vue3写一个定时器
vue3没有this，取而代之的是proxy
所以在定时器的写法上也有所不同
话不多说直接上代码
<template>
<p>剩余时间:{{ count }}</p>
</template>
export default{
const seconds = ref(1800);//定义一下秒数，根据秒数来计算，需要自己判断
const countDown = () => {
let d = parseInt(seconds.value / (24 * 60 * 60));
d = d < 10 ? "0" + d : d;
let h = parseInt((seconds.value / (60 * 60)) % 24);
h = h < 10 ? "0" + h : h;
let m = parseInt((seconds.value / 60) % 60);
m = m < 10 ? "0" + m : m;
let s = parseInt(seconds.value % 60);
s = s < 10 ? "0" + s : s;
count.value = m + "分" + s + "秒";
// console.log('监听',count.value );
};
//
const timed = () => {
dsq.value = setInterval(() => {
seconds.value -= 1;
countDown();
}, 1000);
};
}
这样下来，一个倒计时30分钟的定时器就写好了
