英文:
Using Selenium to click a input type submit button
问题
尝试点击这个
<input type="submit" value="Log In" class="btn btn-lg btn-primary btn-block">
我已经尝试过
driver.find_element("class", "btn").click()
driver.find_element("class", "btn btn-lg btn-primary btn-block").click()
driver.find_element("value", "Log In").click()
但都出现错误
InvalidArgumentException: Message: invalid argument: invalid locator
如何点击它？
编辑：
现在我尝试过
driver.find_element(By.CLASS_NAME, "btn btn-lg btn-primary btn-block").click()
但出现错误
NoSuchElementException: Message: no such element: Unable to locate element: {"method":"css selector","selector":".btn btn-lg btn-primary btn-block"}

尝试使用 "By"：
from selenium.webdriver.common.by import By
您可以以不同的方式选择元素：
按类名：
driver.find_element(By.CLASS_NAME, "btn btn-lg btn-primary btn-block").click()
按XPATH：
driver.find_element(By.XPATH, '//input[@value="Log In"]').click()
按CSS选择器：
driver.find_element(By.CSS_SELECTOR, 'input.btn.btn-lg.btn-primary.btn-block').click()

英文:
Try using "By"
from selenium.webdriver.common.by import By
And you can select your element it in different ways:
By Class:
driver.find_element(By.CLASS_NAME, "btn btn-lg btn-primary btn-block").click()
By XPATH:
driver.find_element(By.XPATH, '//input[@value="Log In"]').click()
By CSS selector:
driver.find_element(By.CSS_SELECTOR, 'input.btn.btn-lg.btn-primary.btn-block').click()
