* @version 4.2.8
|
*
|
* File input styled for Bootstrap 3.0 that utilizes HTML5 File Input's advanced
|
* features including the FileReader API.
|
*
|
* The plugin drastically enhances the HTML file input to preview multiple files on the client before
|
* upload. In addition it provides the ability to preview content of images, text, videos, audio, html,
|
* flash and other objects. It also offers the ability to upload and delete files using AJAX, and add
|
* files in batches (i.e. preview, append, or remove before upload).
