js秒數格式化

前端經常會從後端獲取到時間，比如我今天就碰到，後端只返回秒數，只能我自己轉義，就寫了個小方法，把3921轉化爲1小時5分鐘21秒這樣的格式，總的來說就是不斷遍歷自身的秒數。用起來非常的簡單！！！

 

var secdons = 3921
var timeFormat = ''

function timeFilter(secdons){
	if (secdons<60){
		var sec
		sec = (secdons>0)?secdons + '秒':''
		timeFormat = timeFormat + sec
		return;
	}
	else if(secdons<3600){
		var min
		min = Math.floor(secdons/60)
		//console.log(min)
		timeFormat = timeFormat + min + '分鐘'
		timeFilter(secdons-min*60)
	}
	else{
		var hour
		hour = Math.floor(secdons/3600)
		timeFormat = timeFormat + hour + '小時'
		timeFilter(secdons-hour*3600)
	}
}
timeFilter(secdons)
console.log(secdons)
console.log(timeFormat)
