Remove movieClips using array list? - arrays

Question

I've a array of list and created image place holder with the array objects name (Example: myArray[a,b]) and loaded images from there, having array list as folder name.
And finally created a movieClip to load on them and display in stage.
Now I want to remove them calling the same array list.
Need help here...
My code below:
for (var l: int = 0; l < ListArray.length; l++) {
var BookName: MovieClip = new bookThumb();
trace("\n[" + l + "]: " + ListArray[l]);
ImageFoldername = ListArray[l];
var bookImagePath: String = "file://" + File.userDirectory.nativePath.toString() + "/Books/" + ImageFoldername + "/Images/Icon.png";
trace(bookImagePath);
var ImagePlacer: Loader = new Loader;
var ImageURL: URLRequest = new URLRequest(bookImagePath);
ImagePlacer.load(ImageURL);
BookName.addChild(ImagePlacer);
BookName.name = ImageFoldername
addChild(BookName)
BookName.x = FirstBook_x;
BookName.y = FirstBook_y;
BookName.buttonMode = true;
BookName.mouseChildren = false;
BookName.addEventListener(MouseEvent.CLICK, IconSelected);
BookName.alpha = .8
BookName.addEventListener(MouseEvent.MOUSE_OVER, IconMouseOver);
BookName.addEventListener(MouseEvent.MOUSE_OUT, IconMouseOut);
FirstBook_x = FirstBook_x + 250;
}

Because you assign the ImageFoldername to each MovieClip's name property, you can use getChildByName to find them and remove them:
(Note: convention in AS3 is to use UpperCamelCase for classes, and lowerCamelCase for variables and functions. I've written the code below following this convention. )
for (var i:int = 0; i < listArray.length; i++) {
var imageFolderName:String = listArray[i];
var bookThumb:BookThumb = getChildByName(imageFolderName) as BookThumb;
if (bookThumb) {
removeChild(bookThumb);
}
}
Another way you can handle it is to add each book thumb into a list:
var bookThumbs:Array = [];
for (var i:int = 0; i < listArray.length; i++) {
var bookThumb:Bookthumb = new BookThumb();
bookThumbs.push(bookThumb);
// ...
}
Then to remove them all:
for each (var bookThumb:BookThumb in bookThumbs) {
removeChild(bookThumb);
}
bookThumbs.length = 0;
But probably the easiest way to remove them all would be to simply put them all in a single container and later use removeChildren() to remove them all:
var container:Sprite = new Sprite();
addChild(container);
for (var i:int = 0; i < listArray.length; i++) {
var bookThumb:Bookthumb = new BookThumb();
container.push(bookThumb);
// ...
}
// when you want to remove them all:
container.removeChildren();
