python selenium无法清除输入字段

Question

我尝试使用 selenium 选择我的输入，但是当我使用它时它不起作用：

driver = self.driver
password = driver.find_element_by_xpath("//input[@name='password']")
password.clear()
password.send_keys(password)
password.send_keys(Keys.RETURN)

# the sentence below doesn't work
password.send_keys(Keys.COMMAND, 'a')
password.send_keys(Keys.DELETE)

我使用的是 Mac，所以 Keys.CONTROL 不起作用，谁能帮助我如何选择输入或如何清除它？

谢谢

Answer 1

您必须为element_to_be_clickable() 诱导WebDriverWait，您可以使用以下任一Locator Strategies：

• 使用CSS_SELECTOR：

  password = WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.CSS_SELECTOR, "input[name='password']")))
  password.click()        
  password.clear()
  password.send_keys("Tijmen")
  

• 使用XPATH：

  password = WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.XPATH, "//input[@name='password']")))
  password.click()
  password.clear()
  password.send_keys("Tijmen")
  

• 注意：您必须添加以下导入：

  from selenium.webdriver.support.ui import WebDriverWait
  from selenium.webdriver.common.by import By
  from selenium.webdriver.support import expected_conditions as EC

Mac 不能使用COMMAND 你需要Keys.BACKSPACE 试试：

driver = self.driver
password = driver.find_element_by_xpath("//input[@name='password']")
password.clear()
password.send_keys(password)
password.send_keys(Keys.RETURN)
#password = WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.XPATH, "//input[@name='password']")))
#or
#time.sleep(1)
for i in range(len(password)):
    password.send_keys(Keys.BACKSPACE)
