出于个人学习的目的，我创建了这个简短的脚本，目的是打开Facebook帖子的链接，点击所有的“添加好友”按钮，同时滚动条滚动列表。为了避免垃圾邮件，我添加了选择最大添加人数和请求间隔时间的功能。

我有可执行的完整代码（在问题的最后公布），但有问题。我如何在向下滚动列表的同时点击与设置相关的“添加好友”按钮，以选择添加的最大人数和一个请求与另一个请求之间的时间？

**（正确向下滚动）**如果我只是这样写，那么滚动条会向下

i = 1

while True:
i = i + 1

row = wait.until(EC.visibility_of_element_located((By.XPATH, f"(//div[@data-visualcompletion='ignore-dynamic' and not (@role) and not (@class)])[{i}]")))

driver.execute_script("arguments[0].scrollIntoView(true);", row)

**（不能正确向下滚动）**例如，如果我添加五线谱以单击所有按钮，滚动条不再下降（只自动单击第一个“添加朋友”按钮，因此您不会单击下面的按钮，我也希望单击下面的按钮）

wait = WebDriverWait(driver, 30)
i = 1

while True:
i = i + 1

row = wait.until(EC.visibility_of_element_located((By.XPATH, f"(//div[@data-visualcompletion='ignore-dynamic' and not (@role) and not (@class)])[{i}]")))
add = WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.XPATH, "//span[text()='Add friend']"))).click()
close_popup = WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.XPATH, "//span[text()='Ok']"))).click()

driver.execute_script("arguments[0].scrollIntoView(true);", row, add, close_popup)
