I originally had my view look something like: \<% @heading = “Bugs” %\> \<%= link\_to ‘Bug table’, :action =\> ‘bug\_table’ %\> \<% for bug in @bugs %\> [etc., table] But then I changed it to: \<% @heading = “Bugs” %\> \<%= javascript\_include\_tag :defaults %\> ← new line \<%= link\_to ‘Bug table’, :action =\> ‘bug\_table’ %\> | | | \<% for bug in @bugs %\> [etc., table] and moved everything between into public/javascripts/application.js. Back when all the JS was in my view.rhtml, everything worked fine. Now that it’s in application.js, none of the functions do anything – I suspect that they’re not being loaded, somehow. When I view source for the rendered page, I see [Bug table](https://www.ruby-forum.com/bugs/bug_table) | | | [etc.] And, when I load up application.js?1191286272 and view its source, sure enough, there’s my java-script, just as I’d expect. So… what am I doing wrong? Thanks! P.S. Tried to Google + seach archives for this but, apparently, my search-fu is weak – Google got me nothing, while this-forum returned 100s of hits, none of which seemed to address this issue (I searched on +javascript +“not.loaded”) Hints there would be helpful, too 🙂 ---

Ping? 2 weeks and no one knows…? Summary: - When I have the javascript code in my aplication.rhtml, it all works fine. - When I move javascript code to public/javascripts/application.js and insert %= javascript\_include\_tag :defaults %\> into my application.rhtml, none of the javascript calls work. - [http://locahost:3000/javascripts/application.js](http://locahost:3000/javascripts/application.js) returns a page that contains all of the expected javascript. Thanks! ---

Go get Firebug: [http://www.getfirebug.com](http://www.getfirebug.com) You’re obviously including the javascript into your page, it’s just not getting initialized properly. Jason ---

(Maybe I’m not clear what I need to check to see that it’s “initialized”…?) Just as a sanity check, I put the js back in the main file, and verified: sure enough, all works correctly. Pulled it back out, no workie. Ok, so where in firebug do I look to see what is different? For what am I looking? Thanks! ---

If there are no errors in the Console, then we’ll need to see what you are trying to do. The code you’ve posted doesn’t help with solving the problem. Jason ---

Basically, you’re code is not executing. I get the feeling that it’s supposed to “just run”. This won’t happen in a file because the DOM is not yet loaded when the script is pulled in. It works in-line because javascript is run _after_ the DOM is loaded. You’ll need to wrap the code up in a function that gets called onload (any time after DOM is loaded, really). Jason ---

Again, if I put the javascript in the main source, it all works perfectly. If I use the javascript tags & js in its own file, it doesn’t work. I’m not sure what parts you want to see. Should I upload a zip-folder with some key bits? Also, Fred, I’m not sure what you’re telling me about breakpoints. I’m new to firebug, could you be explicit? Thanks!
