[Javascript] Browse and Upload file

[Reuben D Budiardja]

Hi,
Does anyone know how to upload file using Web Browser as the interface?

I want to do a web page, where you can click on a button, and then you can 
browse the local directories of the person who are browsing the page, and 
upload a selected file to the web server. Any pointer on how to do that will 
be greatly appreciated. 

Thanks.
