<input id="copy" type="button" value="复制">
</body>
<script src="<?php echo Yii::app()->baseUrl;?>/resources/libs/js/ZeroClipboard/ZeroClipboard.js"></script>
<script language="JavaScript">
    var clip = new ZeroClipboard(document.getElementById(‘copy‘));
    clip.on({
        "ready": function(){ alert("加载完成!"); },
        "copy" : function(e){alert(‘copy‘);e.clipboardData.setData("text/plain", "这里是用于复制的纯文本数据");},
        "aftercopy": function (e) {alert(‘copy complete‘);}
    });

</script>
