How to verify whether the user has submitted or not when the elementUI upload component clicks submit?

how to verify that it has been uploaded after clicking the submit button?


look at the status returned by the backend, ah, if you upload a file to the backend, but the backend does not return the status to you


upload will return the url, of an image. Just judge whether the image url is empty

.
MySQL Query : SELECT * FROM `codeshelper`.`v9_news` WHERE status=99 AND catid='6' ORDER BY rand() LIMIT 5
MySQL Error : Disk full (/tmp/#sql-temptable-64f5-1e44ee9-44ad0.MAI); waiting for someone to free some space... (errno: 28 "No space left on device")
