html - 隐藏 Rails 上 will_paginate 函数中使用的 "..."

Question

由于值的数量，我正在使用 will_paginate，但我不知道如何隐藏“...”部分和后面的页码。这就是我目前拥有的:

这是我想要的:

<1 2 3 4>
点击下一步会给我< 2 3 4 5 >(请注意，在两者中，我们没有看到“..”后跟 95 96 97。)

知道如何做到这一点吗？这是相关的 HTML:

<div class="pagination full">
  <span class="previous_page disabled">&lt; 前へ</span>
  <em class="current">1</em>
  <a rel="next" href="/student/search?page=2">2</a>
  <a href="/student/search?page=3">3</a>
  <a href="/student/search?page=4">4</a>
  <a href="/student/search?page=5">5</a>
  <a href="/student/search?page=6">6</a>
  <a href="/student/search?page=7">7</a>
  <a href="/student/search?page=8">8</a>
  <a href="/student/search?page=9">9</a>
  <span class="gap">…</span>
  <a href="/student/search?page=95">95</a>
  <a href="/student/search?page=96">96</a>
  <a href="/student/search?page=97">97</a>
  <a class="next_page" rel="next" href="/student/search?page=2">次へ &gt;</a>
</div>

谢谢!

您需要为 will_paginate 创建一个自定义渲染器。 will_paginate 助手接受一个参数 renderer，如下所示:

<%= will_paginate(@users, :renderer => UserPaginationRenderer) %>

您只需要自己实现UserPaginationRenderer，使用您自己的规则，比如只显示 4 个链接等等。有很多关于此的信息和文章:
