Java 再次过时的元素引用：元素未附加到页面文档

当你在做

driver.findElement(completeButtonByXpath);

现在selenium正在寻找*//button[text()='Complete']个xPath.

可能在这个时候，它没有连接到HTML-DOM和staleness.

Solution:

1. 一个非常简单的解决方案是将硬编码睡眠如下:

   Thread.sleep(5000);
   

现在找WebElement completeButton = driver.findElement(completeButtonByXpath);个

2. 将completeSession修改为只进行显式等待.

   public void completeSession() {
    By completeButtonByXpath = By.xpath("*//button[text()='Complete']");
    //WebElement completeButton = driver.findElement(completeButtonByXpath);
    WebDriverWait wait = new WebDriverWait(driver, 30);
    wait.until(ExpectedConditions.elementToBeClickable(completeButtonByXpath)).click();
   }
   

3. 重试clicking次.

Code:

public void completeSession() {
    By completeButtonByXpath = By.xpath("*//button[text()='Complete']");
    WebElement completeButton = driver.findElement(completeButtonByXpath);
    int attempts = 0;
    while(attempts < 5) {
        try {
            completeButton.click();
            break;
        }
        catch(StaleElementReferenceException staleException) {
            staleException.printStackTrace();
        }
        attempts++;
    }
}
