Google CDN Jquery load not working

I currently have an ugly array of separate javascript files in one of my layouts and I'm trying to clean it up using the Google CDN.

Current state (horrible I know):

...css...  
<%= yield :head %>

<%= javascript_include_tag "https://ajax.googleapis.com/ajax/libs/jquery/1.4.3/jquery.min.js" %>
<script type="text/javascr开发者_运维问答ipt" src="http://cdn.jquerytools.org/1.2.5/all/jquery.tools.min.js"></script>
<%= javascript_include_tag "https://ajax.googleapis.com/ajax/libs/jqueryui/1.8.13/jquery-ui.min.js" %>
<%= javascript_include_tag "ui/jquery.ui.core", "ui/jquery.effects.core",
   "ui/jquery.effects.highlight", "ui/jquery.ui.widget", "ui/jquery.ui.tabs",
   "ui/jquery.ui.progressbar" %>
<%= javascript_include_tag "jquery.ui.stars.min", "application", "rails" %>

I tried replacing the 2nd from bottom tag (with the long list of files) with:

<%= javascript_include_tag "https://ajax.googleapis.com/ajax/libs/jqueryui/1.8.13/jquery-ui.min.js" %>

I am getting no luck with that - it seems as if the google file is not there at all (I checked my page source and it is loaded). What am I doing wrong here?

I don't know how to translate it into RAILS but this simple HTML should do the trick.

<script type="text/javascript" src="//ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script>
<script type="text/javascript">
    if(typeof jQuery == 'undefined') {
        //<![CDATA[
        document.write("<script src='/includes/jquery-1.4.2.min.js' type='text/javascript'><\/script>");
        //]]>
    }
</script>

This would assume that your jQuery file is stored on /includes/jquery-1.4.2.min.js.
On Google's CDN failure, local copy will get fetched.

Sorry to dredge up an old post, but I'm not sure the question was actually answered.

I had a similar problem as you did, and the solution was actually quite simple: I was not including the CSS. You can do so through Google's CDN as well:

<link href="http://ajax.googleapis.com/ajax/libs/jqueryui/1.7.2/themes/ui-lightness/jquery-ui.css" media="screen" rel="stylesheet" type="text/css" />

or

<%= stylesheet_link_tag 'http://ajax.googleapis.com/ajax/libs/jqueryui/1.7.2/themes/ui-lightness/jquery-ui.css' %>

Obviously this is for the ui-lightness theme; there are other themes available on the CDN (though not all of them). I'm sure you can find those with a quick Google search.
