python selenium无法清除输入字段

Question

I try to select my input with selenium but when I use this it doesn't work:

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)

I am using Mac so Keys.CONTROL doesn't work, can anyone help me how to select the input or how to clear it?

Thanks

Answer 1

You have to induce WebDriverWait for the element_to_be_clickable() and you can use either of the following Locator Strategies :

• Using 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")

• Using XPATH :

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

• Note : You have to add the following imports :

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

Mac cannot use COMMAND you need Keys.BACKSPACE Try:

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)
