AS3：使用外部SWF中的按钮

Question

I am making a website in Adobe Flash that imports it´s navigation buttons from an external swf-file. The problem is how my Main FLA-file will know which of the navigation buttons the users has pressed, since the buttons and it's eventListeners are in the external swf-file.

With other word: can I make my external swf-file return a Number to my website FLA-file, to determine which button that have been pressed? If so, how?

Answer 1

You can set up a connection between the external swf and main swf using the LocalConnection()

In main.swf

var sending_lc:LocalConnection;
sending_lc = new LocalConnection();

function send_it(evt:MouseEvent):void 
{
    sending_lc.send("connectionName", "functionName", "myData");
    //params are (connection name, function to execute in the receiving swf, the data to pass through)
}

my_btn.addEventListener(MouseEvent.MOUSE_UP, send_it);

In exetrnal.swf

var receiving_lc:LocalConnection;
receiving_lc = new LocalConnection();

receiving_lc.connect("connectionName");
receiving_lc.client = this;

function functionName(data:String):void {
trace(data);
}
