[flexcoders] Re: Looping Through A DataProvider In Flex 2.0

Tue, 02 May 2006 11:00:47 -0700

What about this:

searchDP(FontFamily.dataProvider, "label", style.fontFamily);


public function searchDP(arrToSearch:ArrayCollection, field:String, value:String):Number
{  
 for (var idx = 0; idx < arrToSearch.length; ++idx)
 {     
  if (arrToSearch.getItemAt(idx)[field] == value) {return idx};
 }
 return -1;
}
