消息：即使经过了一段时间，元素也仍然无法工作。sleep（）和WebDriverWait

Question

我知道这个问题已经被问过很多次了，但是您如何解决“元素难以处理”的异常呢？

我对Selenium还是很陌生，所以如果我发现错误或误解，请原谅。

我尝试在代码的各个部分中添加time.sleep（20），以查看这是否允许元素加载，但目前还没有成功。

我在这里想念东西吗？

# -*- coding: utf-8 -*-
from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
import time


#Login Credentials
email = 'anexample@fakeemail.com'
password = 'Password123'

#Login to Money Dashboard
driver = webdriver.Chrome(executable_path='/usr/local/bin/chromedriver')
driver.get("https://my.moneydashboard.com/")

loginPageEmail =  WebDriverWait(driver, 20).until(
     EC.presence_of_element_located((By.XPATH, '//*[@id="input_0"]')))

loginPageEmail.send_keys(email)

我总是会遇到以下错误：

     Traceback (most recent call last):
       File "mdash.py", line 26, in <module>
         loginPageEmail.send_keys(email)

Answer 1

如果您每次运行代码时都检查元素ID attribute是否是动态的，那么这里的名称attribute应该是unique attribute才能访问input元素。表单元素不能识别input元素，因此我将表单元素与输入元素和输入元素的唯一属性一起使用。

使用WebdriverWait和elementtobeclickable，然后跟随xpath。

    email = 'anexample@fakeemail.com'
    password = 'Password123'

    #Login to Money Dashboard
    driver = webdriver.Chrome(executable_path='/usr/local/bin/chromedriver')
    driver.get("https://my.moneydashboard.com/")
loginPageEmail = WebDriverWait(driver, 5).until(EC.element_to_be_clickable((By.XPATH, '//form[@name="vm.registerForm"]//div[@class="inputs"]//input[@name="email"]')))
loginPageEmail.send_keys(email)
loginPagepassword = WebDriverWait(driver, 5).until(EC.element_to_be_clickable((By.XPATH, '//form[@name="vm.registerForm"]//div[@class="inputs"]//input[@name="password"]')))
loginPagepassword.send_keys(password)

输出：
