无法发送密钥 selenium webdriver python

Question

Trying to execute simple test

from selenium import webdriver
from selenium.webdriver.common.keys import Keys

driver = webdriver.Firefox()

driver.get('http://google.com')
driver.find_element_by_name('q')
driver.send_keys('hey')

And getting the error

Traceback (most recent call last):
  File "C:/webdriver/test.py", line 8, in <module>
    driver.send_keys('hey')
AttributeError: 'WebDriver' object has no attribute 'send_keys'

What's the problem?

Answer 1

WebDriver instance does not have send_keys() method . That's what the error is actually about:

'WebDriver' object has no attribute 'send_keys'

Call send_keys() on a WebElement instance which is returned by find_element_by_*() methods - find_element_by_name() in your case:

element = driver.find_element_by_name('q')
element.send_keys("hey")

---

And just FYI, there is also an ActionChains class which is useful do build up chains of actions or apply more complex actions like drag&drop or mouse move. It's an overhead in this case, but just for the sake of an example:

from selenium.webdriver.common.action_chains import ActionChains

actions = ActionChains(driver)
actions.move_to_element(element).send_keys("hey").perform()

Answer 2

You must change the reference element

driver.get('http://google.com')
elem.find_element_by_name('q')
elem.send_keys('hey')

Answer 3

Did you try changing your reference element. It would be a good practice if you call webdriver using different reference. Your code after changing reference.

from selenium import webdriver
from selenium.webdriver.common.keys import Keys
import time

driver = webdriver.Firefox()
driver.get('http://google.com')
#Firefox Webdriver is created and navigated to google.

elem = driver.find_element_by_name('q')
elem.send_keys('hey',Keys.RETURN)
#Keys.RETURN = Pressing Enter key on keyboard

time.sleep(5)
driver.close()

Answer 4

I had faced same issue, but I got solution for that.

Use move_to_element in ActionChains .

1. Find element. elem = driver.find_element_by_*

2. create your actionchain driver actions = ActionChains(driver)

3. use move to command, so webdriver will point to that element's position, but before you send key, you need to set webdriver position on that element by using click() function. Now, webdriver has a surface area to place given keys (data) and for that you will use send_keys() function. In the last just put perform() function to execute these all task very smoothly. actions.move_to_element(<ELEMENT>).click().send_keys(<DATA>).perform()

   https://selenium-python.readthedocs.io/api.htmlt

from selenium import webdriver
from selenium.webdriver.common.keys import Keys

driver = webdriver.Firefox()

driver.get('http://google.com')
elem = driver.find_element_by_name('q')
actions = ActionChains(driver)
actions.move_to_element(elem).click().send_keys('hey').perform()

Answer 5

The problem with your code is you have not tell driver where to send the keys 

    from selenium import webdriver
    from selenium.webdriver.common.keys import Keys
    
    driver = webdriver.Firefox()
    
    driver.get('http://google.com')
    driver.find_element_by_name('q')
    driver.send_keys('hey') // driver dont know where to send the keys

correct code would be :

from selenium import webdriver
from selenium.webdriver.common.keys import Keys

driver = webdriver.Firefox()

driver.get('http://google.com')
goog = driver.find_element_by_name('q') // you have stored element in goog variable
goog.send_keys('hey') // you told variable to send hey 

or 

you can directly send after finding the element like :

from selenium import webdriver
from selenium.webdriver.common.keys import Keys

driver = webdriver.Firefox()

driver.get('http://google.com')
driver.find_element_by_name('q').send_keys('hey')

If it helps so please accept the answer !!

Answer 6

Its with the version of selenium which is causing the issue. I faced the same issue.

Its with the selenium version 3.3.3 which has the compatibility problem.

Try: pip uninstall selenium pip install selenium==3.3.1

Hope it works.
