Question

from selenium import webdriver
from selenium.common.exceptions import TimeoutException
from selenium.webdriver.common.by import By
from selenium.webdriver.support import expected_conditions as EC 
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.support.wait import WebDriverWait

mylist=[]
my_category=""

driver=webdriver.Chrome("C:\\Python27\\selenium\\webdriver\\chrome\\chromedriver.exe")

driver.get('http://booking.com')

driver.find_element_by_css_selector("#ss").send_keys("Rhodes, Greece")
WebDriverWait(driver, 5)

driver.find_element_by_css_selector("button.sb-searchbox__button").submit()

category = driver.find_elements_by_css_selector("span.sr-hotel__name")

wait = WebDriverWait(driver, 10)

while True:
    wait.until(EC.element_to_be_clickable((By.CLASS_NAME, '.paging-next')))
    try:
        for link in category:
            my_category = link.text
            print (my_category)
            mylist.append(my_category)
            element=wait.until(EC.visibility_of_element_located((By.LINK_TEXT, 'Next page')))
            element.click()
    except TimeoutException:
            break

这是我收到的错误消息：

Answer 1

您应该通过CLASS_NAME和CSS_SELECTOR区分搜索中的班级名称使用情况：

假设我们有<a class="paging-next">

如果使用By.CLASS_NAME来定位元素，则应将其用作

wait.until(EC.element_to_be_clickable((By.CLASS_NAME, 'paging-next')))

请注意，在课名（'paging-next'）之前没有点

如果使用By.CSS_SELECTOR来定位元素，则应将其用作

wait.until(EC.element_to_be_clickable((By.CSS_SELECTOR, '.paging-next')))

请注意，在课名（'.paging-next'）之前是一个点

尝试在python阵列中添加来自booking.com的酒店名称，同时自动点击下一页
