large-list's Introduction

Install

// npm
npm install large-list

// yarn
yarn add large-list

Usage

import LargeList from 'large-list';

Vue.component('LargeList', LargeList);

<LargeList>
    <PostCard>
    </PostCard>
</LargeList>

子组件需要提供heightChange事件，并且将新的高度newHeight，以及自身的id作为事件参数。

export default {
    name: 'PostCard',
    mounted() {
        this.$emit('heightChange', newHeight, id);
    },
}
