我们可以使用 Selenium webdriver 获取 HTML 表格中每个单元格的文本。`

` 标签用于在 html 文档中定义表格。表格由 `` 表示的行和 `

` 表示的列组成。表头由 `	` 标签标识。让我们考虑一个表格，我们将从中获取每个单元格的文本。自动化工具类型链接Selenium开源https://www.selenium.org/UFT商业统一功能测试Ranorex商业https://www.ranorex.com/TestComplete商业Test Coomplete让我们看看上面表格的 html 代码表示 -

更新于 2020年9月18日 08:06:50 17000+ 次浏览我们可以使用 Selenium webdriver 获取文本框中输入的文本。要获取 html 文档中元素的 value 属性，我们必须使用 getAttribute() 方法。然后将 value 值作为参数传递给该方法。让我们考虑一个文本框，我们在其中输入了一些文本，然后想要获取输入的文本。如果我们侦测该元素，我们会发现 html 代码中此元素没有 value 属性。在该字段中输入文本后，我们可以使用 getAttribute() 方法获取输入的文本。示例 import org.openqa.selenium.By; import org.openqa.selenium.WebDriver; import org.openqa.selenium.WebElement; ... 阅读更多使用 Python 和 Selenium
