我這里用的是vant-ui 如果用其他UI的小伙伴請修改template中的按鈕結(jié)構(gòu)
<template>
<div>
<van-button slot="button" size="small" type="danger" v-show="show" @click="getCode">發(fā)送驗證碼</van-button>
<van-button slot="button" size="small" type="danger" v-show="!show" >{{count}} s</van-button>
</div>
</template>
<script>
export default {
data() {
return {
show: true,
count: '',
timer: null
}
},
methods:{
getCode(){
const TIME_COUNT = 60;
if (!this.timer) {
this.count = TIME_COUNT;
this.show = false;
this.timer = setInterval(() => {
if (this.count > 0 && this.count <= TIME_COUNT) {
this.count--;
} else {
this.show = true;
clearInterval(this.timer);
this.timer = null;
}
}, 1000)
}
}
}
}
</script>
