js判斷時間是否在某一時間段內

js判斷當前“時 : 分”是否在一天中某一區間內。
比如：15.30 在不在08.30到16.00之間。

 

 

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("休息吃飯時間");
} else {
alert("娛樂");
}
