Python Selenium-如何单击javascript按钮

我不熟悉Python和Selenium。我的网站上有一个按钮的以下代码，我无法使用

 driver.find_element_by_id("AddToBasket").click()

或

将鼠标悬停在按钮上只会显示

javascript:void（0）

这是我的代码

<div class="add">
    <a href="javascript:void(0)" id="AddToBasket" class="addtobtn addtobag">
      <span>Add to cart</span>
    </a>

谢谢

from selenium.webdriver.common.action_chains import ActionChains
self.driver = webdriver.Firefox()
# You need a mouse to hover the span elements here
self.mouse = webdriver.ActionChains(self.driver)    

# You need get the span element from its xpath:
value = 'Add to cart'
span_xpath = '//span[contains(text(), "' + value + '")]'
span_element = driver.find_element_by_xpath(span_xpath)

# Then you hover on span element by mouse and click on it:
self.mouse.move_to_element(span_element).click().perform()
