超好用的uniapp彈出層

 

 

 

 

 

 

要點： 

 1. 動態控制css。

<view class="share-item" :class="{'share-show': shareState}">

 

 2. css裏面設置優先級

// 進入分享動畫
.share-show {
    transition: all 0.3s ease;
    transform: translateY(0%) !important;
}
// 離開分享動畫
.share-item {
    position: fixed;
    left: 0;
    bottom: 0;
    width: 100%;
    height: auto;
    background-color: #FFFFFF;
    transition: all 0.3s ease;
    transform: translateY(100%);
    z-index: 1999;
}

 

下面是分享組件的全部代碼，share.vue文件。

<template>
    <view class="share">
        <view :class="{'share-box': shareState}" @click="handleHiddenShare">
        </view>
        <view class="share-item" :class="{'share-show': shareState}">
            <view class="share-to">

分享組件可以作爲公共組件被引用，下面是其他組件引用分享組件的方法。

 

 ref的作用是通過"refShare"可以調用分享組件裏面定義的方法。
