推荐答案

如果您的用例用于scroll()，则

If your usecase is to scroll() the window containing the DOM document, there is no better way other then using the either of the following Window Methods:

• Window.scrollBy()
• Window.scrollTo()

• Window.scrollBy()
• Window.scrollTo()

如果您的用例用于scroll()一个

Element.scrollIntoView()

您可以在中找到详细的讨论.不同的滚动选项之间有什么区别?

但是，如果要避免execute_script()与 WebElement 进行交互，则可以使用以下两(2)个其他选项:

However, if you want to avoid the execute_script() to interact with a WebElement you have two (2) other options available as follows:

• 使用 move_to_element(). action_chains.html#module-selenium.webdriver.common.action_chains"rel =" nofollow noreferrer> selenium.webdriver.common.action_chains .此方法将自动滚动 视口中的元素.

• Using move_to_element() from selenium.webdriver.common.action_chains. This method will automatically scroll the element within the Viewport.

• 示例代码:

• Example code:

menu = driver.find_element_by_css_selector(".nav")
hidden_submenu = driver.find_element_by_css_selector(".nav #submenu1")
ActionChains(driver).move_to_element(menu).click(hidden_submenu).perform()

使用 expected_conditions -selenium.webdriver.support.wait"rel =" nofollow noreferrer> selenium.webdriver.support.wait 将自动滚动

Using element_to_be_clickable() from selenium.webdriver.support.expected_conditions. This expected_conditions when used in conjunction with selenium.webdriver.support.wait will automatically scroll the element within the Viewport.

• 示例代码:

• Example code:

WebDriverWait(browser, 20).until(EC.element_to_be_clickable((By.LINK_TEXT, "Cart"))).click()
