从日期选择器获取可用性

Question

我正在尝试通过单击日期选择器日历中的下一步按钮来获取 homeaway 中每一天的价格，但没有成功。

我当前的代码是这样的：

def handle(self, *args, **options):
    def homeaway(self):
        display = Display(visible=0, size=(1024, 768))
        display.start()
        driver = webdriver.Firefox()
        driver.maximize_window()

        wait = WebDriverWait(driver, 10)

        url = 'https://www.homeaway.pt/arrendamento-ferias/p1418427a?uni_id=1590648'
        driver.get(url)

        # pick start date
        start_date = wait.until(EC.visibility_of_element_located((
                                                                 By.CSS_SELECTOR,
                                                                 ".quotebar-container input[name=startDateInput]")))
        start_date.click()

        first_available_date = wait.until(EC.element_to_be_clickable(
            (By.CSS_SELECTOR, "#ui-datepicker-div td.full-changeover > a")))
        ActionChains(driver).move_to_element(first_available_date).perform()
        driver.find_element_by_css_selector(
            "#ui-datepicker-div td.full-selected.full-changeover > a").click()

        # pick end date (TODO: violates DRY principle, refactor!)
        end_date = wait.until(EC.visibility_of_element_located(
            (By.CSS_SELECTOR, ".quotebar-container input[name=endDateInput]")))
        end_date.click()

        first_available_date = wait.until(EC.element_to_be_clickable(
            (By.CSS_SELECTOR, "#ui-datepicker-div td.full-changeover > a")))
        ActionChains(driver).move_to_element(first_available_date).perform()
        driver.find_element_by_css_selector(
            "#ui-datepicker-div td.full-selected.full-changeover > a").click()

        # get the calculated price
        price = wait.until(EC.visibility_of_element_located(
            (By.CSS_SELECTOR, ".price-quote .price-total")))

        print(price.text.encode('ascii', 'ignore'))

        driver.close()

他们都工作，但只有 1 个月。我希望能够设置 X 个月。例如对于homeaway，我在第一次打开日历点击后尝试使用self.driver.find_element_by_css_selector('.ui-datepicker-next.ui-corner-all').c‌​lick()，但我得到了ElementNotVisibleException

提前致谢

Answer 1

要在日期选择器已打开时单击“下个月”按钮，请尝试以下操作：

def click_next_month(self):
    elements = self.driver.find_element_by_xpath('//span[@class="ui-icon ui-icon-circle-triangle-e"]')
    elements[1].click()

要多次单击“下个月”按钮，您需要每次重新定义elements，因此最好将这两个操作（定义列表和按钮单击）实现为方法click_next_month()。

如果出现任何问题，请尝试告诉我

我能够使用 driver.execute_script('$( "a.ui-datepicker-next" ).click()') 来完成这项工作，因为其他所有东西都给了我 ElementNotVisibleException 然后我注意到其中涉及到 javascript

<a class="ui-datepicker-next ui-corner-all" data-handler="next" data-event="click" title="Próximo>"><span class="ui-icon ui-icon-circle-triangle-e">Próximo&gt;</span></a>

我宁愿不直接使用Javascript 或jQuery，所以如果有人有更好的建议，我可以试试。

但仍有一些怪癖，例如，每次我获得某个月份的可用性时，我都必须手动重置日历。

这是我的最终代码：

def homeaway(self):
    MONTH_COUNT = 6
    display = Display(visible=0, size=(1024, 768))
    display.start()
    driver = webdriver.Firefox()
    driver.maximize_window()

    wait = WebDriverWait(driver, 10)

    url = 'https://www.homeaway.pt/arrendamento-ferias/p1418427a?uni_id=1590648'
    driver.get(url)

    count = 0
    for month in range(MONTH_COUNT):
        # pick start date
        start_date = wait.until(EC.visibility_of_element_located((
            By.CSS_SELECTOR,
            ".quotebar-container input[name=startDateInput]")))
        start_date.click()

        for x in range(count):
            driver.execute_script('$( "a.ui-datepicker-next" ).click()')

        current_month = driver.find_element_by_css_selector(
            ".ui-datepicker-month").text

        print("current_month:", current_month)

        first_available_date = wait.until(EC.element_to_be_clickable(
            (By.CSS_SELECTOR, "#ui-datepicker-div td.full-changeover > a")))

        ActionChains(driver).move_to_element(first_available_date).perform()
        driver.find_element_by_css_selector(
            "#ui-datepicker-div td.full-selected.full-changeover > a").click()

        # pick end date (TODO: violates DRY principle, refactor!)
        end_date = wait.until(EC.visibility_of_element_located(
            (By.CSS_SELECTOR,
             ".quotebar-container input[name=endDateInput]")))

        end_date.click()

        first_available_date = wait.until(EC.element_to_be_clickable(
            (By.CSS_SELECTOR, "#ui-datepicker-div td.full-changeover > a")))

        ActionChains(driver).move_to_element(first_available_date).perform()
        driver.find_element_by_css_selector(
            "#ui-datepicker-div td.full-selected.full-changeover > a").click()

        # get the calculated price
        price = wait.until(EC.visibility_of_element_located(
            (By.CSS_SELECTOR, ".price-quote .price-total")))

        print(price.text.encode('ascii', 'ignore'))

        driver.execute_script('$( "button.ui-datepicker-clear" ).click()')

        count += 1

    driver.close()
