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click
和send_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mouseover
,mousemove
和wheel
事件发送到顶部元素。
这是Google Map的工作示例:
from selenium import webdriverfrom 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 elementelm = 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("-")
