如何使用FLASH组件实现下拉条功能（1）（AS3）

下拉条是制作FLASH课件时经常会用到的组件，但是对于不怎么会代码的同学，制作这样的效果就比较难了。在这里讲使用TextArea组件实现文字内容下拉条的方法。

打开制作软件，新建AS3文档。

打开组件面板，快捷键（Ctrl+F7）。

找到TextArea组件，用鼠标拖到舞台上，并用任意变形工具进行变形，改变大小。

选择这个组件，在属性面板中点击显示参数按钮打开参数面板。

在属性面板设置该组件的实例名为text_area，最后在主时间轴加如下代码：

text_area.text="asdfasdfasdfasdfasdfasdf\nasdfasdfasdfasdfasdfasdf\nasdfasdfasdfasdfasdfasdf\nasdfasdfasdfaasdfasdfasdfasdfasdfasdf\nasdfasdfasdfasdfasdfasdf\nasdfasdfasdfasdfasdfasdf\nasdfasdfasdfasdfasdfasdf\nasdfasdfasdfasdfasdfasdf\nasdfasdfasdfasdfasdfasdf\nasdfasdfasdfasdfasdfasdf\nasdfasdfasdfasdfasdfasdf\nasdfasdfasdfasdfasdfasdf\nasdfasdfasdfasdfasdfasdf\nasdfasdfasdfasdfasdfasdf\nsdfasdfasdf\nasdfasdfasdfasdfasdfasdf\nasdfasdfasdfasdfasdfasdf\nasdfasdfasdfasdfasdfasdf\nasdfasdfasdfasdfasdfasdf\nasdfasdfasdfasdfasdfasdf\nasdfasdfasdfasdfasdfasdf\nasdfasdfasdfasdfasdfasdf\nasdfasdfasdfasdfasdfasdf\nasdfasdfasdfasdfasdfasdf\nasdfasdfasdfasdfasdfasdf\nasdfasdfasdfasdfasdfasdf\nasdfasdfasdfasdfasdfasdf\n";

上面的代码中，\n是代表回车，要注意一下。

好了，简单的下拉条效果就出来了。
