actionscript-3 - Setting focus of input field in externally loaded swf

Question

I'm loading a swf form into my swf movie (to save on file size). I have a 'faux-form' of static MCs in the main swf, and when a user clicks one, it loads the 'real form' which is its own swf file. What I want to do is properly set the focus of the real form's input field, based on the MC of the faux form the user clicks.

For example: User watches animation and sees form on last frame (faux form). User clicks on the 'city' input field to enter their city. Externally loaded swf file with 'real form' is immediately loaded into the main swf on top of the faux form, so the user has active input fields to interact with. Text input field 'city' should now be in focus.

Thanks in advance for any help!

如果您有对要设置焦点的文本输入的引用，可以使用以下内容：

var cityInputField:TextField = mc.getChildByName("cityInputField") as TextField;
if(cityInputField)
   stage.focus = cityInputField;
