uniapp使用uview开发项目时 upload 上传组件很方便,但是如果同一个页面上传组件多了容易混乱,每次使用都需要重复很多代码,有没有办法复用一下呢
使用
<uploadimg :maxCount="3" :widht="220" :height="220" @getdata="getimg">
<view class="upload-btn">
<u-icon name="camera-fill" color="#ccc" size="40"></u-icon>
<view class="upload-tips">
{{$t('add.photos')}}
</view>
</view>
</uploadimg>
封装代码
<template>
<u-upload :width='width+"rpx"' :height='height+"rpx"' :fileList="fileList1" @afterRead="afterRead($event)"
@delete="deletePic" name="1" :maxCount="maxCount">
<slot></slot>
</u-upload>
</template>
