I've tried to install JQuery a couple of times now, and I've followed the steps for Rails UJS mentioned here:
The last time I went ahead and added jQuery UI as well:
$ rails generate jquery:install --ui
remove public/javascripts/prototype.js remove public/javascripts/effects.js remove public/javascripts/dragdrop.js remove public/javascripts/controls.js copying jQuery (1.6.1) identical public/javascripts/jquery.js identical public/javascripts/jquery.min.js copying jQuery UI (1.8.12) create public/javascripts/jquery-ui.js create public/javascripts/jquery-ui.min.js copying jQuery UJS adapter (dad698) remove public/javascripts/rails.js identical public/javascripts/jquery_ujs.js
As you can see, jQuery was already installed. However, I'm trying to follow the Getting Started tutorial which ahead a "Hello world" alert to all hyperlinks on the page, and nothing happens when I click a link. Here's what's in the <head> of my layout:
<%= javascript_include_tag :defaults %> <%= csrf_meta_tag %> <script type="text/javascript" charset="utf-8"> $("a").click(function() { alert("Hello world!"); }); </script>
Firebug is showing that that function is being called on page load, but when I click this link, it just reloads the page:
<a href="">My Link</a>
When I view the source, I see the following in the head:
<script src="/javascripts/jquery.js?1306339461" type="text/ javascript"></script> <script src="/javascripts/jquery-ui.js?1306344213" type="text/ javascript"></script> <script src="/javascripts/jquery_ujs.js?1306339461" type="text/ javascript"></script> <meta name="csrf-param" content="authenticity_token"/> <meta name="csrf-token" content="kCLegMZ7rgxMMlXnha5DQ2/8A6hMR9mEBX0XWFJFGSw="/> <script type="text/javascript" charset="utf-8"> $("a").click(function() { alert("Hello world!"); }); </script>
Any ideas as to what I'm missing? I've tried both commenting out and uncommenting this line in application.rb:
config.action_view.javascript_expansions[:defaults] = %w(jquery rails)
