"modal form" with bootstrap on rails works partially

On Rails 3.2.3, I have a form in a partial view, using bootstrap 2.0.2 modals

#myModal.modal
  .modal-header
    .close{"data-dismiss" => "modal"}= link_to "x", root_path
    %h3 Add Tags
  .modal-body
    = form_tag '/tagging', :remote => true do
      = text_field_tag 'tags_string', params[:tags_string]
      = hidden_field_tag 'id', params[:id]
      .modal-footer
        = submit_tag "Add tag", :class => "btn btn-primary"
  :javascript
    $(document).ready(function() {
      $('#myModal .btn.btn-primary').click(function() {
        $('#myModal').modal('hide');
        $('form').submit();
      });
    });

I the "main" page I've a link button to call the partial :

%td= link_to "Tag", tagging_path(:id => "#{repo.id}", :tags_string => "#{repo.tags}"), "data-toggle" => "modal", :class => "tag add-tag btn btn-primary

and the controller has the relative tagging method.

Now I have two problems:

  1. first

    when I click the button it display the form correctly but it leaves the "main" page (which I don't want), displaing the relative href (which is empty), as a background :

    http://localhost:3001/tagging?id=4f82cb8ef370ff0001000699&tags_string=

    that is generated by the 'tagging_path' in the link button. I cannot just call the modal like in bootstrap example :

    <a data-toggle="modal" href="#myModal" class="btn btn-primary btn-large">Launch demo modal</a>

    because I need to fill the controller/model with form params so ..., how can this be done ?

  2. second:

    when I click the "Add tag" button in the form, the database get the right content and everything works but the form doesn't disapear until I click "X" link, which is just a link to root_path and not a JS action.

    so it seems js is not working properly

    $(document).ready(function() {
  $('#myModal .btn.btn-primary').click(function() {
    $('#myModal').modal('hide');
    $('form').submit();
  });
});

UPDATE:

This is the generated html :

<div class='modal hide fade' id='myModal'>
    <div class='modal-header'>
        <div class='close' data-dismiss='modal'><a href="/">x</a></div>
            <h3>Add Tags</h3>
        </div>

        <div class='modal-body'>
        <form accept-charset="UTF-8" action="/tagging" data-remote="true" method="post"><div style="margin:0;padding:0;display:inline"><input name="utf8" type="hidden" value="&#x2713;" />
                <input name="authenticity_token" type="hidden" value="vlZaCIRV58BfDZ0xjYsefSEVL1LSpiI5UL1tgzbm/8o=" /></div>
            <input id="tags_string" name="tags_string" type="text" />
            <input id="id" name="id" type="hidden" />

            <div class='modal-footer'>
            <input class="btn btn-primary" name="commit" type="submit" value="Add tag" />
            </div>
        </form>
    </div>
</div>

<td>
    <a href="/tagging?id=4f82cb5cf370ff000100003a&amp;tags_string=ruby+web+framework" class="tag add-tag btn btn-primary" data-toggle="modal">Tag</a></td>
</tr>
<tr>
<td>

1) Use event.preventDefault() to stop the link action

2) Your selector needed a space. Or you can just leave .btn out entirely.

$(document).ready(function() {
    $('#myModal .btn-primary').click(function(e) {
        e.preventDefault();
        $('#myModal').modal('hide');
        $('form').submit();
    });
});

If you post the rendered HTML markup of your modal I can help with your selector since using the class is generally not a good idea if you want to capture a specific button click.

Edit given markup:

Okay, you can just make your button a button type instead of submit and select it by its name instead. If you use a submit you don't need to call form.submit, it does that by default. Using a button type gives you more control.

$('input[name="commit"]').click(function() {
    //$('form').submit();
    $('#myModal').modal('hide');        
});
