How to remove child in an array in actionscript

How to remove a child in an array in ActionScript 3.0? Here's my code. I put the child I want to remove in an array called nailList[] and put it on gameStage.

function makeNails():void
{   
    for (var i=0; i< 3; i++)
    {
        for (var j=0; j<3; j++)
        {
            var tempNail = new Nail2(j * C.NAIL_DISTANCE + C.NAIL_START_X,
            i * C.NAIL_DISTANCE + C.NAIL_START_Y);

            nailList.push(tempNail);
            gameStage.addChild(tempNail);
        }
    }
    gameStage.addEventListener(Event.ENTER_FRAME,update);
    gameStage.addEventListener(MouseEvent.CLICK, clickToHit);
}

Here's the code I used to remove the nails. But nothing happens after this code. The nails are still there.

for (var j:int = nailList.length; j >= 0; j--)
{   
    removeNails(j);
    trace("Remove Nail");
}
function removeNails(idx:int)
{
    gameStage.removeChild(nailList[idx]);
    nailList.splice(idx,0);
}

I want to remove the MovieClip so that I can restart the game and add new ones.

Valid array index range is from 0 to length - 1. You are trying to call removeChild with nailList[nailList.length] which is invalid and removeChild should fire an error. You need to change the initial value of j to nailList.length - 1.

for (var j:int = nailList.length - 1; j >= 0; j--)
                                 ^^^

Another problem is (as pointed in the comment) the second parameter of splice is delete count. So you need to use 1 instead of 0.

nailList.splice(idx, 1);
                     ^

You can use splice to remove the child of an array.

arrName.splice(2,1);

Hope it will help.
