python - 类型错误 : 'WebElement' object is not iterable

Question

我在这里缺少什么？该脚本将像第一个配置文件一样单击，但下一个配置文件将失败。

import time
from selenium.webdriver import Chrome
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.chrome.options import Options

driver = Chrome()
driver.get('https://www.okcupid.com/login')
redirect = ('https://www.okcupid.com/doubletake')

username = driver.find_element_by_name('username')
password = driver.find_element_by_name("password")

username.send_keys("gmail.com")
password.send_keys("password")
#driver.find_element_by_xpath("//input[@class='login2017-actions-button']").click()
driver.find_element_by_class_name('login2017-actions-button').click()
time.sleep(5)
driver.get(redirect)

hoes = driver.find_element_by_xpath("//button[@class='cardactions-action cardactions-action--like']")

while 1:
    print('Liking')
    hoes.click()
    time.sleep(5)

但是当我进行这些更改时，它根本不起作用:

hoes = driver.find_elements_by_xpath("//button[@class='cardactions-action cardactions-action--like']")

for matches in hoes:
    print('Liking')
    hoes.click()
    time.sleep(5)

Liking
Traceback (most recent call last):
File "/home/cha0zz/Desktop/scripts/okcupid.py", line 24, in <module>
hoes.click()
AttributeError: 'list' object has no attribute 'click'


Answer 1

这里

hoes = driver.find_element_by_xpath("//button[@class='cardactions-action cardactions-action--like']")

while 1:
    print('Liking')
    hoes.click()

find_element_by_xpath 返回单个对象。这意味着您可以为其调用 click (当然，如果找到该元素)，但您无法迭代 - 单个元素不是列表，并且没有定义的 __iter__ 成员.

在您的其他示例代码中

hoes = driver.find_elements_by_xpath("//button[@class='cardactions-action cardactions-action--like']")

for matches in hoes:
    print('Liking')
    hoes.click()
    time.sleep(5)

hoes 现在是一个列表，因此您无法单击它，但可以迭代。也许您想点击 hoes 的每个成员，您可以通过一个小修复 hoes.click() => match.click():

hoes = driver.find_elements_by_xpath("//button[@class='cardactions-action cardactions-action--like']")

for matches in hoes:
    print('Liking')
    matches.click()
    time.sleep(5)
