如何获得在Capybara的父节点？ [英] How to get parent node in Capybara?

问题描述

我正在使用许多jQuery插件，通常创建没有id或其他标识属性的DOM元素，并获得他们在Capybara（例如点击）的唯一方法是获取他们的邻居祖先）。但是我没有找到任何地方，Capybara支持这样的事情例如：

I'm working with many jQuery plugins, that often create DOM elements without id or other identification properties, and the only way to get them in Capybara (for clicking for example) - is to get their neighbor (another child of its ancestor) first. But I didn't find anywhere, does Capybara support such things for example:

find('#some_button').parent.fill_in "Name:", :with => name

？

推荐答案

我真的发现jamuraa的答案有帮助，但是完整的xpath给了我一个噩梦的字符串在我的情况下，所以我很高兴地利用了连接的水平Capybara的能力，让我混合css和xpath选择。您的示例将如下所示：

I really found jamuraa's answer helpful, but going for full xpath gave me a nightmare of a string in my case, so I happily made use of the ability to concatenate find's in Capybara, allowing me to mix css and xpath selection. Your example would then look like this:

find('#some_button').find(:xpath,".//..").fill_in "Name:", :with => name

Capybara 2.0更新： find xpath，// ..）将很可能导致模糊匹配错误。在这种情况下，改用 first（：xpath，.// ..）。

Capybara 2.0 update: find(:xpath,".//..") will most likely result in an Ambiguous match error. In that case, use first(:xpath,".//..") instead.
