shadow dom 下的陈旧元素异常

如何解决shadow dom 下的陈旧元素异常

我在 shadow DOM 下遇到了陈旧元素的问题，场景如下：

  1. 将鼠标悬停在视频上并显示 Dock，反之亦然

  2. HTML Dom 从不悬停变为悬停，反之亦然：

以下 html 用于不悬停。

<div class="base overlay hidden" style="position:absolute;top:80px;left:139px;height:387px;width:516px;"><div class="downloads"><div class="hide-btn" id="hide-widget">

<ul class="main main-panel">
<li class="panel">
    <span class="select" id="preferred-select" data-selected-value="High">Preferred quality: High</span>
    <a class="download-btn" id="download-main" title="DOWNLOAD">

    </a>
</li>
<li class="message-panel">
    <a class="message" id="showhide-all"></a>

  1. 鼠标悬停后获取元素的代码如下：
public static WebElement getElementFromShadow(String jsPath) {
WebElement element = null
WebDriver driver = DriverFactory.getWebDriver()
JavascriptExecutor jse = ((driver) as JavascriptExecutor)

int attempts = 0;
while (attempts < 5) {
try {
element = ((jse.executeScript('return ' + jsPath)) as WebElement)
if (element != null) {
break;
}
else {
WebDriverWait wait = new WebDriverWait(driver,10,100);
element = wait.until(ExpectedConditions.elementToBeClickable(((jse.executeScript('return ' + jsPath)) as WebElement)))
}
} catch (Exception e) {
e.printStackTrace()
}
attempts++
Thread.sleep(2000)
}

return element
}

但是当运行它时，我得到 org.openqa.selenium.StaleElementReferenceException: stale element reference: stale element not found （会话信息：chrome=91.0.4472.124）

PS：上面的代码在正常的阴影元素上工作正常（没有改变 DOM）。

谁能知道解决问题的任何想法/解决方案，在此先感谢您！
