Python: find_element_by_css_selector

问题:

I am trying to click the login button with webdriver

<a class="login-btn" href="javascript:;" data-bind="click:loginSection.loginClick">
    <span class="btn-text">Login</span>
</a>

My code:

submit=driver.find_element_by_css_selector('a.login-btn').click()

or try this code:

submit=driver.find_element_by_class_name('login-btn').click()

Neither of these is working, need some advice. Thanks in advance

Error:

NoSuchElementException: Message: no such element: Unable to locate element: {"method":"css selector","selector":"a.login-btn"}

To click on the Login button you can use either of the the following line of code :

• LinkText :

  driver.find_element_by_link_text("Login").click()
  

• CssSelector :

  driver.find_element_by_css_selector("a.login-btn > span.btn-text").click()
  

• Getting more granular with the CssSelector you can also use the following line of code :

  driver.find_element_by_css_selector("a.login-btn[data-bind='click:loginSection.loginClick'] > span.btn-text").click()
  

Update : As you are seeing NoSuchElementException you can check this discussion
