Selenium Java日期选择器点击下一页仅一次生效报element not interactable异常求解

根因分析 #

• 循环逻辑错误：切换月份、年份的两个while循环末尾都加了break语句，导致循环仅执行1次就强制退出，无法连续切换多个月份/年份
• 点击目标错误：直接点击下一页按钮的子元素span，实际可交互的是外层的<a>标签，容易触发交互失效
• 缺少显式等待：每次点击下一页后日期选择器DOM会重新渲染，未等待元素就绪就执行下一步，导致元素还未加载完成就触发点击操作
• 逻辑顺序错误：先切换月份再切换年份，逻辑倒置，应该优先匹配年份再匹配月份，避免跨年度切换时逻辑错误
• 陈旧元素问题：点击下一页后原DOM节点失效，未重新定位元素直接操作会触发交互异常

修复要点 #

• 移除while循环里的break语句，保证循环能连续执行直到匹配到目标年月
• 点击目标改为下一页按钮的外层<a>标签，提高交互稳定性
• 每次点击下一页前添加显式等待，保证元素处于可点击状态
• 调整逻辑顺序，先匹配年份再匹配月份
• 每次获取月份、年份前重新定位对应元素，避免陈旧元素异常
