推荐答案

问题是，你的应用程序中TextInput获得了焦点，但在HTML页面中您的Flex应用程序没有。所以基本上你需要的唯一额外的步骤就是给Flex应用程序的焦点。只有一个方法来实现这一目标：通过JavaScript。你应该这样做的在应用程序加载。

The issue is that within your application the TextInput has focus, but within the HTML page your Flex application does not. So basically the only extra step you need is to give the Flex app focus. There's only one way to achieve this: through JavaScript. And you should do it after the application was loaded.
