JavaScript 实现通话计时（时分秒 本示例在uniapp中）
很简单，不做过多解释了，直接上代码
完整代码
<script>data() {return {startTime: 0,intervalId: null,}}methods: {startCall() {this.startTime = Date.now();this.intervalId = setInterval(() => {this.updateDuration();}, 1000);},updateDuration() {let elapsed = Date.now() - this.startTime; // 已经过的毫秒数let hours = Math.floor(elapsed / 3600000);let minutes = Math.floor((elapsed % 3600000) / 60000);let seconds = Math.floor((elapsed % 60000) / 1000);// 补零操作hours = hours < 10 ? '0' + hours : hours;minutes = minutes < 10 ? '0' + minutes : minutes;seconds = seconds < 10 ? '0' + seconds : seconds;this.dialTimeText = hours + ':' + minutes + ':' + seconds;},endCall() {clearInterval(this.intervalId);}}
</script>
