search for: observe_form

Hi all, I''m trying to understand the workings of the observe_form function. In my application I have a search form with a number of parameters, and I want to have a live search counter on screen, so as the user chooses different parameters, she can see a live count of how many search results match. What I''m not clear on is how to use the "with&...

This betrays my lack of javascript knowledge, but is it possible to watch a whole form for changes and activate some javascript when those changes occur without any remote request? That is, I want to do exactly what observe_form does, but without the ajax call actually happening. I realize I could use the form_tag :onchange parameter, but that seems to be incapable of doing things like updating a DOM element style. Currently I just put my javascript in :complete and have the ajax render :nothing => true, but that&...

...rking correctly. So any help is greatly appreciated. I ahve this code in my template: <% form_for :company_branch, @company_branch, :html => {:id => "company_branch_form"} do |f| %> <%= f.text_field :street1 %> <%= f.text_field :street2 %> <% end %> <%= observe_form("company_branch_form", :frequency => 1) %> The params I get when the form changes is: {"company_branch_id"=>"1", "action"=>"edit", "controller"=>"admin/company_branches/details"} This has NONE of the form value...

Hi there, I''ve been checking out RJS templates, and have been trying to use them with the observe_form helper. However, the form values are no longer being passed in the params (as soon as I point the action to the non-rjs and add the ''update'' clause everything is working again). Is this expected?

My observe_form is basically totally limp. I think it should update without hitting submit button but even if I hit it , it doesn''t change (doesn''t seem to post the data). Can anyone please take a look and see if I"m doing something wrong. TIA Form: <% start_form_tag({:action => &qu...

I want to use observe_form to automatically save notes in a text_area. This is the code I have: <form id=''notes_form''> <%= text_area :contact, :notes, :cols => 40, :rows => 10, :id =>''notes_text_area'' %> <%= observe_form(''note...

I made a pretty lengthy post on what I''m doing here: http://groups.google.com/group/rubyonrails-talk/browse_thread/thread/89a2b8e54a874dd9 Short version: I have a radio_button group of two. If one is clicked another pair of radio buttons is added, if the other is clicked it is removed. observe_form does not work for elements added after initial page load. observe_field does not work for radio_buttons except on the first ''click'' It was suggested that I stop observe_field before changes are made to the form then restart it. With much searching I found a Event.stopObserving m...

I have posted this previously also but haven''t received any help. So, if somebody could look into it and guide.. I want to validate the extension of files that I am uploading. Like I want only the doc/pdf files to be uploaded.. Thanks in advance. -- Posted via http://www.ruby-forum.com/.

Can anyone help with some strange error messages I''m getting on IE when using observe_form. I''ve written some code to observe a set of radio buttons and it all works fine in Firefox but when using IE about 20% of the calls return a request.status of 12152, ERROR_HTTP_INVALID_SERVER_RESPONSE (and the occasional 12030, ERROR_INTERNET_CONNECTION_ABORTED). It only happens on SSL p...

I''m using observe_form in a place that does not require any response from the server. So I do not use an update paramater. But without it webbrick hangs for a couple seconds and returns a status 500. On occasion, there will even be an exception in webbrick''s output if I change the form then quickly click a l...

I want to make use of a form_remote_tag to submit a form asynchronously. Easy done. However, we also want to add an observe_form tag to check for some value changes while the form is being entered. The observe_form tag needs a dom id to work on but I can''t see how to enter an html option for the dom id of the form on the form_remote_tag. Any ideas? Here is the form tag so far... <%=form_remote_tag :loading=&g...

Hi, I''ve got some Ajax stuff that shows more or less of a complex form based on a radio button selection. A "radio_handler" controller action is the action for a form handler. Some seemingly simple "replace_html" fires as a result of different radio buttons being chosen (which should then show more or less of the form). This all works just great on Mac Safari and

in some other language have a concept e.i "auto postback" So, in Ruby on rails is there any such option e.i "auto postback" or same as "auto postback" basically what i want ot do is that i have 2 select box One for "Industry" and other for "Chemical" 1st we show all the industry in "Industry" select box. if we select any 1 industry

I have been trying to pass a collection_select parameter and a text field parameter to observe_field so that it watches both the parameters simultaneously. but what i can see is , when i select some value from drop down and dont write anything in text field its giving correct results.parameters are also correct passed, but just after that if i write something in text field that value also get

Right now I have a simple form hooked up. Now that the form is smooth and functional, I want to add a feature that I''m not sure how to implement. After a user modifies a form, I''d like to have a visual cue appear somewhere to show that the form has been changed and needs to be saved. It could be a red div at the top of the screen - anything - it is doesn''t matter. Just

...hen this is made into Javascript, it wants to do something like parameters:''Form.serialize(''search_form'')=''+value It used to work fine and give me parameters:Form.serialize(''search_form'') I''m pretty sure the same thing happens with observe_form. Ideas? Thanks, Asa -- Posted via http://www.ruby-forum.com/.

Hi, I''m confused about how form verification with AJAX works. Let''s say I have a ''new.rhtml'' view that contains a form with two fields, and the form action is ''create''. Let''s assume that I also want to do some type of data validation on one of the two fields via AJAX before I submit the form. But since I''ve already

...javascript_include_tag :defaults %> </head> <body> <%= form_tag nil, { :id => ''search_form'' } %> <%= text_field ''recipe'', ''name'' %> <%= end_form_tag %> <div id="recipe"> </div> <%= observe_form :search_form, :frequency => 0.5, :update => ''recipe'', :url => { :action => ''search_ajax'' } %> </body> </html> below is the error i am getting Action Controller: Exception caught Showing *room/search.html.erb* where line *#...
