有关，当我点击一个按钮，我的控制器所得jQuery函数某些原因被调用两次。由于js函数被调用的切换，这是一个问题，因为它会导致code跳入水中拿出来看。

For some reason when I click on a button, my controller and the resulting jquery function gets called twice. Since the js function being called is toggle, this is a problem as it causes the code to jump in and out of view.

下面的形式：

Unseen Notifications: <%=  current_user.notification_unseen %> </div>
                <%= button_to "show", {:action => "seen", :controller=>"notifications"}, :remote => true %>

下面是控制器：

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

下面是jQuery的：

Here is the jquery:

$("div#notifications").toggle();
$("div#count").html("<%= escape_javascript( render :partial => 'notifications/count')%>");

我在为什么在地球上，这将可能发生的损失。我一直很小心，不要双击，不知道如何prevent它。任何建议，将不胜AP preicated。

I am at a loss for why on earth this would possibly happen. I have been very careful not to double click and don't know how to prevent it. Any suggestions would be greatly appreicated.

推荐答案

我最近类似这样的问题之前，我有2个的jQuery库包括在内。特别是要检查您只有jquery_ujs.js而不是的jquery.js。看来，当你包括他们的某些JS函数调用两次一样。

I had a recent problem like this before, when I had 2 jquery libraries included. In particular, check that you only have jquery_ujs.js and not jquery.js. Seems like when you include both of them certain js functions are called twice.

希望这有助于！
