我有一个相对简单的问题。我试图在一个弹出窗口上点击一个按钮，我相信它是与Selenium的javascript。我为Firefox运行了Selenium add，它给了我代码，但它没有用。代码相当长，一切正常，但是当它到达这一行时：
driver.find_element_by_id("cancelExistingReservationButton").click()
它只是等待，然后它出错了这条消息：
该按钮位于屏幕上，但永远不会被点击。我知道代码的一部分可以跟随它，但是我不能让它对该行做任何事情。

您可以尝试这样做以确保按钮已加载并准备好被Selenium点击。

让我们在这里改变逻辑。首先 - 登录，然后打开页面并尝试进行预订。另外，您应该使用visibility_of_element_located预期条件而不是presence_of_element_located：
# log in
driver.get(self.base_url + '/login/')
driver.find_element_by_id('loginPageUsername').send_keys('ourlogin')
driver.find_element_by_id('loginPagePassword').send_keys('ourpassword')
driver.find_element_by_id('loginPageSubmitButton').click()
driver.get(self.base_url + "/dining/grand-floridian-resort-and-spa/1900-park-fare/")
driver.find_element_by_xpath("(//button[@type='button'])[2]").click()
driver.find_element_by_link_text('27').click()
...
if len(availableTimesList) < 4:
for y in range(0, len(allwantedtimes)):
if allwantedtimes[y] in availableTimesList:
driver.find_element_by_xpath(positions[availableTimesList.index(allwantedtimes[y])]).click()
print('We got here at least')
element = WebDriverWait(driver, 10).until(EC.visibility_of_element_located((By.ID, "cancelExistingReservationButton")))
element.click()
print('But never here')
