flash as3 - how do I find an object's index in an array

how do you find an object's index / position within an array in flash actionscript 3? I am trying to set a conditional up 开发者_运维百科in a loop where, if an object's id is equal to the current_item variable, I can return its position within the array.

Something like this might help you - this example returns the position of the value 7:

private var _testArray:Array = new Array(5, 6, 7, 8, 9, 8, 7, 6);

        public function ArrayTest() 
        {   
            trace (_testArray.indexOf(7));
            //Should output 2
        }

so for your needs:

 item variableToLookFor = 9 // Your variable here

 private var _testArray:Array = new Array(5, 6, 7, 8, 9, 8, 7, 6);

        public function ArrayTest() 
        {
            trace (_testArray.indexOf(variableToLookFor));
            //Should output 4
        }

This will return a -1 if your item doesn't exist, otherwise it will output the position in the array.
