let audio = new Audio('./img/nihong.mp3');
let audioStatus = true
let times
$('#playButton').on('click', function() {
	if (audioStatus == true) {
		audio.play();
		daojishi()
		audioStatus = false
	} else {
		audio.currentTime = 0;
		audio.pause();

		$('#countdown').html('4:31');
		audioStatus = true
	}
	setTimeout(function() {
		audio.currentTime = 0;
		audio.pause();
		$('#countdown').html('4:31');
		audioStatus = true
	}, 271000)
})

function daojishi() {
	var m = 4;
	var s = 31;
	times = setInterval(function() {
		if (s < 10) {
			//如果秒数少于10在前面加上0
			$('#countdown').html(m + ':0' + s);
		} else {
			$('#countdown').html(m + ':' + s);
		}
		s--;
		if (s < 0) {
			//如果秒数少于0就变成59秒
			s = 59;
			m--;
		}
	}, 1000)
}
