添加事件監聽

 // 給需要添加監聽事件的對象添加參數
 //id, index, issubmited是已存在的值
 document.getElementById(id)._params = { id, index, issubmited };
 //_this.pasteFun函數為執行函數
 document.getElementById(id).addEventListener("paste", _this.pasteFun);

執行函數

pasteFun(event) {
      var { id, index, issubmited } = event.target._params;
      //.....
   }

移除

 document.getElementById(id).removeEventListener("paste", this.pasteFun);

over!
