How to get parent of WebElement
提问by Jae
I've tried
我试过了
private WebElement getParent(final WebElement webElement) {
return webElement.findElement(By.xpath(".."));
}
But I'm getting:
但我得到：
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,
org.openqa.selenium.InvalidSelectorException：给定的选择器 .. 无效或不会导致 WebElement。发生以下错误：InvalidSelectorError：xpath 表达式“..”的结果是：[object XrayWrapper [object 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，
Is there a way to get the parent of current element? Thanks

Alternatively, can you try using Javascript Executor?
或者，您可以尝试使用 Javascript Executor 吗？
WebElement childElement = driver.findElement(By.id("someIdHere"));
WebElement parent = (childElement) ((JavascriptExecutor) driver)
.executeScript("return arguments[0].parentNode;", childElement);

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:
有几种方法可以实现这一点。如果坚持使用 XPath 来做，则需要将上下文节点添加到定位器中，如下所示：
WebElement parentElement = childElement.findElement(By.xpath("./.."));
Alternatively, you can use the JavascriptExecutorinterface, which might be slightly more performant. That would look like this:
或者，您可以使用该JavascriptExecutor界面，它的性能可能稍高一些。那看起来像这样：
// 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);
