1. 定义全局变量
data() {
return {
textClose: ""m:'',// 格式化后的分
s:'',// 格式化后的秒
};
},2. 调用之前先革除定时器
let examMinute = 90; // 90 FENZHOGN
let tolTimers = examMinute * 60 * 1000;
let tolS = tolTimers;
const mm = Math.floor(tolTimers / 1000 / 60);
const ss = Math.floor((tolTimers / 1000) % 60);
that.m = mm > 9 ? mm : '0' + mm;
that.s = ss> 9 ? ss: '0' +ss;
// 革除定时器
that.textClose && clearInterval(that.textClose);
that.textClose = null;
that.textClose = window.setInterval(() => {if (tolS<= 1000) { // 倒计时
that.automaticSubmit = true;
window.clearInterval(that.textClose);
}else{
tolS-= 1000;
// console.log('tolS',tolS);
if(tolS<= 5* 60 * 1000){that.countDownFlag = true;}
const mm = parseInt((tolS / 1000 / 60))
const ss = parseInt(tolS / 1000 % 60)
that.m = mm > 9 ? mm : '0' + mm;
that.s =ss> 9 ? ss: '0' +ss;
}
}, 1000);
// 销毁定时器
that.$once('hook:beforeDestroy', ()=>{clearInterval(that.textClose);
})
