问题描述
我是Selenium的新手，只是设法编写这些代码。 我想点击右下方的“>”链接来删除表格中的数据。 第一次点击有效，但接下来的两次没有。 我错过了什么？ 谢谢。
# coding: utf-8
from selenium import webdriver
from selenium.webdriver.common.by import By
browser = webdriver.Firefox()
browser.get('http://s.cafef.vn/Lich-su-giao-dich-HSG-1.chn')
next_page_link = browser.find_element_by_partial_link_text('>')
next_page_link.click()
next_page_link = browser.find_element_by_partial_link_text('>')
next_page_link.click()
next_page_link = browser.find_element_by_partial_link_text('>')
next_page_link.click()
这是例外

第二个next_page_link.click()调用在浏览器加载下一页之前发生。
添加与 ：
from selenium import webdriver
import selenium.webdriver.support.ui as UI
from selenium.webdriver.common.by import By
import selenium.webdriver.support.expected_conditions as EC
import contextlib
with contextlib.closing(webdriver.Firefox()) as browser:
browser.get('http://s.cafef.vn/Lich-su-giao-dich-HSG-1.chn')
wait = UI.WebDriverWait(browser, 10)
for i in range(3):
next_page_link = wait.until(
EC.element_to_be_clickable((By.PARTIAL_LINK_TEXT, '>')))
next_page_link.click()

通常来自unutbu的anwser就足够了。
我使用.net而不是python的selenium所以我不能给出python的详细代码但是为了稳定你应该等待3次：
-
等待下一页或加载的ajax内容，在这种情况下，您应该等到
.CafeF_Paging td span strong文本是您排除的页码。 -
等待jquery加载，直到jQuery.active == 0
查看 - 等待元素可见，不仅定位，使用visibility_of_element_located。
