Python Selenium + Datepicker请点击
我一直在努力尝试获取此类房间的价格,例如,通过单击第一个可用的(绿色)datepicker签入输入,然后单击第一个可用的datepicker签入输入,以便生成最短期间的价格。
我的代码很乱,所以如果有人可以发布更简洁的代码来实现这一目标,我将不胜感激。
我正在使用Python selenium + scrapy,尽管以Java为例仍然有用。
更新:
这是代码:
def availability(self, doc): url = doc['url'] + '#calendar'
self.driver.get(url)
is_active = True
# We want to the availability/price for each day in a month.
availabilities = []
# wait for the check in input to load
wait = WebDriverWait(self.driver, 10)
try:
elem = wait.until(
EC.visibility_of_element_located(
(By.CSS_SELECTOR, ".dates-group input[name=startDateInput]")
)
)
except TimeoutException:
pass
else:
elem.click() # open calendar
# wait for datepicker to load
wait.until(
EC.visibility_of_element_located(
(By.CSS_SELECTOR, '.ui-datepicker:not(.loading)'))
)
days = self.driver.find_elements_by_css_selector(
"#ui-datepicker-div tr td"
)
for cell in days:
day = cell.text.strip()
if not day:
continue
if "full-changeover" not in cell.get_attribute("class"):
available = False
else:
available = True
self.logger.warning('CELL "%s"', cell)
self.logger.warning('DAY "%s"', day)
self.logger.warning('available "%s"', available)
# The first iteration was to list the availability, now we want to
# click the first available element to get the price
for cell in days:
day = cell.text.strip()
if not day:
continue
if "full-changeover" in cell.get_attribute("class"):
self.logger.warning('CLICK IT "%s"', day)
self.driver.implicitly_wait(10)
x = self.driver.find_element_by_xpath("//table/tbody/tr/td/a[text()=" + day + "]")
self.driver.implicitly_wait(10)
x.click() # Element not found in the cache issue here
# import ipdb; ipdb.set_trace()
# self.logger.warning('CELL "%s"', cell)
# self.logger.warning('DAY "%s"', day)
# self.logger.warning('available "%s"', available)
# elem.click() # close checkin calendar
# Now lets click on the checkout input to get the price and minimum
# number of days. We probably don't have to wait for the checkout
# because its already loaded but you never know.
try:
elem = wait.until(
EC.visibility_of_element_located(
(By.CSS_SELECTOR,
".dates-group input[name=endDateInput]")
)
)
except TimeoutException:
pass
else:
# elem.click() # open calendar in checkout input
# wait for datepicker to load
wait.until(
EC.visibility_of_element_located(
(By.CSS_SELECTOR, '.ui-datepicker:not(.loading)'))
)
days = self.driver.find_elements_by_css_selector(
"#ui-datepicker-div tr td"
)
for cell in days:
day = cell.text.strip()
if not day:
continue
# This is the first available date to checkout
if "full-changeover" in cell.get_attribute("class"):
self.logger.warning('CLICK IT "%s"', available)
import ipdb; ipdb.set_trace()
# Here we would get the generated price
self.logger.warning('CELL "%s"', cell)
self.logger.warning('DAY "%s"', day)
self.logger.warning('available "%s"', available)
import ipdb; ipdb.set_trace()
return {'availabilities': availabilities, 'is_active': is_active}
谢谢
回答:
关于此日历的一件棘手的事情是,您首先需要将鼠标悬停在特定的日期,然后重新定位活动的日期并单击它。这是一个有效的实现方式,它选择第一个可用的开始和结束日期并打印计算出的价格:
from selenium import webdriverfrom selenium.webdriver import ActionChains
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
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)
driver.close()
目前,它选择20/04/2016
和23/04/2016
并打印180€
。
希望能有所帮助。
