Chapter 5. RJS

If you picked up this book for the first time and skipped directly to this chapter, I don't blame you. And if you're the linear type and have read all the previous chapters, everything has been leading up to this: Ruby-generated JavaScript (RJS) is the capstone of Ajax in Rails.

In the last few chapters, practically all the Ajax examples have one thing in common: they work by receiving small snippets of HTML from the server and inserting them into the page. It's a delightfully simple approach, and it gets a ton done with a minimum of abstraction overhead. After all, we're building web applications, so everything will eventually become HTML anyway. Rails has a rich set of helpers for generating HTML, so why not simply render that on the server side and transfer it as is. But sometimes the simple approach isn't sufficientsometimes you need more flexibility.
