Selenium + Python:如何在加载某些元素时停止页面加载? [英] Selenium + Python: How to stop page loading when certain element gets loaded?

问题描述

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.

The implicit and explicit waits can be used when the page uses AJAX, but I want to stop the loading caused by driver.get() when sufficient elements are loaded. Is it possible to do so because of the driver.get() call returns only when the page finishes loading.

推荐答案

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:

Yes it's possible by setting the pageLoadStrategy capability to none. Then wait for an element to be present and call window.stop to stop the loading:

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();")
