        Flex4可以通过KeyboardEvent来获取键盘输入的值,例:

          <fx:Script>
                <![CDATA[
                        import mx.controls.Alert;
                       
                    public function getCode():void
                    {
                       btn.addEventListener(KeyboardEvent.KEY_DOWN,keyHandle);       
                    }
                    public function keyHandle(event:KeyboardEvent):void
                    {
                       Alert.show(“你按下了:” + String.fromCharCode(event.charCode));
                    }
                ]]>
        </fx:Script>
        <s:Button id=”btn”  click=”getCode()”/>

   当点击再进行按键时,就可以进行键的接收。
