如何获得WebElement的父级 [英] How to get parent of WebElement

问题描述

我已经尝试了

private WebElement getParent(final WebElement webElement) {
    return webElement.findElement(By.xpath(".."));
}

但我得到：

org.openqa.selenium.InvalidSelectorException：给定的选择器..
无效或者不会产生WebElement。出现以下错误
：
InvalidSelectorError：xpath表达式的结果
" .."是：[对象XrayWrapper [对象HTMLDocument]]。它
应该是一个元素。
命令持续时间或超时：10
毫秒
有关此错误的文档，

org.openqa.selenium.InvalidSelectorException: The given selector .. is either invalid or does not result in a WebElement. The following error occurred: InvalidSelectorError: The result of the xpath expression ".." is: [object XrayWrapper [object HTMLDocument]]. It should be an element. Command duration or timeout: 10 milliseconds For documentation on this error,

有没有办法获取当前元素的父元素？谢谢

推荐答案

有几种方法可以实现这一目标。如果您坚持使用XPath来执行此操作，则需要将上下文节点添加到定位器，如下所示：

There are a couple of ways you can accomplish this. If you insist on using XPath to do it, you need to add the context node to the locator, like this:

WebElement parentElement = childElement.findElement(By.xpath("./.."));

或者，您可以使用 JavascriptExecutor 界面，可能稍微高效一点。这看起来像这样：

Alternatively, you can use the JavascriptExecutor interface, which might be slightly more performant. That would look like this:

// NOTE: broken into separate statements for clarity. Could be done as one statement.
JavascriptExecutor executor = (JavascriptExecutor)driver;
WebElement parentElement = (WebElement)executor.executeScript("return arguments[0].parentNode;", childElement);
