One Function, multiple buttons

Question

I am new to AS3 and AS in general.  I know enough that you have to add event listener and create a function to handle when a button is clicked. If I have 4 buttons that I want links to 4 different pages, do I have to have 4 functions?  One for each button?  Or is there a way to use one function and somehow catch a value that determines which button was clicked and then open the corresponding URL?
I know this has to be simple, I just don't know the answer.  Thanks for the help!

Answer 1

You can use 1 function to handle all 4 button's clicks. See the example code I provided. To make the code work just drag the AS3 button component onto your movie and delete it from the stage; this will add the Button to the FLA library and make it accessible for use in code. I also attached a FLA of this example to this post.
Let me know if you have any trouble.
Good luck.
