ckeditor粘贴事件对象不包含粘贴的数据

ckeditor粘贴事件对象不包含根据API文档应包含的属性：

我正在获取粘贴事件，如下所示：

CKEDITOR.on('instanceReady', function(ev) {
    alert('Pasted: ' + JSON.stringify(evt));
});

警报将返回以下字符串化对象：

{"name":"paste","sender":{"$":{"form_select_standardlanguage": 
{"0":{},"1":{"0":{},"1":{},"2":{},"3":{},"4":{},"5":{},"6":{}},"2":
{"0":{},"1":{}}},"location":{"href":"http://somehost.com
/somefile.php","origin":"http: 
//somehost.com","protocol":"http:","host":"somehost.com", 
"hostname":"somehost.com","port":"","pathname":   
"/somefile.php","search":"?searchkey=somekey","hash":""},
"data-cke-expando":102}},"data":{"$":{"isTrusted":true}}}

---

我需要的是粘贴的文本来检查它并对其进行更改。

您没有处理
