无法使用selenium（python）找到元素

Question

因此，我尝试查看网站中的 iframe，但无法弄清楚该元素属于何处。我试图通过类名访问元素。下面是我的代码，这是网站。from requests import getfrom bs4 import BeautifulSoupfrom selenium.webdriver import Chromefrom selenium.webdriver.chrome.options import Optionsfrom selenium import webdriverbrowser = webdriver.Chrome(executable_path= '/Users/abeelcf/Downloads/chromedriver')browser.get('https://www.redfin.com')zipcode = input("Enter a zip code to look up: ")search_form = browser.find_element_by_id('search-box-input')search_form.send_keys(zipcode)search_form.submit()#pg 2browser.find_element_by_id("MapHomeCard_0")网址是https://www.redfin.com/zipcode/20007问题出在最后一行。它找不到元素 MapHomeCard_0 ，说该元素没有这样的元素。

Answer 1

在 search_box 提交后，您需要使用网络驱动程序等待等待页面加载。

WebDriverWait(driver, 10).until(EC.presence_of_element_located((By.ID, 'MapHomeCard_0')))

还导入以下内容

from selenium.webdriver.common.by import By

from selenium.webdriver.support.ui import WebDriverWait 

from selenium.webdriver.support import expected_conditions as EC

Answer 2

要定位您需要引发WebDriverWait 的元素visibility_of_element_located()，您可以使用以下任一定位器策略：

• 
  

使用XPATH：

driver.get('https://www.redfin.com')

search_form = WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.XPATH, "//input[@class='search-input-box' and @id='search-box-input'][@title='City, Address, School, Agent, ZIP']")))

search_form.send_keys("20007")

search_form.submit()

print(WebDriverWait(driver, 20).until(EC.visibility_of_element_located((By.XPATH, "//div[@class='homecards']/div[@id='MapHomeCard_0']"))).text)

使用CSS_SELECTOR：

print(WebDriverWait(driver, 20).until(EC.visibility_of_element_located((By.CSS_SELECTOR, "div.homecards>div#MapHomeCard_0"))).text)

控制台输出：

LISTED BY REDFIN
