actionscript-3 - 以编程方式将类与文档关联

Question

当按下按钮时，我想将我的类与文档相关联。我怎样才能以编程方式做到这一点？到目前为止，我已经尝试过这种方法：如何以编程方式将 flash .fla 文件与文档类关联？编译器告诉我没有名为 getDocumentDOM() 的函数。我还应该尝试什么？

The document class is fixed, but you can easily instantiate new classes and add or remove them on the main timeline.

As someone commented, this is a design problem. Instead of using frames on the main timeline, select the content of your first frame and convert it into a library symbol and export it for ActionScript with a class name like "StartScreen".

You can then have the constructor of your main document class call var start_screen:StartScreen = new StartScreen(); addChild( start_screen ); to instantiate it on the main timeline. You'll have to attach an event listener to the button, such as start_screen.start_button.addEventListener( MouseEvent.CLICK, handler, false, 0, true );. Your handler function can then call removeChild( start_screen ); and add some other content in its place.
