Vue File Uploader - Form Upload

The FileUploader component allows an end user to upload files to the server. This demo illustrates the use of the FileUploader within a web page. To select a file using the Open file dialog, click the Select photo button. Note that the Open file dialog only accepts image file types as the accept configuration property of the FileUploader is set to «image/*».

To see an example of server-side implementation, refer to the HTML Form Upload article for ASP.NET or PHP.

NOTE

This demo does not actually upload the selected file. To upload a file, submit the form. The form element should contain the action attribute, which holds the URL of the page providing server scenarios for saving uploaded files.
