Upload without inserting e-Mail and password

I studied the tutorial about the "saver" application provided by dropbox. The code provided in the tutorial (build a user styled button to upload a file by url) works pretty well. Unfortunately I couldn't figure out a possibilaty to upload a file without inserting an e-mail-address or password.

To be more precisely: A file should be uploaded to my account by only clicking a user designed button e.g. "Upload". Any idea?

The Saver lets a user save a file to their Dropbox, so it saves to whatever account the user is logged in as.

It sounds like you always want to upload to a single Dropbox account (yours), no matter what user is visiting your website. If that's the case, you'll need to send the file to your own server and from there write to your account using the https://www.dropbox.com/developers/core. It's possible to upload directly from the browser, but to do that you would need to expose the credentials (OAuth access token) for your account to all the user's of your app, which is a security non-starter.
