消息：陳舊元素引用：元素未附加到頁面文檔PYTHON硒

Question

我正在嘗試從網站獲取劇集鏈接。 所以我需要輸入鏈接並從情節中獲取信息。 它以2-3集的形式工作，然后崩潰，並在底部產生錯誤。 我試圖增加睡眠時間，但它仍然崩潰。

錯誤：

selenium.common.exceptions.StaleElementReferenceException: Message: stale element reference: element is not attached to the page document

Answer 1

當元素未附加到DOM時，將發生陳舊的元素異常。 過期的元素異常后，嘗試再次查找該元素。

考慮單擊元素將刷新頁面。
例：

 WebElement element = driver.findElement(By.Id("refreshButton"));
 element.Click(); //page will be refreshed after clicking this button
 element.Click(); //stale element exception will throw

現在，如果您對該元素執行任何操作（單擊，senkeys等），它將拋出StaleElementException，因為它丟失了引用（頁面已刷新）

為了解決這個問題，請在頁面刷新后再次找到該元素。

 WebElement element = driver.findElement(By.Id("refreshButton"));
 element.Click(); //page will be refreshed after clicking this button

 element = driver.findElement(By.Id("refreshButton"));
 element.Click();
