However, I did not find the justification for Rails switching from prototype to jQuery convincing. The observer example was not less verbose. I don’t see an advantage of Rails being no longer prototype oriented. I don’t consider using jQuery to be framework agnostic, as it depends on the jQuery framework.

Maybe I am missing that, unlike the prototype support, Rails is decoupled from jQuery, as it does not have jQuery dependent helpers. Maybe that’s it. I was not happy when I first learned Rails that it was prototype dependent. However, once using it, taking it away is a decision I disagree with.

I also disagree that it’s a positive that the jQuery way, forces developers to have a deeper JavaScript knowledge than in the past. There are a number of systems to gloss over JavaScript, gwt, extJS, and jQuery. JavaScript is a little clunky, and the DOM api is definitely clunky.

My hope would be that a JS gloss framework became so popular that it was incorporated natively in browsers. For instance, observers could be added to the JavaScript foundation. Rails selection of prototype, brings prototype almost to a justifiable standard as a candidate for such inclusion. Abandoning prototype, and switching frameworks undermines this hope.

It defeats the purpose as far as I can tell.

As I follow this tutorial, it seems that my _path helper url value doesn’t get interpolated in the javascript.

For example, in your tutorial,
1
2
3
4
5
6
7
8
9
10
// Append the function to the “document ready” chain
jQuery(function($) {
// when the #search field changes
$(“#search”).change(function() {
// make a POST call and replace the content
$.post(, function(data) {
$(“#results”).html(data);
});
});
})

the live_search_path does not get translated into an actual path.

Please help.

There’s a grammatical mistake I found in the “So What?” section. You have “what does this means”, but it should be “what does this mean”. Any time you have something like “do”, “does”, or “will”, etc. in front of the verb, you would use “mean” instead of “means”. “This means…” vs. “What does this mean?” or “This does mean…”. Hope that helps.

I have acollege project to integrate into / enhance a Rails 3 scaffold app with Ajax, JQuery, dynamic DOM update,CSS, etc.. Do you know of any other papers that describe how to go about this.

Look forward to your response.
