带有seleniumwebdriver的鼠标滚轮,在没有滚动条的元素上?

我正在尝试驱动类似于Google Maps的网络地图的一部分,在该地图上,通过鼠标悬停时的滚动来进行放大/缩小。理想情况下,我希望能够执行以下操作:

someElement.scroll(-50)

我在文档中看到的最接近的方法是clicksend_keys,但是这两个方法都不可以滚动。我也尝试通过Javascript将滚动条发送到页面,例如,driver.execute_script("scroll(0,-50)")这似乎没有任何作用。

我怎样才能做到这一点?

回答:

要重现/测试鼠标滚轮,您必须通过脚本注入将mouseovermousemovewheel事件发送到顶部元素。

这是Google Map的工作示例:

from selenium import webdriver

from selenium.common.exceptions import WebDriverException

def wheel_element(element, deltaY = 120, offsetX = 0, offsetY = 0):

error = element._parent.execute_script("""

var element = arguments[0];

var deltaY = arguments[1];

var box = element.getBoundingClientRect();

var clientX = box.left + (arguments[2] || box.width / 2);

var clientY = box.top + (arguments[3] || box.height / 2);

var target = element.ownerDocument.elementFromPoint(clientX, clientY);

for (var e = target; e; e = e.parentElement) {

if (e === element) {

target.dispatchEvent(new MouseEvent('mouseover', {view: window, bubbles: true, cancelable: true, clientX: clientX, clientY: clientY}));

target.dispatchEvent(new MouseEvent('mousemove', {view: window, bubbles: true, cancelable: true, clientX: clientX, clientY: clientY}));

target.dispatchEvent(new WheelEvent('wheel', {view: window, bubbles: true, cancelable: true, clientX: clientX, clientY: clientY, deltaY: deltaY}));

return;

}

}

return "Element is not interactable";

""", element, deltaY, offsetX, offsetY)

if error:

raise WebDriverException(error)

options = webdriver.ChromeOptions()

options.add_argument("--disable-infobars --disable-extensions --window-size=1366,768")

driver = webdriver.Chrome(chrome_options=options)

driver.get("https://www.google.co.uk/maps")

# get element

elm = driver.find_element_by_css_selector("#scene > div.widget-scene > canvas")

# zoom in with mouse wheel

wheel_element(elm, -120)

# zoom out with mouse wheel

wheel_element(elm, 120)

作为替代方案,您可以发送Google地图+/-的缩放比例:

# get element

elm = driver.find_element_by_css_selector("#scene > div.widget-scene > canvas")

# zoom in with shortcut

elm.send_keys("+")

# zoom out with shortcut

elm.send_keys("-")
