File Uploader

Async Upload


In this demo, the FileUploader component is configured for asynchronous upload. Use the File types drop-down menu to select acceptable file types for the Open file dialog. The Upload mode drop-down menu allows you to specify whether the file is uploaded on a button click or instantly after the file has been selected. In addition, you can specify whether the FileUploader allows multiple file selection.

To select files, click the Select file button or drop the files directly on the component. If the upload mode is «useButtons», you must click the Upload button or a corresponding button for each file to initiate upload.

NOTE: This demo does not actually upload files. To upload files, assign the URL of a page providing server scenarios for saving uploaded files to the uploadUrl configuration property of the component.
