You have it, just decrease the i after any splice.
function removeArrayDuplicates ( array:Array )
{
var a:Array = [].concat ( array );
a.sort();
for ( var i = 0; i < a.length; i++ )
{
if ( a[ i ] == a[ i + 1 ] ) a.splice ( --i + 1, 1 );
}
return a;
}
var array = [ 'a', 'a', 'b', 'c', 'a', 'b', 'b', 1, 5, 1, 2, 3, 1, 'AA',
'AA' ];
trace( 'array before: ' + array );
var arrayAFTER = removeArrayDuplicates ( array );
trace( 'array after: ' + arrayAFTER );

Subject: [Flashcoders] remove duplicate items in array
hi guys
i'm looking for a way of removing duplicate items in an array
i've done this so far
//sort array so all items of the same content are grouped together
myArray.sort();
//loop through items, removing any sitting next to a duplicate
for (var i:Number = 0; i < myArray.length; i++) {
if (myArray[i] == myArray[i+1]) {
myArray.splice (i, 1);
}
}
however, i always seems to end up with the first 2 items in the array
being the same (although it works well after that)
i can't figure out why - hope you can help
obie
