onKeyUp (Button.onKeyUp handler)

onKeyUp = function() {}

Invoked when a button has input focus and a key is released. The onKeyUp event handler is invoked with no parameters. You can use the Key.getAscii() and Key.getCode() methods to determine which key was pressed.

Availability: ActionScript 1.0; Flash Player 6

Example

In the following example, a function that sends text to the Output panel is defined for the onKeyDown handler. Create a button called my_btn on the Stage, and enter the following ActionScript in a frame on the Timeline:

my_btn.onKeyDown = function() {
    trace("onKeyDown: "+this._name+" (Key: "+getKeyPressed()+")");
};
my_btn.onKeyUp = function() {
    trace("onKeyUp: "+this._name+" (Key: "+getKeyPressed()+")");
};
function getKeyPressed():String {
    var theKey:String;
    switch (Key.getAscii()) {
    case Key.BACKSPACE :
        theKey = "BACKSPACE";
        break;
    case Key.SPACE :
        theKey = "SPACE";
        break;
    default :
        theKey = chr(Key.getAscii());
    }
    return theKey;
}

Press Control+Enter to test the SWF file. Make sure you select Control > Disable Keyboard Shortcuts in the test environment. Then press the Tab key until the button has focus (a yellow rectangle appears around the my_btn instance) and start pressing keys on your keyboard. When you press keys, they are displayed in the Output panel.
