python-3.x - 不能多次滚动一个 div | 硒 | Python

问题描述

当我运行它时，它只能向下滚动一次，并抛出“消息：元素不可交互”错误。（它应该滚动两次）。当我尝试循环运行它（尝试并忽略错误）并手动滚动它时，它会不断将我推回到特定位置。但这很奇怪，因为我在这里使用箭头键，而不是移动到元素：

ActionChains(driver).move_to_element(driver.sl.find_element_by_id('my-id')).perform()

我已经尝试过：给所有东西更多的时间来加载睡眠，将鼠标悬停在元素上并单击它以使其可交互，使用其他方法滚动，例如这个和其他类似的方法：driver.execute_script("window.scrollTo(0, Y)")

我现在很迷茫，不知道该怎么办

解决方案

If you want to scroll that list of persons liked that page you can do this:

like_meter = driver.find_element_by_class_name('zV_Nj')
like_meter.click()

sleep(1)

elem = driver.find_element_by_css_selector("div[role='dialog'] div[style*='padding']")

for n in range(10):
    driver.execute_script("arguments[0].scrollDown += 20", elem)

The range of 10 and 20 pixels scrolling can be changed according to your needs
