time }}</div> <a-button style="margin-right: 20px" type="primary" @click="start" >开始</a-button > <a-button style="margin-right: 20px" type="primary" @click="reset" >重置</a-button > <a-button type="primary" @click="end">暂停</a-button> </div> </template> <script> export default {
data() {
return {
flag: null, hour: 0, minute: 0, second: 0, time: "00:00:00", }; }, methods: {
//开始计时 start() {
this.flag = setInterval(() => {
this.second = this.second + 1; if (this.second >= 60) {
this.second = 0; this.minute = this.minute + 1; } if (this.minute >= 60) {
this.minute = 0; this.hour = this.hour + 1; } this.time = this.complZero(this.hour) + ":" + this.complZero(this.minute) + ":" + this.complZero(this.second); }, 1000); }, //重新计时 reset() {
window.clearInterval(this.flag); this.hour = 0; this.minute = 0; this.second = 0; this.time = "00:00:00"; }, //暂停计时 end() {
this.flag = clearInterval(this.flag); }, //补零 complZero(n) {
return n < 10 ? "0" + n : "" + n; }, }, }; </script> <style> .timeContainer {
font-size: 40px; margin-bottom: 10px; } </style> 讯享网
