Where I show the most inefficient way to duplicate HTML rendering for JavaScript XHR form validation callbacks.

Because Rails' Unobstrusive JavaScript (UJS) driver rails.js and jQuery won't execute any JavaScript in XMLHttpRequest's response bodies when the status code is 400 or 424 or something similar, I had to instruct the client (jQuery) myself to render error messages on form validation.

This is my first attempt to do so: instead of a JS request, respond with JSON and do the interface changes client-side. Problem is, the JavaScript code is sent to the client only once, hence ERB view templates aren't available during execution. I couldn't just use Rails helpers this way to refactor rendering flash messages. The HTML was spread across three places then: create.html.erb to handle synchroneous requests and render both flash messages and form validation error, to render errors and lastly create.js.erb to render success messages and insert the new entry.

It worked, and it was a fun ride since I didn't

Where, instead of my inefficient approach, I execute XHR JavaScript responses. Behaves just like JangoSteve said it should for 400 or 424 HTTP response status codes.

Binds the event on $(document) so that dynamically created forms will be affected, too.

nvALT Preview Template featuring relative paths

Run this from your terminal to execute the setup script. It creates the directory and downloads the template right into this new folder.

curl -s | bash 

Aferwards, you can change the base directory in ~/Library/Application\ Support/nvALT/template.html as expected.

Paste this into a playground and see what happens with the two client code examples at the bottom. Should work out of the box.
