You might get this error while integrating jquery in your appplication.Scripts will not get invoked.
I have to include Datepicker for a field in a page.
var $j = jQuery.noConflict(); $j(document).ready(function($) { });
Got the error "jQuery is not defined"
Just changed order of the script which i included in the application. The error got resolved :)-
<%= javascript_include_tag "http://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js" %>
<%= javascript_include_tag "http://ajax.googleapis.com/ajax/libs/jqueryui/1.8.17/jquery-ui.min.js" %>
<%= stylesheet_link_tag "http://ajax.googleapis.com/ajax/libs/jqueryui/1.8.17/themes/base/jquery-ui.css" %>
The order in which you load your scripts is important
