根据switch case值创建对象

Question

我有以下开关案例：

    switch (appModel.currentPage){
                case "Programma":
                case "Winkelwagen":
                case "Films":
                case "Contact":
                    if (page){
                        removeChild(page);
                    }
    //here i would like to create a new object page that has the type of the switch.
i mean this: var page: getDefinitionByName(appModel.currentPage+"Page");

this doesnt work thou but it should be something like: "FilmsPage or ContactPage or ...".
                    addChild(page);
                    break;

有谁知道怎么做？

Answer 1

var pageClass:Object = getDefinitionByName(appModel.currentPage+"Page");
var page:DisplayObject = new pageClass();
addChild( page );

Answer 2

PatrickS的答案应该有效，但是你需要确保你将使用的所有类都被引用，或者编译器会跳过它们，而不是将它们添加到你的SWF中。
