Form support in Vue Uploader component
16 Mar 202324 minutes to read
The uploader component works with HTML form like default file input.
The following configuration is must to make the uploader work inside the form.
* `saveUrl` and `removeUrl` must be null.
* `autoUpload` must be disabled.
* `name` attribute must be added in input element.
The selected or dropped files are received as a collection in form action when the form is submitted. The form action handles the server-side operations that manage the file upload process. When you reset the form, the file list and data will be cleared.
