Upload

Upload file widget by select or drag.

Note

  • Must set resReName to get correct data

  • multiple determine return array or one element

  • If enum or asyncData is set, it will be converted to fileList (nzFileList), and must initially guarantee a response property to indicate remote data and make sure resReName can be obtained correctly

  • Image preview: by default, it uses nzModal to show url or thumbUrl of file object
