Is the observe_field (ActionView::Helpers::PrototypeHelper ) can be apply to any html tag? (such as div) I tried to apply ''observe_field'' to observe the content of <div> tag, but, as the observed <div>''s content was changed, there was nothing happend. for example (in test.rhtml): <%= link_to_remote "test", :update=>"content1",

ruby script/generate controller Tools::Search - ok in views/layouts/application.rhtml: <%= render_component :controller => ''tools/search'', :action => ''searchbox'', :params => {:context => ''header-section''} %> in

Let''s say I have a catalog with hotels. Each hotel belongs to a category (4-star, 5-star etc.) This is it''s official category.However, there is also a category that users assign and a category that "independent reviewers" assign. So I have this: hotels { id, category_id, reviewer_category, user_category } categories { id, name } class Hotel <

No problem, also check out bindAsEventListener for attaching functions to element events, still maintaining your object as the "this" in the event handler scope at the same time having access to the originating "event" object.

Hi. I''m using prototype.js V1.6.0_rc0. I''ve successfully used Element.addMethods() to add some additional functionality to my forms ... Element.addMethods(''FORM'', { ... }); So far so good. I now want to add a new property to all forms. Is there an equivalent Element.addProperty(''FORM'', { ... }); technique I could use? As readAttribute /

Hi folks, I''m pretty new to javascript and prototype, so I just want to get some peer-review on a function I wrote that makes a handy (at least, it seems handy) way to set a group of attributes on an element easily. Object.extend(Element.prototype, { setAttributes: function(attrs) { var el = this; $H(attrs).each( function(attr) { el.setAttribute(attr[0], attr[1]);

No comment on the usefulness of your function, as I''ve yet to try it. But for the "this" scope problem, try this... (removed your var and added the bind(this) after the function declaration. I didn''t test it though so you might want to give it whirl. It might introduce a different scope problem with the "attr" var but I think it should work.

I want to take an existing DOM object and extend it with some functionality. I know there''s a way to do this with prototype. Unfortunately, I''m not entirely sure how to do this. Basically, I want to take an existing DOM object and turn it into a ''widget'' by adding some functionality. say we have a span: <span id="blah">some text

Hi, I''m relatively new to javascript programming, and OOP in general, so please be nice to me ;) My question is: I''d like to extend the Form class in prototype to have a Disable function that will disable all of the fields in a form. I''ve already written a function to do this, but I''d like to include it in my own library so I can access it easily and also

HI friends, After updating ruby 1.8 to ruby1.9.1.......& on firing script/server to start a server, I am getting the following errror..... /home/HUNT/WEBlog/config/boot.rb:86:in `load_rubygems'': undefined method `>='' for nil:NilClass (NoMethodError) from /home/HUNT/WEBlog/config/boot.rb:52:in `load_initializer'' from /home/HUNT/WEBlog/config/boot.rb:38:in

Dear list, this is a re-post of my post to r-help on 2012-30-11. Duncan Murdoch did provide a great pointer to a possible workaround, but I'm still eager to check out other ways. So I hope it's okay to get this out on r-devel now as well: // IN SHORT // What are possible workarounds to "consolidate" documentation for S4 methods that are scattered across different packages

Hello, * I read in a server weblog with read.table. -> OK. * I look for the downloaded-size-values (filesize of the download) -> OK * I found "-" and wanted to substitute them with "0" and used: weblog$V8[ weblog$V8 == "-" ] <- 0 -> OK * checked the contents on "-" vs. "0" and found all "-" substituted by

I am disappointed about the (seeming) lack of Unicode support in Rails. Is there a howto about working the most important limitations? For example, figuring out the length of an entered word: "???".length() will return 6, not 3. So if there is a maximum number of characters a user is allowed to enter, this won''t work as it should -- it treats strings as byte arrays instead

Hello, again I'm on my weblog-script... having problems...

Does anyone know why the weblog at http://weblog.rubyonrails.org/ is often messed up, with the first or first and second topics left-shifted and melded with the Rails logo, the Live Search box and the page''s menu? This happens on all my boxes that run Internet Explorer 6 (IE6). I checked it on Firefox and the page appears correctly. While it''s easy to argue "just use

Hi! 1) planet.netfilter.org As some of you have already noticed, the link bar on the top of the netfilter homepage has now one additional link: "planet". http://planet.netfilter.org/ is a aggregator for RSS feeds of the blogs/diaries/journals[1] of developers related to the netfilter project.
