硒找不到实际存在的元素

Question

我正在自动化一个枯燥的数据输入任务，所以我创建了一个程序，基本上是使用Selenium为我点击和键入。它跑得很好！除非它到达这个特定的“编辑详细信息...”元素，但是，无论我尝试什么方法，selenium都无法找到该元素。

我尝试使用一个CSS选择器来访问ID,但没有成功。我还尝试使用XPATH,并尝试通过给它一个带有按钮文本的'contains'语句来更加具体。最后，我使用selenium IDE查看当我实际单击按钮时它注册了什么定位器，并且它使用了与我在代码中声明的完全相同的ID。我完全不知道该如何解决这个问题。

from selenium import webdriver
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.support import expected_conditions as EC
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.common.exceptions import *

import pyautogui as py
import time, sys, os, traceback


#Launching Browser
browser = webdriver.Ie()
wait = WebDriverWait(browser, 15) #Waiting


#Laziness Functions
def clickCheck(Method, Locator, elemName):
    wait.until(EC.element_to_be_clickable((Method, Locator)))
    print(elemName + ' Clickable')




#Commence main function
try:

    #Do alot of Clicks and Stuff until it reaches "Edit Details..." element

    """THIS IS WHERE THE PROBLEM LIES"""
    time.sleep(3)
    clickCheck(By.CSS_SELECTOR, 'td[id="DSCEditObjectSummary"]', "Edit Details")
    elemEdit = browser.find_element_by_css_selector('td[id="DSCEditObjectSummary"]')
    elemEdit.click()




#FAILSAFES

except:
    print('Unknown error has Occured')
    exc_info = sys.exc_info()
    traceback.print_exception(*exc_info)
    del exc_info

finally: #Executes at the end and closes all processes
    print('Ending Program')
    browser.quit()
    os.system("taskkill /f /im IEDriverServer.exe")
    sys.exit()

raise exception_class(message, screen, stacktrace)
selenium.common.exceptions.NoSuchElementException: Message: Unable to find element with css selector == [id="DSCEditObjectSummary"] 

编辑详细信息“按钮

看起来问题可能与页面加载缓慢有关，或者正如另一位评论者所说的是在iFrame中，等等。如果你在Windows上运行，我通常会尝试使用X/Y坐标和宏工具（如AppRobotic）来点击。如果是页面加载速度慢的问题，我通常会尝试停止页面加载，并与页面进行一点交互，这样的操作应该对您有用：

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

import pyautogui as py
import time, sys, os, traceback

#Launching Browser
browser = webdriver.Ie()
wait = WebDriverWait(browser, 15) #Waiting


#Laziness Functions
def clickCheck(Method, Locator, elemName):
    wait.until(EC.element_to_be_clickable((Method, Locator)))
    print(elemName + ' Clickable')

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 with Selenium still does not work here, use screen coordinates
x.MoveCursor(xCoord, yCoord)
x.MouseLeftClick
x.Wait(2000)
