rails link_to :remote | 易学教程

问题

I have the following:

<%= link_to my_path, method: :delete, confirm: 'Delete?', class: 'link-delete', 'data-message' => 'Are you sure?', 'data-severity' => 'danger', :remote => true do %>
  <i class="icon-trash"></i>
<% end %>

which brings up a Bootstrap Modal for confirmation, and I wanted to hook onto the ajax call that so that I can display a spinner or some kind of text.

I know that I can use unobtrusive javascript to listen to the click event like so, if I DON'T use ':remote => true' in my link_to

jQuery ->
  $('.link-delete').live 'click', (event) ->
    $('.link-delete').html("Loading...")  #THE MSG OR ANIMATION I WANT TO DISPLAY
    $.get(this.href, null, null, 'script')
   false

but not sure how to combine the two when using ':remote => true'

Any suggestions?

thanks for the help

回答1:

You can bind to ajax calls like this:

<%= link_to my_path, method: :delete, confirm: 'Delete?', class: 'link-delete', 'data-message' => 'Are you sure?', 'data-severity' => 'danger', :remote => true do %>
  <i class="icon-trash"></i>
<% end %>

$('.link-delete').bind('ajax:beforeSend', function() {
  $('#mySpinner').show();
});

$('.link-delete').bind('ajax:complete', function() {
  $('#mySpinner').hide();
});

You don't need to combine the two. Just use the format.js to call the javascript.

In your controller:

Controller

 def my_method
     #code here
     respond_to do |format|
      format.js  {}
     end
    end

my_method.html.erb

<div id = "link-delete"></div>

my_method.js.erb

$("#link-delete").html("<%= escape_javascript(render(:partial => "text_message"))%>");

_text_message.html.erb

<p>Loading...</p>
