python - 单击由 JavaScript 使用 Python Webdriver 编写的数据绑定(bind)下的按钮

Question

我可以登录网站，但不知道如何点击“下载为 CSV”。我尝试过 XPATH 和 CSS 选择器。

这是 HTML 的图片。

仪表板与许多小部件结合在一起。不知道这是否会影响什么。 如果您需要更多信息，请告诉我。谢谢:)

下面是代码

看起来小部件总是在同一个位置，如果您在 Windows 上运行它，我通常会尝试使用 X/Y 坐标与 AppRobotic 等宏工具进行单击。如果这是页面加载缓慢的问题，我通常会尝试停止页面加载，并与页面进行一些交互，这样的操作应该适合您:

import win32com.client
from win32com.client import Dispatch
x = win32com.client.Dispatch("AppRobotic.API")
from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC

driver = webdriver.Chrome('chromedriver.exe')
driver.get('https://www.google.com')
# wait 20 seconds
x.Wait(20000)
# scroll down a couple of times in case page javascript is waiting for user interaction
x.Type("{DOWN}")
x.Wait(2000)
x.Type("{DOWN}")
x.Wait(2000)
# forcefully stop pageload at this point
driver.execute_script("window.stop();")
# if clicking Download as CSV button with Selenium still does not work here, use screen coordinates
x.MoveCursor(xCoord, yCoord)
x.MouseLeftClick
x.Wait(2000)
