无法在单击JavaScript上执行硒 - python

我正在尝试从TripAdvisor中抓取一些数据，并使用Python绑定的Selenium来完成它。

网页中的审阅对象有时在底部有一个"更多"按钮，以便在单击它时显示完整的审阅内容。它实际上是一个 span 元素，带有为其编写的 onlclick JS 函数。

我想要实现的是加载页面，找到"更多"链接并单击它们，以便在抓取操作开始之前显示网页完全加载的评论。

到目前为止，我已经尝试了以下代码，但没有运气。我似乎无法理解堆栈跟踪中显示的错误。

import os
import time
from selenium import webdriver
driver = webdriver.Firefox()
driver.get("https://www.tripadvisor.ca/Attraction_Review-g304138-d317476-Reviews-Temple_of_the_Tooth_Sri_Dalada_Maligawa-Kandy_Central_Province.html#REVIEWS");
more = [];
more = driver.find_elements_by_class_name('moreLink')
print(len(more));
for x in range(0,len(more)):
    if more[x].is_displayed():
        more[x].click();
        print("clicked");

这些是我在控制台中收到的错误日志。

任何帮助都非常感谢。
