页面引入：

import UploadVideo from '@c/UploadVideo'

components: { UploadVideo }

<upload-video
:videos="videoInfo.allVideo"
:videoBaseUrl="IMAGEURL"
@delete="deleteVideo"
@change="getVideo" >
</upload-video>
data数据：

videoInfo: {
allVideo: [],
deleteVideo: []
}
视频上传：（此处只是上传到暂存区，真正上传是在提交表单时）

getVideo(event) {
this.videoInfo.allVideo = event
}
视频删除：

deleteVideo(index) {
const video = this.videoInfo.allVideo[index]
if (video.videoLink) {
this.videoInfo.deleteVideo.push(video)
}
this.videoInfo.allVideo.splice(index, 1)
}
在提交表单时上传：

uploadFiles() {
const uploadList = []
this.videoInfo.allVideo.map(item => {
console.log(item, 'video')
const videoFile = new FormData()
if (!item.videoLink) {
videoFile.append('file', item.videoFile.raw)
videoFile.append('fileTag', 'video')
uploadList.push(
new Promise((resolve, reject) => {
return ImgServe.uploadSingleFile(videoFile).then(res => {
if (res.data.code === 200) {
resolve(res.data.data)
} else {
this.$message('上传视频失败！')
}
})
})
)
}
})
return Promise.all(uploadList)
}

*:分开上传是为了杜绝服务器脏数据
ImgServe.uploadSingleFile(videoFile)这儿是上传到服务器的接口，替换为自己的写法即可
