我正在尝试自动化this Instagram链接。我需要滚动并滚动并获取所有链接。我正在尝试关注但不工作。

除了宏杰李回答

driver.execute_script("return arguments[0].scrollIntoView();", element_obj)

另外，如果你想做一个额外的滚动：

driver.execute_script("return arguments[0].parentNode.scrollTop = "
                      "arguments[0].parentNode.scrollTop + {extra_scroll}"
                      .format(extra_scroll=extra_scroll_pixels), element_obj)

我的整个代码：

def _scroll_to_element(driver, element,
                       extra_scroll=None):
    # Scroll to element
    driver.execute_script("return arguments[0].scrollIntoView();", element)

    # Scroll parentNode with the extra pixels (If provided)
    if extra_scroll:
        driver.execute_script(
            "return arguments[0].parentNode.scrollTop = "
            "arguments[0].parentNode.scrollTop + {extra_scroll}".format(
                extra_scroll=str(extra_scroll)), element)
