Selenium遍历日期选择器选可用日期及预约时间解决方案

我正在编写脚本，用Selenium操作日期选择器预约业务。可用日期显示为绿色，但无法通过class、title这类属性直接定位（不确定其出现时机）。选中可用日期后，会触发原本隐藏的预约时间和签证类型下拉列表。需解决两个核心问题：

• 遍历所有日期，找到第一个可用日期并选中
• 遍历预约时间，找到第一个可用时段并选中

当前已有部分代码：

from selenium.webdriver.common.by import By 
from selenium.webdriver.support.ui import WebDriverWait 
from selenium.webdriver.support import expected_conditions as ec 
import sys 

available_dates = driver.find_elements(By.XPATH, "//div[@class='datepicker-days']/table/tbody/tr/td[not(contains(@class, 'disabled'))]") 

for date in available_dates:
 print(date.text)

可用日期HTML示例：

<td class="day activeClass" title="Book">23</td>

1. 定位并选中可用日期 #

由于可用日期出现时机不确定，必须用显式等待轮询加载，同时加入月份切换逻辑处理当前月无可用日期的情况：

# 等待日期选择器加载完成
datepicker = WebDriverWait(driver, 10).until(
    ec.presence_of_element_located((By.CLASS_NAME, "datepicker-days"))
)

found_available_date = False
while not found_available_date:
    # 获取所有非禁用的日期，优先匹配带activeClass的元素
    available_dates = driver.find_elements(By.XPATH, "//div[@class='datepicker-days']/table/tbody/tr/td[not(contains(@class, 'disabled')) and contains(@class, 'day')]")
    
    if available_dates:
        # 优先选择标记为activeClass的可用日期
        for date in available_dates:
            if "activeClass" in date.get_attribute("class"):
                # 用JS点击避免元素不可交互问题
                driver.execute_script("arguments[0].click();", date)
                print(f"已选中可用日期: {date.text}")
                found_available_date = True
                break
        # 若无activeClass标记，选择第一个非禁用日期
        if not found_available_date:
            driver.execute_script("arguments[0].click();", available_dates[0])
            print(f"已选中可用日期: {available_dates[0].text}")
            found_available_date = True
    else:
        # 切换到下一月（需根据实际页面调整下一月按钮的定位器）
        try:
            next_month_btn = driver.find_element(By.XPATH, "//th[@class='next']")
            next_month_btn.click()
            # 等待月份切换完成
            WebDriverWait(driver, 5).until(ec.staleness_of(datepicker))
            datepicker = WebDriverWait(driver, 10).until(ec.presence_of_element_located((By.CLASS_NAME, "datepicker-days")))
        except Exception:
            print("已无更多月份可切换，未找到可用日期")
            sys.exit(1)

2. 定位并选中可用预约时段 #

选中日期后，预约时间下拉列表会从隐藏变为可见，同样用显式等待确保元素加载完成：

try:
    # 等待预约时间下拉列表可见（替换为实际页面的元素定位器）
    time_dropdown = WebDriverWait(driver, 10).until(
        ec.visibility_of_element_located((By.XPATH, "//select[@id='appointment-time']"))
    )
    # 获取所有非禁用的时段选项
    available_times = time_dropdown.find_elements(By.XPATH, "./option[not(@disabled)]")
    
    if available_times:
        available_times[0].click()
        print(f"已选中可用时段: {available_times[0].text}")
    else:
        print("当前日期无可用预约时段")
        sys.exit(1)
except Exception as e:
    print(f"加载预约时段失败: {str(e)}")
    sys.exit(1)

            next_month_btn.click()

        except Exception:
            print("未找到可用日期，已无更多月份可切换")
            sys.exit(1)

# --- 处理预约时段选择 ---
try:
    time_dropdown = WebDriverWait(driver, 10).until(
        ec.visibility_of_element_located((By.XPATH, "//select[@name='appointment-time']"))
    )
    available_times = time_dropdown.find_elements(By.XPATH, "./option[not(@disabled)]")
    if available_times:
        available_times[0].click()
        print(f"已选中可用时段: {available_times[0].text}")
    else:
        print("当前日期无可用预约时段")
        sys.exit(1)

关键说明 #

• 用WebDriverWait显式等待替代直接查找，彻底解决元素加载时机不确定的问题
• 采用driver.execute_script点击日期，规避元素被遮挡、不可交互的常见问题
• 加入月份切换逻辑，覆盖当前月无可用日期的场景
• 优先匹配activeClass标记的日期，完全贴合提供的HTML结构
