uni-app中的uni-file-picker可单独上传照片或视频,但不支持同时上传照片和视频。本篇博客使用image标签和video标签实现移动端(H5+app+小程序)中照片和视频的同时上传。
本篇博客采用的是照片和视频的单独上传,但可同时展示,支持照片和视频的删除,其中照片和视频均是调用的后端的接口,上传至服务器中,大家可根据个人需要灵活存储照片和视频。
实现效果:
实现代码 :
将照片和视频区分上传,并单独处理,照片采用image标签,视频采用video标签。
<template><!-- 上传视频或者图片 --><view class="up-page"><!--图片--><view class="show-box" v-for="(item, index) in imageList" :key="index"><imageclass="full":src="item":data-src="image"@tap="previewImage(item)"></image><view class="delect-icon" @tap="delect(index)"><image class="full" :src="clearIcon" mode=""></image></view></view><!--视频--><view class="show-box" v-for="(item1, index1) in videoList" :key="index1"><video class="full" :src="item1"></video><view class="delect-icon" @tap="delectVideo(index1)"><image class="full" :src="clearIcon" mode=""></image></view></view><view v-if="VideoOfImagesShow" @tap="chooseVideoImage" class="box-mode"><image class="full" :src="selectfile" mode=""></image></view></view>
</template>
对照片和视频分别进行上传、删除等操作,避免index值出现错乱,出现错删和误删。
配置项可进行父组件的传值灵活设置。
此处处理的是将后端上传后的照片或视频id传递出去,此处可根据个人需求灵活设置。但需注意的是,imageList和videoList不要轻易改变,此处是专门使用了对应的id数组进行了重新定义。

对视频和照片的尺寸进行定义。可灵活根据个人需求进行设置。
<style lang="scss">
/* 统一上传后显示的盒子宽高比 */
.box-mode {width: 20vw;height: 20vw;border-radius: 8rpx;overflow: hidden;
}.full {width: 100%;height: 100%;
}.up-page {display: flex;flex-wrap: wrap;display: flex;width: 100%;.show-box:nth-child(3n) {margin-right: 0;}.show-box {position: relative;margin-bottom: 4vw;margin-right: 4vw;@extend .box-mode;.delect-icon {height: 40rpx;width: 40rpx;position: absolute;right: 0rpx;top: 0rpx;z-index: 1000;}}
}
</style>
以上三部分可组合为一个完整的vue组件,可在父组件中使用。父组件的使用实例
<FileUpload :uploadConfig="uploadConfig" @getImgUploadIds="uploadImgIds($event)" @getVideoUploadIds="uploadVideoIds($event)"/>const uploadConfig = ref({maxCount: 3,exParam: 'imgArr'
})// 获取图片的ids
function uploadImgIds(val) {console.log(val)
}
// 获取视频的ids
function uploadVideoIds(val) {console.log(val)
}
