entity as a string. The Array.NUMERIC
argument does not actually convert other data types to the Number data type; it
simply allows the sort algorithm to recognize numbers. var
numbers:Array = new Array(3,5,100,34,10); trace(numbers);
// 3,5,100,34,10 numbers.sort(); trace(numbers);
// 10,100,3,34,5 numbers.sort(Array.NUMERIC); trace(numbers);
// 3,5,10,34,100 Francis From: Thanks Tom, I believe array indices are ints, not strings. However, I also
believe that datagrid indices are strings, because when I used the Array.sort()
function on the DataGrid.selectedIndices array, the order was all messed up.
For example, “10” came before “2”. For that reason, I
ended up writing a custom sort function to get around the issue. Thanks again! Jim From: Try either
of these two options: On 6/8/06, Jim Robson <[EMAIL PROTECTED]> wrote: I don't understand why DataGrid.selectedIndices
returns an array of Strings. I thought that indices were generally integers.
(For example, Array.indexOf returns an int.) Can anyone explain why the selected index of a
DataGrid is a String? When "dgTest" is a DataGrid instance, the following
code generates a compiler error: var arr:Array = dgTest.selectedIndices; for(var i:int in arr){ // do something } The error that the compiler returns is as follows: "Implicit coercion of a value of type String to
an unrelated type int. " -- Flexcoders Mailing List FAQ: http://groups.yahoo.com/group/flexcoders/files/flexcodersFAQ.txt Search Archives: http://www.mail-archive.com/flexcoders%40yahoogroups.com
