Lottie 动画

Lottie (opens new window) 是 Airbnb 开发的，一个适用于 Android、iOS、Web 和 Windows 的库，能够渲染 Adob​​e After Effects 动画特效。

wu-plus-lottie 是基于 lottie-web 重新进行了封装，开发者无需手动实例化 Lottie， 可如同普通 HTML 标签般接入。

基础用法

场景

很多场景中都可以使用组件，如空列表的数据。

<template>
    <div class="button-container" style="display: flex; flex-wrap: wrap; align-items: center;justify-content: space-around;padding: 16px">
        <div style="width: 300px; height: 300px">
            <wu-plus-lottie data="https://qiniu.canyuegongzi.xyz/com/empty-list.json"></wu-plus-lottie>
        </div>  
    </div>

动画控制——开始停止

可以通过 相关 Api 控制动画的开始停止，具体 Api 可参考 (opens new window)。

开始 动画中?true 停止

<template>
    <div class="itemContainer_12">
        <div class="item_12">
            <wu-plus-lottie data="https://qiniu.canyuegongzi.xyz/lf20_qynqmsel.json" :ref="onRef1"></wu-plus-lottie>
