远程true无法在rails2.3.8中的表单中工作

Question

I am using ruby 1.8.7. I just wrote a simple form that sends ajax request to certain action using remote true, but it isn't seem to be working!

I have included jquery1.6.3.js and rails.js. The form is simple and looks like this:

<% form_tag("/click_button", :remote => true) do %>
  <%= text_field_tag "something" %>
  <%= submit_tag "Add" %>
<% end %>

The click_button method just renders the js

def click_button
  respond_to do |format|
    format.js
  end
end

The problem with is that when I click the button, there is no request to be seen in the console of the firebug, instead the page is being redirected to /click_button.erb and it gives an missing error template. Can anyone please help me with this?

[Edited] The generated html code is like this:

<form remote="true" method="post" action="/data_management/add_configuration_data">
  <input id="something" type="text" name="something">
  <input type="submit" value="Add" name="commit">
</form>

Answer 1

try this

  <% form_remote_for :xyz, :url => {:controller => "controller-name", :action => "action-name"} do |f| %>
    <%= text_field_tag "something" %>
    <%= submit_tag "Add" %>
  <% end %>

For rails 2.3.8 you have to use remote_form_for OR form_remote_tag instead :remote => true

<% remote_form_for("/click_button"e) do %>
  <%= text_field_tag "something" %>
  <%= submit_tag "Add" %>
<% end %>

It seems that the remote handler is not attached to the form. Double check that

1. the jQuery library is linked from the page and make sure the link works. Sometimes it's mispelled. Open the source and check it.
2. the rails.js file is linked from the page and the link works. Same as above.

3. Add the csrf_meta_tag tags in the page in the header section

    <%= csrf_meta_tag %>

我尝试做类似remote_true的操作，但是它似乎没有用，所以我找到了一种通过javascript解决此问题的方法。
