[Javascript] Database and SQL

[Flávio Gomes]

  AJAX, "Asynchronous JavaScript and XML", that's the name of the 
technology used for loading "the values into a component without loading 
some other page".

  Or maybe, depending on your case, if is not there a need to change the 
values from the dropdown "onclick" you could already write (on your 
serverside language) the page/dropdown with the values there.
