我一直在討論如何使用selenium自動(dòng)化陰影DOM元素？使用#shadow-root (open)元素。在通過(guò)Selenium訪問(wèn)URL時(shí)出現(xiàn)Clear data的清除瀏覽數(shù)據(jù)彈出窗口中找到按鈕的過(guò)程中，我無(wú)法找到以下元素：chrome://settings/clearBrowserData#shadow-root (open)<settings-privacy-page>快照：設(shè)置 - 隱私頁(yè)使用Selenium以下是我的代碼試驗(yàn)和遇到的相關(guān)錯(cuò)誤：嘗試1：WebElement root5 = shadow_root4.findElement(By.tagName("settings-privacy-page"));錯(cuò)誤：Exception in thread "main" org.openqa.selenium.JavascriptException: javascript error: b.getElementsByTagName is not a function嘗試2：WebElement root5 = shadow_root4.findElement(By.cssSelector("settings-privacy-page"));錯(cuò)誤：Exception in thread "main" org.openqa.selenium.NoSuchElementException: no such element: Unable to locate element: {"method":"css selector","selector":"settings-privacy-page"}嘗試3：WebElement root5 = (WebElement)((JavascriptExecutor)shadow_root4).executeScript("return document.getElementsByTagName('settings-privacy-page')[0]");錯(cuò)誤：Exception in thread "main" java.lang.ClassCastException: org.openqa.selenium.remote.RemoteWebElement cannot be cast to org.openqa.selenium.JavascriptExecutor如果它有用，初始代碼塊（直到上面的行）完美運(yùn)行：driver.get("chrome://settings/clearBrowserData");WebElement root1 = driver.findElement(By.tagName("settings-ui"));WebElement shadow_root1 = expand_shadow_element(root1);WebElement root2 = shadow_root1.findElement(By.cssSelector("settings-main#main"));WebElement shadow_root2 = expand_shadow_element(root2);WebElement root3 = shadow_root2.findElement(By.cssSelector("settings-basic-page[role='main']"));WebElement shadow_root3 = expand_shadow_element(root3);WebElement root4 = shadow_root3.findElement(By.cssSelector("settings-section[page-title='Privacy and security']"));WebElement shadow_root4 = expand_shadow_element(root4);PS：expand_shadow_element()工作完美無(wú)瑕。有人可以幫幫我嗎？

然而，由于所需的元素從打開陰影DOM需要引起WebDriverWait的elementToBeClickable()，你可以在你的解決方案如下：
代碼塊：
driver.get("chrome://settings/clearBrowserData");
new WebDriverWait(driver, 5).until(ExpectedConditions.elementToBeClickable((WebElement) ((JavascriptExecutor)driver).executeScript("return document.querySelector('settings-ui').shadowRoot.querySelector('settings-main').shadowRoot.querySelector('settings-basic-page').shadowRoot.querySelector('settings-section > settings-privacy-page').shadowRoot.querySelector('settings-clear-browsing-data-dialog').shadowRoot.querySelector('#clearBrowsingDataDialog').querySelector('#clearBrowsingDataConfirm')"))).click();
System.out.println("Clear data Button Clicked");
控制臺(tái)輸出：
Clear data Button Clicked
