jQWidgets is a JavaScript framework for making web-based applications for PC and mobile devices. It is a very powerful and optimized framework, platform-independent, and widely supported. jqxFileUpload is a widget that can be used to select files and upload them to a server. It also supports automatic upload and multiple files upload.

The refresh() method is used to refresh the widget. i.e., it is used to set the button which explicitly uses another button to refresh the files. It does not take any parameter and does not return any value.

Syntax:

$('#jqxFileUpload').jqxFileUpload('refresh');

Linked Files: Download the jQWidgets from the link. In the HTML file, locate the script files in the downloaded folder.

<link type=”text/css” rel=”Stylesheet” href=”jqwidgets/styles/jqx.base.css” />
