vue-data-loading

vue-data-loading

Another component: infinite scroll and pull down to fetch data.

Here is a demo of HackNews

Install

npm install vue-data-loading --save

Usage

Import first:

import VueDataLoading from 'vue-data-loading'

The only you need to do is wrapping your data with vue-data-loading tag.

<vue-data-loading>
    <ul>
        <li v-for="(item, index) in list" :key="index">Item: {{item}}</li>
    </ul>
</vue-data-loading>

However, you can pass some props or events to the component.

<vue-data-loading :loading="loading" :listens="['pull-down', 'infinite-scroll']" @infinite-scroll="infiniteScroll" @pull-down="pullDown">
    <!--your data here-->
</vue-data-loading>

And sometimes, you may want to change the default slot:

Here is a example for infinite-scroll slot:

default:

<div class="d-table">
    <div class="d-cell infinite-scroll-loading">加载中...</div>
</div>

edit:

<div slot="infinite-scroll-loading" class="some-style-you-like">loading...</div>

Here is a example for handing event:

data() {
    return {
        list: [],
        loading: false,
    }
},
methods: {
    fetchData() {
        this.loading = true
        setTimeout(() => {
            const temp = [];
            for (let i = this.list.length + 1; i <= this.list.length + 50; i++) {
                temp.push(i);
            }
            this.list = this.list.concat(temp);

            this.loading = false
        }, 1000)
    },
    pullDown() {
        console.log('pull-down...')
        this.list = []
        this.fetchData()
    },
    infiniteScroll() {
        console.log('infinite-scroll...')
        this.fetchData()
    },
},
