PullRefresh 下拉刷新
引入
import Vue from 'vue';
import { PullRefresh } from 'vant';
Vue.use(PullRefresh);
代码演示
基础用法
下拉刷新时会触发 refresh 事件,在事件的回调函数中可以进行同步或异步操作,操作完成后将 v-model 设置为 false,表示加载完成。
<van-pull-refresh v-model="isLoading" @refresh="onRefresh">
<p>刷新次数: {{ count }}</p>
</van-pull-refresh>
import { Toast } from 'vant';
export default {
data() {
return {
count: 0,
isLoading: false
}
},
methods: {
onRefresh() {
setTimeout(() => {
Toast('刷新成功');
this.isLoading = false;
this.count++;
}, 1000);
}
}
}
成功提示
通过success-text可以设置刷新成功后的顶部提示文案
<van-pull-refresh
v-model="isLoading"
success-text="刷新成功"
@refresh="onRefresh"
>
<p>刷新次数: {{ count }}</p>
</van-pull-refresh>
自定义提示
通过插槽可以自定义下拉刷新过程中的提示内容
<van-pull-refresh v-model="isLoading" :head-height="80" @refresh="onRefresh">
<!-- 下拉提示,通过 scale 实现一个缩放效果 -->
<template #pulling="props">
<img
class="doge"
src="https://img.yzcdn.cn/vant/doge.png"
:style="{ transform: `scale(${props.distance / 80})` }"
/>
</template>
<!-- 释放提示 -->
<template #loosing>
<img
class="doge"
src="https://img.yzcdn.cn/vant/doge.png"
/>
</template>
<!-- 加载提示 -->
<template #loading>
<img
class="doge"
src="https://img.yzcdn.cn/vant/doge-fire.jpg"
/>
</template>
<p>刷新次数: {{ count }}</p>
</van-pull-refresh>
<style>
.doge {
width: 140px;
height: 72px;
margin-top: 8px;
border-radius: 4px;
}
</style>
