Question

我一直试图找到一种方法来确认光标位于输入字段内（模拟在该字段内点击）。

如果字段条目验证失败，则会在网页顶部调用错误消息。

错误消息是一个超链接，当按下该按钮时，滚动指向该输入字段所在的页面，并将光标放在该字段中。

有没有办法确认光标在框中？

当光标位于文本字段中时，表示文本字段处于焦点或是活动元素。 Capybara没有直接为此提供方法。但是，有几种选择。

切换到有效元素

如果您下拉到底层的Selenium驱动程序，则可以检索活动元素：

使用活动元素，您可以检查它是否是您期望的元素：

string pdfFolder;

#if DEBUG
            DirectoryInfo directoryInfo = Directory.GetParent(Directory.GetParent(Environment.CurrentDirectory).FullName);
            pdfFolder = directoryInfo.FullName + @"\PdfFile\Auto Refill Reminder List.pdf";
            System.Diagnostics.Process.Start(pdfFolder );
#endif

#if (!DEBUG)
            pdfFolder = Environment.CurrentDirectory + @"\PdfFile\Auto Refill Reminder List.pdf";
            Process.Start(pdfFolder);
#endif

使用page.driver.browser.switch_to.active_element => #<Selenium::WebDriver::Element:0x34409cfc id="0.6429182184051125-3">

另一种方法是使用JavaScript获取有关活动元素的一些细节。例如，以下内容返回焦点元素的id：

# Use Capybara to find the element you expect to be in focus
expected_element = page.find("#field_id")

# Get the element that is actually in focus
active_element = page.driver.browser.switch_to.active_element

# Check that the two elements are the same
# Note that you need to call `native` so that you are comparing Selenium elements
expect(active_element).to eq(expected_element)

Selenium确认光标的位置
