使用Watir访问订单列表中的列表项的元素 [英] Accessing elements of list items within an order list using Watir

问题描述

我尝试点击订单商品列表中的链接。 $ b

该列表是观看次数最多的视频的顺序。

我只是想选择第一个列表项目，所以浏览器将导航到href。

现在，我有

  $ website.element（： gs-c-promo-heading nw-o-link gs-o-bullet__text gs-o-faux-block-link__overlay-link gel-pica-bold gs-u-pl @ xs）。click 
  

与另一行代码类似，我必须选择最上面的故事，效果很好。任何想法，为什么这是行不通的？

另外，我将如何抓住这个有序的列表中的所有项目，并打印出每个链接文本？

解决方案

我无法重现您的例外情况。然而，考虑到例外情况，答案将是去除复合类的名称 - 即在类定位符中不能有任何空格。

大多数类看起来都是通用的，所以可能会被删除。您可以尝试：

  $ website.element（：class =>gs-c-promo-heading）。 
  

如果类真的很重要，可以使用Watir的新多类定位器。这会构建一个大的XPath，它不会触发Selenium的复合类检查器。

  $ website.element（：class => [ gs-c-promo-heading，nw-o-link，gs-o-bullet__text，gs-o-faux-block-link__overlay-link，gel-pica-bold，gs点击
  

要获取所有项目，我会找到 li 元素基于它们的 data-entityid 属性，它看起来是描述性的：

  $ website.lis（data_entityid：/most-popular-watched/).each do | li | 
 puts li.link.text 
 end 
  

这也可能是更多描述性地点击第一个链接：

  $ website.li（data_entityid：/most-popular-watched/).link。点击
  

I am trying to click a link that is within a list of ordered items.

The list is a order of most watched videos.

I'm just trying to select the first list item, so that the broswer will navigate to the href.

Right now, i have

$website.element(:class => "gs-c-promo-heading nw-o-link gs-o-bullet__text gs-o-faux-block-link__overlay-link gel-pica-bold gs-u-pl@xs").click

Which is similar to another line of code i have to select the top story, works fine. Any ideas why this isn't working?

Also, how would i grab all the items in this ordered list and print out each link text?

解决方案

I was not able to reproduce your exception. However, given the exception, the answer would be to remove the compound class name - ie you cannot have any spaces in the class locator.

Most of the classes seem generic, so could likely be removed. You could try:

$website.element(:class => "gs-c-promo-heading").click

If the classes really are important, you can use Watir's new multi-class locator. This builds a large XPath, which would not trigger Selenium's compound class checker.

$website.element(:class => ["gs-c-promo-heading", "nw-o-link", "gs-o-bullet__text", "gs-o-faux-block-link__overlay-link", "gel-pica-bold", "gs-u-pl@xs"]).click    

To grab all of the items, I would locate the li elements based on their data-entityid attribute which looks descriptive:

$website.lis(data_entityid: /most-popular-watched/).each do |li|
  puts li.link.text
end

This might also be a more descriptive way to click the first link:

$website.li(data_entityid: /most-popular-watched/).link.click
