ruby - 如何使用 Mechanize Ruby 模拟跨度点击？

Question

我有一个包含页面列表的网页:

<div class="pager">    
  <span class="current_page">1</span>
  <span class="page" samo:page="2">2</span>
  <span class="page" samo:page="3">3</span>
  <span class="page" samo:page="4">4</span>
  <span class="page" samo:page="5">5</span>
  <span class="page" samo:page="6">6</span>
  <span class="page" samo:page="7">7</span>
  <span class="page" samo:page="8">8</span>
  <span class="page" samo:page="9">9</span>
  <span class="page" samo:page="10">10</span>
  <span class="page" samo:page="11">11</span>
</div>

如何使用 Mechanize 单击跨度？

Answer 1

根据此 ASCIIcasts，您可以执行搜索和发现:

There are two methods on the page object that we can use to extract elements from a page using Nokogiri. The first of these is called at and will return a single element that matches a selector.

agent.page.at(".edit_item")  

The second method is search. This is similar, but returns an array of all of the elements that match.

agent.page.search(".edit_item")

所以做这样的事情:

agent.page.at(".page")

将返回跨度数组。然后您将能够与他们一起工作，只需执行#click 操作即可。

编辑:

只要 span 是一个非交互元素，而 click 是一个 Link Action ，你就必须找到一个解决方法:
