Ralph, you are looking for two different kinds of knowledge: 1. How to send an XMLHttpRequest. This is a jQuery question. The answer is usually jQuery.post or jQuery.ajax. You will have to include your authentication token in the post request if you are protecting against forgery. 2. How Rails responds to the XMLHttpRequest. This is simply handled by a controller action. Use something like if xhr? to make sure you are responding to an XMLHttpRequest if that's important to you. 3. How to render a response that you can then use to change the page. This is simply whatever you put in the response body. As someone previously noted, JSON may be easier and more flexible to use than XML. Then couple this with the success() callback in your jQuery .post or .ajax to change your DOM appropriately. This is not a cookbook solution, as all such applications are different. Hopefully, it's a starting point for your research and you'll find it easy to join Rails and jQuery.
