使用Java Selenium切换标签页时遇数组越界问题求助

核心问题 #

1. 数组越界异常：代码中ArrayList<String> tabs3 = new ArrayList<>(driver.getWindowHandles());在创建新标签页前执行，后续新增标签页、重新初始化ChromeDriver后，tabs3未更新，仍保留旧窗口句柄集合，此时用tabs3.get(2)或tabs3.get(1)访问必然超出集合长度。
2. 标签页无法聚焦：切换窗口时依赖过时的句柄集合，导致WebDriver定位不到目标标签页，无法完成聚焦操作。
3. 冗余操作干扰流程：大量无意义的driver.navigate().forward()调用、固定时长的Thread.sleep会降低代码稳定性，干扰页面加载逻辑。

修复步骤 #

• 动态获取窗口句柄：每次切换标签页前，重新获取当前所有窗口句柄，不依赖提前保存的旧集合。
• 统一Driver实例：避免中途替换Driver对象，否则原Driver的窗口句柄会完全失效，用单个Driver完成全流程操作。
• 替换固定等待为显式等待：用WebDriverWait等待元素可交互，替代不稳定的Thread.sleep。
• 移除无效页面操作：删除无意义的forward()调用，仅在需要前进页面时使用。
