Properly loading JQuery on Rails (object has no method) -

-

i working on course posted @ http://schneems.com/ut-rails. here app working with: https://github.com/schneems/ruby_javascript_data_viz.git.

i using rails 3.2.6 , ruby version 2.0.0p247.

i have cloned file desktop, installed bundle, , set database. when use console (chrome) see if jquery working, error:

> $('body').hide();   type error:  object #<htmlbodyelement> has no method 'hide'

when view page source see if jquery loading, can see line:

<script src="/assets/application.js?body=1" type="text/javascript"></script>

however, don't see jquery. missing here?

i have searched issue, , have found many similar questions, can't seem find me going.

thank you!!

make sure jquery plugin loaded , document ready before using hide() function.

wrap code in

$(function() {     $('body').hide(); }

and try.

Does Firefox offer AppleScript support to get URL of windows? -

-
i trying write applescript that, among other things, gets url of every open webpage in firefox. in safari (and chrome), done simply: tell application "safari" return url of every tab in every window however, seems me firefox offers no real applescript support, such getting url of tab or window. when google terms "firefox" , "applescript" together, firefox bug requests asking applescript support restored, last updated in 2010 or 2011 (like this , this ). am right in thinking, then, firefox no longer offers proper applescript support? realize there semi-workarounds, such simulating key-commands in applescript, aren't practical purposes. to see of applescript commands firefox responds to, launch applescript editor, select menu file > open dictionary... , , choose firefox application. you'll find you're expecting: firefox doesn't offer useful applescript commands.
