[JavaScript知识库]vue项目:计时并格式化实现暂停功能

格式化调用moment.js,请自行安装到项目。

moment官网地址贴到这里:文档 | Moment.js 中文网

效果如下:样式自己调整

HTML部分:

<template>
	<view>
		<view>
			{{formatTime()}}
		</view>
		<button @click="swichType">{{buttonText}}</button>
	</view>
</template>

js:

<script>
	import moment from "moment"
	export default {
		data() {
			return {
				buttonText: '开始',
				icon: "play-circle-fill",
				buttonType: true, //true为开始， flase为结束
				realTime: 0,
				interval: '',
			}
		},
		onLoad() {

		},
		methods: {
			formatTime() {
				return moment(moment.duration(this.realTime, 'seconds') 
 ['_milliseconds']).utc().format('HH:mm:ss',)
			},
			timeIncrease() {
				this.interval = setInterval(_ => {
					this.realTime += 1;
				}, 1000)
			},
			swichType() {
				if (this.buttonType) {
					this.buttonText = "暂停"
					this.timeIncrease()
				} else {
					this.buttonText = "开始"
					clearInterval(this.interval)
				}
				this.buttonType = !this.buttonType
			},
		
		}
	}
</script>
