``` For further information, please refer to the following guides: - [Main documentation page](https://github.com/blueimp/jQuery-File-Upload/wiki) - [List of all available Options](https://github.com/blueimp/jQuery-File-Upload/wiki/Options) - [The plugin API](https://github.com/blueimp/jQuery-File-Upload/wiki/API) - [How to setup the plugin on your website](https://github.com/blueimp/jQuery-File-Upload/wiki/Setup) - [How to use only the basic plugin.](https://github.com/blueimp/jQuery-File-Upload/wiki/Basic-plugin) ## Requirements ### Mandatory requirements - [jQuery](https://jquery.com/) v1.7+ - [jQuery UI widget factory](https://api.jqueryui.com/jQuery.widget/) v1.9+ (included): Required for the basic File Upload plugin, but very lightweight without any other dependencies from the jQuery UI suite. - [jQuery Iframe Transport plugin](https://github.com/blueimp/jQuery-File-Upload/blob/master/js/jquery.iframe-transport.js) (included): Required for [browsers without XHR file upload support](https://github.com/blueimp/jQuery-File-Upload/wiki/Browser-support). ### Optional requirements - [JavaScript Templates engine](https://github.com/blueimp/JavaScript-Templates) v3+: Used to render the selected and uploaded files. - [JavaScript Load Image library](https://github.com/blueimp/JavaScript-Load-Image) v2+: Required for the image previews and resizing functionality. - [JavaScript Canvas to Blob polyfill](https://github.com/blueimp/JavaScript-Canvas-to-Blob) v3+:Required for the resizing functionality. - [blueimp Gallery](https://github.com/blueimp/Gallery) v2+: Used to display the uploaded images in a lightbox. - [Bootstrap](https://getbootstrap.com/) v3+: Used for the demo design. - [Glyphicons](https://glyphicons.com/) Icon set used by Bootstrap. ### Cross-domain requirements [Cross-domain File Uploads](https://github.com/blueimp/jQuery-File-Upload/wiki/Cross-domain-uploads) using the [Iframe Transport plugin](https://github.com/blueimp/jQuery-File-Upload/blob/master/js/jquery.iframe-transport.js) require a redirect back to the origin server to retrieve the upload results. The [example implementation](https://github.com/blueimp/jQuery-File-Upload/blob/master/js/main.js) makes use of [result.html](https://github.com/blueimp/jQuery-File-Upload/blob/master/cors/result.html) as a static redirect page for the origin server. The repository also includes the [jQuery XDomainRequest Transport plugin](https://github.com/blueimp/jQuery-File-Upload/blob/master/js/cors/jquery.xdr-transport.js), 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](https://blueimp.github.io/jQuery-File-Upload/) to delete uploaded files from the cross-domain demo file upload service. ## Browsers ### Desktop browsers The File Upload plugin is regularly tested with the latest browser versions and supports the following minimal versions: - Google Chrome - Apple Safari 4.0+ - Mozilla Firefox 3.0+ - Opera 11.0+ - Microsoft Internet Explorer 6.0+ ### Mobile browsers The File Upload plugin has been tested with and supports the following mobile browsers: - Apple Safari on iOS 6.0+ - Google Chrome on iOS 6.0+ - Google Chrome on Android 4.0+ - Default Browser on Android 2.3+ - Opera Mobile 12.0+ ### Extended browser support information For a detailed overview of the features supported by each browser version and known operating system / browser bugs, please have a look at the [Extended browser support information](https://github.com/blueimp/jQuery-File-Upload/wiki/Browser-support). ## Testing The project comes with three sets of tests: 1. Code linting using [ESLint](https://eslint.org/). 2. Unit tests using [Mocha](https://mochajs.org/). 3. End-to-end tests using [blueimp/wdio](https://github.com/blueimp/wdio).
