我无法解决这个问题，有人可以帮助我吗？ "'NoneType' object has no attribute 'send_keys'"

Question

问题是如何使用send_keys？因为它没有写在搜索栏中。

我在文件中搜索，但无法解决。

from selenium import webdriver 
from selenium.webdriver.support.ui import WebDriverWait 
from selenium.webdriver.support import expected_conditions as EC 
from selenium.webdriver.common.keys import Keys 
from selenium.webdriver.common.by import By 
import time 
# Open Chrome
driver = webdriver.Chrome('C:/xampp/htdocs/pegasus/chromedriver') 
# Going to website
driver.get("https://www.flypgs.com/en")
# Select button by class name and click on it.
frombtn = driver.find_element_by_class_name('select2-selection').click()
searchbtn = driver.find_element_by_class_name("select2-search__field").click()
# ERROR is here below on send_keys.
searchbtn.send_keys('Amsterdam')
time.sleep(1000000)

给出的错误是：

Exception has occurred: AttributeError
'NoneType' object has no attribute 'send_keys'
File "C:xampphtdocspegasusapp.py", line 17, in <module>
searchbtn.send_keys('Amsterdam')

Answer 1

您为searchbtn分配了错误的值

您正在分析click()返回的值，该值始终为None

你必须分两步完成

searchbtn = driver.find_element_by_class_name("select2-search__field")
searchbtn.click()

然后searchbtn是正确的，您可以使用send_key()

更改代码后工作

from selenium import webdriver 
from selenium.webdriver.support.ui import WebDriverWait 
from selenium.webdriver.support import expected_conditions as EC 
from selenium.webdriver.common.keys import Keys 
from selenium.webdriver.common.by import By 
import time 
driver = webdriver.Chrome('C:/xampp/htdocs/pegasus/chromedriver') 
driver.get("https://www.flypgs.com/en")
frombtn = driver.find_element_by_class_name('select2-selection')
frombtn.click()
searchbtn = driver.find_element_by_class_name("select2-search__field")
searchbtn.click()
searchbtn.send_keys('Amsterdam')
time.sleep(1000000)
