Better Way to Reference One of Many Objects

How do you guys reference one of multiple objects? Every recent project of mine winds up having a bunch of items pushed into an array, and I find out which one to manipulate like this:


function myFunction():void
{
   index = e.target.name.slice(5,7);       // object is named "item_1"
   myArray[index].x += 5 (or whatever);
}

Is there an “ideal” (or better) way to do this? I hope this makes sense.
