js判断时间是否在某一时间段内

js判断当前“时 : 分”是否在一天中某一区间内。 比如：15.30 在不在08.30到16.00之间。

function checkAuditTime(beginTime, endTime) {
          
   
		var nowDate = new Date();
		var beginDate = new Date(nowDate);
		var endDate = new Date(nowDate);
		
		var beginIndex = beginTime.lastIndexOf(":");
		var beginHour = beginTime.substring(0, beginIndex);
		var beginMinue = beginTime.substring(beginIndex + 1, beginTime.length);
		beginDate.setHours(beginHour, beginMinue, 0, 0);
		
		var endIndex = endTime.lastIndexOf(":");
		var endHour = endTime.substring(0, endIndex);
		var endMinue = endTime.substring(endIndex + 1, endTime.length);
		endDate.setHours(endHour, endMinue, 0, 0);
		return nowDate.getTime() - beginDate.getTime() >= 0 && nowDate.getTime() <= endDate.getTime();
}

checkAuditTime("8:30", "16:00")；

例子：

if (checkAuditTime("12:00", "13:00") || checkAuditTime("17:30", "19:30")) {
          
   
		alert("休息吃饭时间");
} else {
          
   
		alert("娱乐");
}
