JavaScript设定间隔自动获取下一个日期

最近在写一个自动排班功能,要求超过某设定的时间点后,自动计入下一个周期。以下为核心JS代码:

说明:

  • 本例中设置的超时时间点为每周五17:20;
  • 本例中设置的间隔周期为7天
  • 本例返回的格式为JS中的date类型(非格式化String)
//Get next date(liangxin 2020-09-11)
//Out JS date format
function getNextDate(){
	var now = new Date();
	var year = now.getFullYear();
	var date= now.getDate();
	var month = now.getMonth();
    var day = now.getDay();
    var hour = now.getHours();
    var minute = now.getMinutes();
    if(day == 5 && hour == 15 && minute >20 ){
       	var  nextDate =  AddDays(getDate(year+"-"+month+"-"+date+" 00:00:00"),7)+" 17:00:00" ;
       	return getDate(nextDate);
     }else{
    	 return getDate(year+"-"+month+"-"+date+" 17:00:00");
      }
	}

//Date add days
function AddDays(date,days){
	var nd = new Date(date);
	  nd = nd.valueOf();
	  nd = nd + days * 24 * 60 * 60 * 1000;
	  nd = new Date(nd);
	var y = nd.getFullYear();
	var m = nd.getMonth();
	var d = nd.getDate();
	if(m <= 9) m = "0"+m;
	if(d <= 9) d = "0"+d; 
	var cdate = y+"-"+m+"-"+d;
	return cdate;
	}


//String to date foramt 
function getDate(strDate) { 
	  var st = strDate; 
	  var a = st.split(" "); 
	  var b = a[0].split("-"); 
	  var c = a[1].split(":"); 
	  var date = new Date(b[0], b[1], b[2], c[0], c[1], c[2]);
	  return date; 
	} 

//格式化输出 JSON
console.log(getNextDate());
