kendo datepicker 与dropdownlist popup冲突解决

   dtpEL.kendoDateRangePicker({
       labels: false,
       calendarButton: true,
       "messages": {
           "startLabel": "",
           "endLabel": ""
       }
   });

  var datePicker = dtpEL.data("kendoDateRangePicker");
  ddl.bind('close', function (e) {
      if (datePicker.dateView.popup.visible()) e.preventDefault(); // prevent popup closing
  })

// 留痕
//datePicker.dateView.popup.options.appendTo = origin.data('kendoDropDownList').popup.options.appendTo;
//datePicker.dateView.popup.bind('close', function (e) {
//    debugger;
//    e.preventDefault(); //prevent popup closing
//})
//datePicker.dateView.div.on('click', function (event) {
//    debugger;
//    event.preventDefault();
//    event.stopPropagation();
//});
