Drag drop uploader with html page

I want to create control, which uploads file to the server using JavaScript, with the following features

1. Drag drop support
2. Use only HTML and JavaScript(without any开发者_运维知识库 server side code)

This isn't going to be possible without any server side scripting to process the upload and save it on the server: http://robertnyman.com/2010/12/16/utilizing-the-html5-file-api-to-choose-upload-preview-and-see-progress-for-multiple-files

If you are familiar with node.js which is basically javascript , you can try using it along wiuth html5 elements instead of php or other server side languages to upload it to the server. But there is no way around a server side if you are going to uploade a file since it has to be stored somewhere.
