在mounted中創(chuàng)建并執(zhí)行定時(shí)器翁脆，然后在beforeDestroy或者destroyed中清除定時(shí)器
<template>
<div class="about">
</div>
</template>
<script>
export default {
name: "about",
data() {
return {
//接收定時(shí)器
timer: ""
};
},
mounted() {
let _this = this;
let num = 0;
//創(chuàng)建并執(zhí)行定時(shí)器
this.timer = setInterval(() => {
//當(dāng)num等于100時(shí)清除定時(shí)器
if (num == 100) {
clearInterval(_this.timer);
}
console.log(num++);
}, 1000);
},
beforeDestroy() {
//清除定時(shí)器
clearInterval(this.timer);
console.log("beforeDestroy");
},
destroyed() {
//清除定時(shí)器
//clearInterval(this.timer);
console.log("destroyed");
}
};
</script>
<style scoped>
</style>
這樣在組件銷毀時(shí)會(huì)清除定時(shí)器，具體參考的是vue的生命周期函數(shù)凯正，詳情去官網(wǎng)查看哦
