Question

我想问，
1如何将焦点放在AS3中的TextField中。在AS2中我通常使用

Selection.setFocus("<name of textfield instance>");
fscommand("activateTextField");

2.如何在AS3中复制动画片段。在AS2我正在使用

 <name of movie clip>.duplicateMovieClip();

由于

这是两个单独的问题，这两个问题都可以在线解答：

使用stage.focus将焦点设置在任何显示对象上：
```
stage.focus = name_of_textfield;
```

没有直接等同于duplicateMovieClip，但您可以通过从原始显示对象类创建new实例并复制原始属性来执行approximately the same thing： / p>

function duplicateDisplayObject(target:DisplayObject):DisplayObject {
    var targetClass:Class = Object(target).constructor;
    var duplicate:DisplayObject = new targetClass() as DisplayObject;

    // duplicate properties
    duplicate.transform = target.transform;
    duplicate.filters = target.filters;
    duplicate.cacheAsBitmap = target.cacheAsBitmap;
    duplicate.opaqueBackground = target.opaqueBackground;
    if (target.scale9Grid)
        duplicate.scale9Grid = target.scale9Grid;
    if (target.parent)
        target.parent.addChild(duplicate);
    if (target.hasOwnProperty("graphics") && target["graphics"] is Graphics)
        Graphics(duplicate["graphics"]).copyFrom(Graphics(target["graphics"]));

    return duplicate;
}

duplicateDisplayObject(name_of_movieclip);
