Page is a not externally linkable

I came across some javaScript and wonder if I can go without it.
If you want to update the page immediately when the user selects a dropdown value, you have to use client side scripting (JavaScript). Like I said, though, don't rely on that value. Consider it just a progressive enhancement, and perform the form processing server side.
