S3 Uploader Rails Example¶ ↑

Based on the great jQuery File Upload plugin: blueimp.github.com/jQuery-File-Upload/

Features:

• No flash :)

• File Progress Indicator (Chrome, Firefox, Safari)

• Multiple file selection, parallel upload (Chrome, Firefox, Safari)

• Drag’n’Drop (Firefox 4+, Safari 5+ - buggy on windows, Google Chrome)

• Internet Explorer and Opera fall back to iframe transport single file uploads

Tested with Chrome, Firefox, Safari, Opera and IE 7

Get’s around S3’s lacking cross domain access header support by storing the upload form on s3, embedded in an iframe. Upload progress is displayed on the host server by utilizing postMessage browser communication.
