单击datepicker时无法选择时间

Question

我有两个输入框，一个用于选择日期，另一个用于选择时间，我试图根据某些条件验证这两个框，这样如果没有选择日期，时间不应该被选中，我是使用eonasdan datetimepicker，我得到了所需的输出，但没有单击时间戳可以帮助我解决这个问题

以下是我到目前为止所做的事情：

function starttime(){
            $('#starttime').datetimepicker({
                  format: 'HH:mm',
                  minDate: new Date()
                });
           }
           
           $('.start_time_addon').on('click keyup',function(){
            var x = $('#start').val();
           if (x == '') {

            alert('please select startdate first');
            return false;
           
           }
           else{

            starttime();
            
           }
          
        });
        
        var datePickerSix= $('.datetimepicker6');
          $(datePickerSix).datetimepicker({
          format: 'DD/MM/YYYY',
          
minDate: new Date()
        });

 $('.datetimepicker6').datetimepicker({
          format: 'DD/MM/YYYY',
          
minDate: new Date()

        });
       $('.datetimepicker6').on("dp.change", function(e) {
            $('#starttime').datetimepicker({
            
                  format: 'HH:mm',
                  minDate: new Date()
                });

});
