Question

我有应用程序，其中有时间动态绑定，其中场景可能允许时间为空，

在Jquery中，datetimepicker设置允许时间null设置为此处显示的示例，该值应为null

如何设置空值时间？

＆＃13;

$(document).ready(function(){
  try{ $('.DATETIMEFIELD').datetimepicker({
      value:'', 
      datepicker:false, 
      format:'h:i A', 
      formatTime: 'h:i A', 
      step:30 ,
      allowTimes: [], 
   }); 
   }
   catch(e){
       console.log(e);
   };
});

<input type="text" class="DATETIMEFIELD">

如果array为null，则可以销毁日期时间选择器。在这两种情况下，您都可以在查询datetimepicker之前进行检查。

$(document).ready(function(){
var timedata1=[32, 33, 12, 40]
var timedata2=[]
  try{ 
  $('.DATETIMEFIELD').datetimepicker({
      value:'', 
      datepicker:false, 
      format:'h:i A', 
      formatTime: 'h:i A', 
      step:30 ,
      allowTimes:timedata1, 
   }); 
   
   if(timedata2.length==0 || timedata2==null){
      $(".DATETIMEFIELD1").datepicker("destroy");      
   }else{
    $('.DATETIMEFIELD1').datetimepicker({
      value:'', 
      datepicker:false, 
      format:'h:i A', 
      formatTime: 'h:i A', 
      step:30 ,
      allowTimes:timedata1, 
   }); 
   }
   }
   catch(e){
       console.log(e);
   };
});
