  1. POrails best practices where to place unobtrusive javascript
    text
    copied!<p>my rails applications (all 2.3.5) use a total mix of inline javascript, rjs, prototype and jquery. Let's call it learning or growing pains. Lately i have been more and more infatuated with unobtrusive javascript. It makes your html clean, in the same way css cleaned it up.</p> <p>But most examples i have seen are small examples, and they put all javascript(jquery) inside application.js</p> <p>Now i have a pretty big application, and i am thinking up ways to structure my js. I like somehow that my script is still close to the view, so i am thinking something like</p> <pre><code>orders.html.erb orders.js </code></pre> <p>where orders.js contains the unobtrusive javascript specific to that view. But maybe that's just me being too conservative :)</p> <p>I have read some posts by Yehuda Katz about this very problem <a href="http://yehudakatz.com/2007/05/17/jquery-on-rails-a-fresh-approach/" rel="noreferrer">here</a> and <a href="http://yehudakatz.com/2007/05/25/10/" rel="noreferrer">here</a>, where he tackles this problem. It will go through your js-files and only load those relevant to your view. But alas i can't find a current implementation.</p> <p>So my questions:</p> <ul> <li>how do you best structure your unobtrusive javascript; manage your code, how do you make sure that it is obvious from the html what something is supposed to do. I guess good class names go a long way :)</li> <li>how do you arrange your files, load them all in? just a few? do you use <code>content_for :script</code> or <code>javascript_include_tag</code> in your view to load the relevant scripts. Or ... ?</li> <li>do you write very generic functions (like a delete), with parameters (add extra attributes?), or do you write very specific functions (DRY?). I know in Rails 3 there is a standard set, and everything is unobtrusive there. But how to start in Rails 2.3.5?</li> </ul> <p>In short: what are the best practices for doing unobtrusive javascript in rails? :)</p>
