<script language="JavaScript">
ZeroClipboard.setMoviePath( '/js/zero/ZeroClipboard.swf' );  //和copy.php不在同一目录需设置setMoviePath
ZeroClipboard.setMoviePath( '/js/zero/ZeroClipboard10.swf' );
var clip = new ZeroClipboard.Client();   //创建新的Zero Clipboard对象
clip.setText( '' ); // will be set later on mouseDown   //清空剪贴板
