AS打造的复制粘贴功能 (1)

主要代码：

//定义公共函数。。。
class ClipBoard extends Object {
static var $contents:Object;
static var $operation:String;
function ClipBoard() {
}
//定义当选择剪切时的效果。。。
public static function cut(obj) {
obj._alpha = 50;
$contents = obj;
$operation = "cut";
}
//定义复制函数。。。
public static function copy(obj) {
$contents = obj;
$operation = "copy";
}
//定义删除函数。。。
public static function remove(obj) {
$contents = obj;
$operation = "remove";
$contents.removeMovieClip();
}
//定义顺时针旋转。。。
public static function rotation(obj) {
$contents = obj;
$operation = "rotation";
$contents._rotation += 45;
}
//定义逆时针旋转。。。
public static function rotation2(obj) {
$contents = obj;
$operation = "rotation2";
$contents._rotation -= 45;
}
//定义移动。。。
private static var xm:Number;
private static var ym:Number;
public static function movethis(obj) {

$contents._y += (ym-$contents._y)/5;
if (Math.abs($contents._x-xm)<0.5) {
_root.onEnterFrame = undefined;
}
};
}
}
//定义刷新。。。
public static function refish() {
getURL("javascript:location.reload()");
}
//定义粘贴功能。。。
public static function paste() {
