I've tried to install JQuery a couple of times now, and I've followed
the steps for Rails UJS mentioned here:
https://github.com/rails/jquery-ujs
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)
