python - Selenium + Python : How to stop page loading when certain element gets loaded?

Question

当页面使用AJAX时可以使用隐式和显式等待，但我想在加载足够的元素时停止由driver.get()引起的加载。是否可以这样做，因为 driver.get() 调用仅在页面完成加载时返回。

Answer 1

是的，可以通过将 pageLoadStrategy 功能设置为 none 来实现。然后等待元素出现并调用 window.stop 停止加载:

from selenium import webdriver
from selenium.webdriver.common.desired_capabilities import DesiredCapabilities
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
from selenium.webdriver.common.by import By

capa = DesiredCapabilities.CHROME
capa["pageLoadStrategy"] = "none"

driver = webdriver.Chrome(desired_capabilities=capa)
wait = WebDriverWait(driver, 20)

driver.get('http://stackoverflow.com/')

wait.until(EC.presence_of_element_located((By.CSS_SELECTOR, '#h-top-questions')))

driver.execute_script("window.stop();")
