我正在 Rails 2.3.8 上开发项目，当用户在下拉菜单中选择特定选项时，我需要刷新整个网页。我怎样才能在轨道上做到这一点？

这是我的下拉菜单，

  <%= collection_select("country", "id", @countries , :id, :name, {:prompt => true}, :id => 'xx') %>
  <%= observe_field('xx', :url => { :controller => 'calendar', :action => 'update_country' },:update => 'app_header',:with => "'con=' + escape(value)")%>

它可以很好地加载国家/地区，那么我如何重新加载整个页面？请有人能给我解释一下吗？

只需将 html 选项添加到您的集合中 select , onchange => “重新加载页面的 JavaScript 代码”

<%= collection_select("country", "id", @countries , :id, :name, {:prompt => true}, :id => 'xx', :onchange => "location.href = '#{root_url}'") %>

Simply add a html option to your collection select , onchange => "Javascript code to reload the page"

<%= collection_select("country", "id", @countries , :id, :name, {:prompt => true}, :id => 'xx', :onchange => "location.href = '#{root_url}'") %>

或者您可以刷新当前页面：

<%= collection_select("country", "id", @countries , :id, :name, {:prompt => true}, :id => 'xx', :onchange => "location.href = window.location.href") %>

Or you can just refresh the current page:

<%= collection_select("country", "id", @countries , :id, :name, {:prompt => true}, :id => 'xx', :onchange => "location.href = window.location.href") %>
