jquery - 着陆页的不同变体

Question

所以我有一些模拟，以及着陆页的一些差异变体，有没有一种方法可以让我在每次加载时都显示不同的着陆页变体？

landingpage.html.erb

<%= render "shared/header" %>

<%# Begin background image cycler on landing page %>
<div id="background_cycler" >

  <script type="text/javascript">
$('#background_cycler').hide();//hide the background while the images load, ready to fade in later
</script>

<%= image_tag("background-guys-game.png", alt: "") %>
<%= image_tag("background-neutral.png",  class: "active", alt: "") %>
<%= image_tag("background-girls.png",  alt: "") %>
<%= image_tag("bg-wheel.png",  alt: "") %>
<%= image_tag("bg-train.png",  alt: "") %>
<%= image_tag("bg-girls2.png",  alt: "") %>
<%= image_tag("bg-room.png",  alt: "") %>

</div>
<%# End of background image cycler on landing page %>

<div id="landing_page">

Answer 1

super 简单的版本，如果你不需要做任何花哨的事情。

# PagesController
def landing
  number = rand(1) + 1
  render "landing_#{number}"
end

浏览量

# app/views/page/landing_1.html.erb
# app/views/page/landing_2.html.erb

如果您不想在 Rails 中进行跟踪工作，可以在 Google Analytic 中完成。
