DataProvider.sortItemsBy() 329
■ Array.UNIQUESORT—if two objects in the array are identical or have identical sort fields,
this method returns an error code (0) instead of a sorted array.
■ Array.RETURNINDEXEDARRAY—returns an integer index array that is the result of the sort.
For example, the following array would return the second line of code and the array would
remain unchanged:
["a", "d", "c", "b"]
[0, 3, 2, 1]
You can combine these options into one value. For example, the following code combines
options 3 and 1:
array.sort (Array.NUMERIC | Array.DESCENDING)
Returns
Nothing.
Description
Method; sorts the items in the data provider in the specified order, using the specified field
name. If the
fieldName items are a combination of text strings and integers, the integer items
are listed first. The
fieldName parameter is usually "label" or "data", but advanced
programmers may specify any primitive value.
This method triggers the
modelChanged event with the event name sort.
This is the fastest way to sort data in a component. It also maintains the component’s
selection state. The
sortItemsBy() method is fast because it doesn’t run any ActionScript
while sorting. The
sortItems() method needs to run an ActionScript compare function, and
is therefore slower.
Example
The following code sorts the items in a list in ascending order using the labels of the list items:
myDP.sortItemsBy("label", "ASC");
