通过Python使用find_element时Selenium找不到元素

Question

不断收到unable to locate element错误消息。

xpath 的第一个查找元素很好，但第二个让我很难过。

这是我的代码：

import XLUtils

from selenium import webdriver

driver=webdriver.Chrome(executable_path="C:\Chrome_Driver\Chromedriver.exe")

driver.get("https://www.canada.ca/en/revenue-agency/services/e-services/e-services-businesses/payroll-deductions-online-calculator.html")

driver.find_element_by_xpath('/html/body/main/div[1]/div[7]/p/a[1]').click()

driver.find_element_by_xpath('//*[@id="welcome_button_next"]').click()

Answer 1

您需要稍等片刻，Next按钮才会出现。from selenium.webdriver.support import expected_conditions as ECfrom selenium.webdriver.common.by import Byfrom selenium.webdriver.support.wait import WebDriverWaitwait = WebDriverWait(driver, 10)e = wait.until(    EC.presence_of_element_located((By.XPATH, '//*[@id="welcome_button_next"]'))    )e.click()

Answer 2

要单击文本为Next的元素，您需要诱导WebDriverWait以使元素可单击，您可以使用以下任一解决方案：使用CSS_SELECTOR：WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.CSS_SELECTOR, "input.btn.btn-primary#welcome_button_next"))).click()使用XPATH：WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.XPATH, "//input[@class='btn btn-primary' and @id="welcome_button_next"]"))).click()注意：您必须添加以下导入：from selenium.webdriver.support.ui import WebDriverWaitfrom selenium.webdriver.common.by import Byfrom selenium.webdriver.support import expected_conditions as EC
