<view class='out' style='margin-top:10px'>
 <view class='in' style='width:{{progressWidth}}%'></view>
</view>
<view class='caozuo'>
 <text>{{progressTime}}秒</text>
 <text bindtap='playbtn' data-change='1'>{{playPausetips}}</text>
</view>

CSS:


.out {margin-left:auto;margin-right:auto;width:250px;height:20px;border:1px solid red;border-radius:20px;overflow:hidden;}
.in {height:100%;background-color:red;}
.caozuo{font-size:14px;color:#333;margin-left:auto;margin-right:auto;width:250px;margin-top:10px;display: flex;justify-content:space-between}

JS:


Page({
 data: {
 progressWidth:0,
 progressTime:60,
 mark:true,
 playPausetips:"开始"
 },
 playbtn() {
 let that = this;
 let mark = that.data.mark;
 if (mark){
 that.timer = setInterval(that.run, 1000); //that.timer关键点
 wx.showToast({
 title: '开始',
 })
 that.setData({
 mark:false,
 playPausetips:"暂停"
 })
 }else{
 clearInterval(that.timer);
 wx.showToast({
 title: '暂停',
 })
 that.setData({
 mark: true,
 playPausetips: "开始"
 })
 }
 },
 run(){
 let that = this;
 let totalProgressTime = 60 //秒
 let progressWidth = that.data.progressWidth; //显示进度
 let progressTime = that.data.progressTime; //时间
 
 if (progressWidth === 100) {
 wx.showToast({
 title: '结束回调处理',
 })
 clearInterval(that.timer);
 that.setData({
 progressTime: totalProgressTime, //进度条需要总时间s
 progressWidth: 100, //进度100%
 progressTime: 60
 })
 return;
 }
 progressTime--;
 progressWidth = (totalProgressTime - progressTime) * (100 / 60)
 that.setData({
 progressWidth: progressWidth,
 progressTime: progressTime
 })
 }
 
})
