JavaScript 获取当前日期和三十天以前日期

      function getThirtyDays() {
      //获取当前日期
     	  var myDate = new Date();
      var nowY = myDate.getFullYear();
      var nowM = myDate.getMonth()+1;
      var nowD = myDate.getDate();
      var enddateStr = nowY+"-"+(nowM<10 ? "0" + nowM : nowM)+"-"+(nowD<10 ? "0"+ nowD : nowD);//当前日期
     		var enddate = new Date(enddateStr);
      //获取三十天前日期
      var lw = new Date(myDate - 1000 * 60 * 60 * 24 * 30);//最后一个数字30可改，30天的意思
      var lastY = lw.getFullYear();
      var lastM = lw.getMonth()+1;
      var lastD = lw.getDate();
      var startdateStr =lastY+"-"+(lastM<10 ? "0" + lastM : lastM)+"-"+(lastD<10 ? "0"+ lastD : lastD);//三十天之前日期
     		var startDate = new Date(startdateStr);
     		const dateList = []
     		while(true) {
      			startDate.setDate(startDate.getDate() + 1)
     			if (startDate.getTime() <= enddate.getTime()) {
      if (startDate.getDate() < 10) {
      // startDate.getFullYear() 获取年，此处没加上年份
       dateList.push((startDate.getMonth()+1) + '.0' + startDate.getDate())
       } else {
       dateList.push((startDate.getMonth()+1) + '.' + startDate.getDate())
       }
      			} else {
      break
      			}
      		}
     		return dateList;
         }
