Ruby 如何从隐藏的选择列表中选择值？

我想从中选择隐藏的选择列表，然后选择选项

0-0,5

我一直收到一个

问题是如何从隐藏的选择列表中选择选项

0-0,5

？我是否应该使用其他东西而不是Watir？

Selenium只允许用户实现交互，因此不允许与隐藏列表交互

如果列表出现在某个操作上（例如鼠标悬停），则需要先执行该操作。如果列表是通过另一个对象（例如select2）显示的，则必须通过该元素进行交互

然而，如果您真的想在不遵循这一点的情况下实现这一点，那么您可以通过selenium执行JavaScript来启用或设置它

这种方法的优点是有争议的，尽管在选择列表后面有一个链接，该链接中有选择列表的向下箭头。单击箭头后，将显示uls和lis。有一个李与你正在寻找的价值。其中有一个链接。点击它

b.select_lists[2].select "0 - 0,5"

b.select_list(:name, 'werkervaring').parent.link.click
b.li(text: '0 - 0,5').link.click

---

注意，为了确保我们使用的是正确的列表，我仍然使用werkervaring作为唯一的定位器，然后在同一个父项下找到了兄弟链接

简短回答：如果用户不能，Selenium不能。用户可以。隐藏的选择列表以某种方式连接到可见的和样式化的列表。看看html。如果我通过可见元素选择

0-0,5

，则隐藏元素也会发生变化并完成所有工作。如果存在可见和样式化元素，为什么不与该元素交互？通过索引定位选择列表不会改变Watir是否可以与之交互。无论您如何找到它，选择列表仍将不可见。因此，Watir/Selenium将不允许您与它进行交互。说您想要的，这对我很有效。我能够操纵表格中的所有内容。

b.select_lists[2].select "0 - 0,5"

b.select_list(:name, 'werkervaring').parent.link.click
b.li(text: '0 - 0,5').link.click
