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">
<image
class="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。

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)
}
