js部分

// 是否预览
const previewVisible = ref(false)
// 图片url
const previewImage = ref('')
// 图片集合
const fileList = ref([])
// 图片id
const currentfileId = ref()

const handleCancel = () => {
   
  console.log("关闭预览图")
  previewVisible.value = false
}

const handlePreview = (file) => {
   
  console.log("预览操作")
  previewImage.value = file.url || file.thumbUrl
  previewVisible.value = true
}

const customRequest = async ({
    
                               action,
                               data,
                               file,
                               filename,
                               headers,
                               onError,
                               onProgress,
                               onSuccess,
                               withCredentials
                             }) => {
   
  const formData = new FormData()
  formData.append('file', file)
  const fileId = await fileApi.fileUploadDynamicReturnId(formData)
  emit('uploadDone', fileId)
  onSuccess({
   data: fileId}, file)
  // 加入到显示集合，此处直接赋值，因为我设置的只能有一张图，fileList为数组[]，file为对象{}
  fileList.value = [file]
  currentfileId.value = fileId
}

const del = (file) => {
   
  fileApi.fileDelete([{
    id: currentfileId.value }]).then((res) => {
   
    // 同时清空 fileList
    fileList.value = []
    currentfileId.value = ''
  })
}
