Key 679

Example

The following example calls the

getAscii() method any time a key is pressed. The example

creates a listener object named

keyListener and defines a function that responds to the

onKeyDown event by calling Key.getAscii().The keyListener object is then registered to

the

Key object, which broadcasts the onKeyDown message whenever a key is pressed while the

SWF file plays.

var keyListener:Object = new Object();

keyListener.onKeyDown = function() {

trace("The ASCII code for the last key typed is: "+Key.getAscii());

};

Key.addListener(keyListener);

When you use this example, be sure to select Control > Disable Keyboard Shortcuts in the test

environment.

The following example adds a call to

Key.getAscii() to show how the two methods differ.

The main difference is that

Key.getAscii() differentiates between uppercase and lowercase

letters, and

Key.getCode() does not.

var keyListener:Object = new Object();

keyListener.onKeyDown = function() {

trace("For the last key typed:");

trace("\tThe Key code is: "+Key.getCode());

trace("\tThe ASCII value is: "+Key.getAscii());

trace("");

};

Key.addListener(keyListener);
