无法找到元素或切换到框架

Question

因此，我正在关注有关YouTube机器人的YouTube教程（https://www.youtube.com/watch?v=BGU2X5lrz9M），但它始终会给我错误

Unable to locate element:

我无法弄清楚出了什么问题，发现的所有问题都表明我可以切换到frame或iframe，但是本教程中的人不必这么做，而且我也无法弄清楚该怎么做。开关。请帮帮我！

这是代码

    driver = self.driver
    driver.get('https://www.instagram.com/')
    time.sleep(2)
    login_button = driver.find_element_by_xpath('//*[@id="react-root"]/section/main/article/div[2]/div[2]/p/a')
    login_button.click()
    time.sleep(2)
    username_elem = driver.find_element_by_xpath('//*[@id="f2fdc3b5774d3f4"]')
    username_elem.clear()
    username_elem.send_keys(self.username)
    password_elem = driver.find_element_by_xpath('//*[@id="f25923ff3b40138"]')
    password_elem.clear()
    password_elem.send_keys(self.password)
    password_elem.send_keys(Keys.RETURN)
    time.sleep(2)

Answer 1

与框架无关，但输入形式的元素ID已更改

选择by name

更安全

driver.get('https://www.instagram.com/')

login_button = driver.find_element_by_link_text('Log in')
login_button.click()
time.sleep(2)
username_elem = driver.find_element_by_name('username')
username_elem.clear()
username_elem.send_keys(self.username)
password_elem = driver.find_element_by_name('password')
password_elem.clear()
password_elem.send_keys(self.password)
password_elem.send_keys(Keys.RETURN)
time.sleep(2)
