Security
⚠️ Please read the VULNERABILITIES document for a list of
fixed vulnerabilities
Please also read the SECURITY document for instructions on how to
securely configure your Web server for file uploads.
Setup
jQuery File Upload can be installed via NPM:
npm install blueimp-file-upload
This allows you to include jquery.fileupload.js and
its extensions via node_modules, e.g:
<script src="node_modules/blueimp-file-upload/js/jquery.fileupload.js"></script>
The widget can then be initialized on a file upload form the following way:
$('#fileupload').fileupload();
For further information, please refer to the following guides:
Requirements
Mandatory requirements
Optional requirements
Cross-domain requirements
Cross-domain File Uploads
using the
Iframe Transport plugin
require a redirect back to the origin server to retrieve the upload results. The
example implementation
makes use of
result.html
as a static redirect page for the origin server.
The repository also includes the
jQuery XDomainRequest Transport plugin,
which enables limited cross-domain AJAX requests in Microsoft Internet Explorer
8 and 9 (IE 10 supports cross-domain XHR requests).
The XDomainRequest object allows GET and POST requests only and doesn't support
file uploads. It is used on the
Demo to delete uploaded files
from the cross-domain demo file upload service.
