vue实现发送短信倒计时和重发短信功能的示例详解

        <el-button @click="queryBtn()" type="primary">发送短信（{{countDown}}）</el-button>
        <el-button @click="resetBtn()" type="danger" :disabled="resetBtndisab">重发</el-button>

export default {
    data(){
        return {
            countDown:60, // 默认时间60秒
            countDownTimeout:null,  // 倒计时计数器
            resetBtndisab:true, //重发按钮初始值为不可用
        }
    },
    methods:{
            // 查询按钮
            queryBtn(){
                 this.doCountDown()
            },
            // 重置按钮
            resetBtn(){
                 this.$message({
                        message: '短信验证码已发送，请注意查收！',
                        type: 'success'
                 });
                 this.resetCountDown();
                 this.resetBtndisab=true
            },
            // 倒计时开始
            doCountDown(){
                this.countDownTimeout=setTimeout(()=>{
                    this.countDown--;
                    if(this.countDown<=0){
                            this.resetBtndisab=false
                    }else{
                        this.doCountDown(this.countDown)
                    }
                },1000)
		    },
            // 重置倒计时
            resetCountDown(){
                clearTimeout(this.countDownTimeout);
                this.countDown=60;
            }

    }
