元素 不可交互 Selenium Python

Question

I am trying to send keys to the text box on https://www.wolframalpha.com/ but as you can see I was hit with an error. I've tried looking thru the elements but nothing seems to be working if you are able to help I will be thankful. using python3.7, my code:

from selenium import webdriver
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.common.action_chains import ActionChains
import time 
from selenium.webdriver.support import expected_conditions as EC
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.common.by import By

options = webdriver.ChromeOptions() 
options.add_experimental_option("excludeSwitches", ["enable-logging"])
driver = webdriver.Chrome(options=options, executable_path=r'C:\Program Files (x86)\Chrome\Application\chromedriver.exe')

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

driver.find_element_by_xpath('_9CcbX').send_keys('1+1')

error

Answer 1

First of all, you get NoSuchElementException , because you are searching by xpath, with class-name argument. ( _9CcbX is a class name). Instead, you can copy element's correct xpath:

• inspect
• right-click element
• copy -> copy full xpath

This will give you:

driver.find_element_by_xpath('/html/body/div/div/div/div/div/div[1]/section/form/div/div/input').send_keys('1+1')

Second of all, you should use WebdriverWait to be sure the element has loaded and is interactable.

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

xpath = '/html/body/div/div/div/div/div/div[1]/section/form/div/div/input'
element = wait.until(EC.element_to_be_clickable(driver.find_element(By.XPATH, xpath)))
element.send_keys('1+1')
