Makemytrip网站出发日期点击失败，抛出Selenium超时异常求助

问题场景 #

使用Selenium自动化操作Makemytrip网站时，尝试点击出发日期字段中的特定日期，程序持续抛出异常，核心错误为找不到指定元素。

错误信息 #

解决方案 #

• 优化元素定位器：Makemytrip页面元素的class属性（如inactiveWidget）可能随页面状态动态变化，避免依赖完整静态class值。改用更稳定的XPath定位：

  //span[contains(text(), 'Departure')]/ancestor::div[contains(@class, 'flt_fsw_inputBox')]
  

• 等待元素可交互：替换presenceOfElementLocated()为elementToBeClickable()，确保元素不仅存在且可点击：

  WebDriverWait wait = new WebDriverWait(driver, Duration.ofSeconds(20));
  WebElement departureField = wait.until(ExpectedConditions.elementToBeClickable(By.xpath("//span[contains(text(), 'Departure')]")));
  departureField.click();
  

• 处理页面弹窗：首页的广告弹窗会遮挡目标元素，需先定位并关闭弹窗再操作日期栏。
• 匹配ChromeDriver版本：当前Chrome浏览器版本为121.0.6167.85，但ChromeDriver版本为120.0.6099.109，版本不匹配会导致元素定位异常，需更新ChromeDriver至对应版本。
• 避免等待方式混用：不要同时使用隐式等待和显式等待，确保等待逻辑仅针对目标元素，避免冲突。
