AS3.0 button event

Hi,

In this i like to specify a simple button example in AS3.0.
Most people says we cant wright code in frame That is FALSE...  We can... In this example i has written the code in the frame.

Step 1:
Create a button and place it in the stage... Give the instance name for it In my example i has specified as b1.

Step 2:
Go to the frame Now and add a event listener for that button.
 like

Syntax:
<button>.addEventListener(<eventname>, <function_name>);
in our example
b1.addEventListener(MouseEvent.CLICK, button_click);

Step 3:
Write the code for function

Syntax
function <function_name>(<event object>:<event>):<return type>
{
//code for the function
}

in our example
function button_click(event:MouseEvent):void
{
    trace("button is clicked");
}

where
button_click is the function Name
event is the object of the MouseEvent
MouseEvent is the event name.

You are done.
Run the file You made a button to work in AS3.0

Hear is the whole code...
function button_click(event:MouseEvent):void
{
    trace("button is clicked");
}

b1.addEventListener(MouseEvent.CLICK, button_click);
