Hi

You can use button_to_function with remote_function like

<%= button_to_function 'Click me', remote_function(:url=>{:action => 'uploadFile', :controller => 'UploadController'}} =>

remote_function is same options as link_to_remote and generates the an ajax call. You'll want to read about rjs for the final step of your problem

Good Luck :wink: -Ganesh K
