Selenium 没有通过 id 找到元素 (python)

Question

这是 html 元素：

<button role="button" title="Meeting beitreten" id="interstitial_join_btn" class="style-rest-1IrDU style-theme-green-22KBC style-join-button-yqbh_ style-size-huge-3dFcq style-botton-outline-none-1M0ur" tabindex="1" aria-label="Meeting beitreten" aria-describedby="current_select_status" data-doi="MEETING:JOIN_MEETING:MEETSIMPLE_INTERSTITIAL">Meeting beitreten</button>

我的代码是：

option = webdriver.ChromeOptions()
option.add_argument("--mute-audio")
browser = webdriver.Chrome("C:/Users/leand/Desktop/kahoot-answer-bot-master/chromedriver.exe",options=option)
browser.get(url + "?launchApp=true")
browser.find_element_by_id('interstitial_join_btn').click()

但是我得到这个错误：

Exception in Tkinter callback
Traceback (most recent call last):
  ...here is some info about the files etc...
selenium.common.exceptions.NoSuchElementException: Message: no such element: Unable to locate element: {"method":"css selector","selector":"[id="interstitial_join_btn"]"}
  (Session info: chrome=89.0.4389.90)

我做错了什么或者有其他方法可以点击这个元素吗？

Answer 1

似乎同步issue.To点击使用WebDriverWait()等待element_to_be_clickable()

WebDriverWait(driver,20).until(EC.frame_to_be_available_and_switch_to_it((By.ID,"pbui_iframe")))    WebDriverWait(browser,10).until(EC.element_to_be_clickable((By.ID,"interstitial_join_btn"))).click()

导入以下库

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

如果上面的代码给你 timeout error 然后检查该按钮是否出现在 iframe 或 #shadowroot element

内

更新: 元素在iframe中需要切换。

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

browser=webdriver.Chrome()
browser.get("https://meet37.webex.com/webappng/sites/meet37/meeting/download/7050764c36568ef62dd56dd671cb73c1?launchApp=true")
wait=WebDriverWait(browser,20)
wait.until(EC.frame_to_be_available_and_switch_to_it((By.ID,"pbui_iframe"))) 
wait.until(EC.element_to_be_clickable((By.XPATH,"//input[@placeholder='Your full name']"))).send_keys("user1")
wait.until(EC.element_to_be_clickable((By.XPATH,"//input[@placeholder='Email address']"))).send_keys("Testuser@gmail.com")
wait.until(EC.element_to_be_clickable((By.ID,"guest_next-btn"))).click()
wait.until(EC.element_to_be_clickable((By.ID,"interstitial_join_btn"))).click()

要 select 必须首先从浏览器加载 selenium 上的项目，因此您需要等待几秒钟，直到所有 html 元素加载完毕，然后 select 它们

您可以像这样使用 time.sleep() 函数：

time.sleep(2.0) // 2.0 = 2seconds
<button role="button" title="Meeting beitreten" id="interstitial_join_btn" class="style-rest-1IrDU style-theme-green-22KBC style-join-button-yqbh_ style-size-huge-3dFcq style-botton-outline-none-1M0ur" tabindex="1" aria-label="Meeting beitreten" aria-describedby="current_select_status" data-doi="MEETING:JOIN_MEETING:MEETSIMPLE_INTERSTITIAL">Meeting beitreten</button>
