单击 JavaScript 页面中的按钮 - Selenium/Python

Question

我的代码访问了一个页面，我试图单击菜单列表上显示“医师计划”的按钮。如果您在浏览器上单击此按钮，它会将您定向到一个新网页。

但是，页面的 html 上没有 href 可以帮助我通过代码找到此链接（我假设是因为它是 JavaScript？）目前，我只使用了它的 Xpath。

我的问题是 - 如果我能够在浏览器中点击它，我不应该能够使用 Selenium 点击它吗？如果是这样，如何做到这一点？

import time
from bs4 import BeautifulSoup
from selenium import webdriver
driver = webdriver.Chrome()

driver.get('https://www.kidney.org/spring-clinical/program')
time.sleep(6)
page_source = driver.page_source
soup = BeautifulSoup(page_source, 'html.parser')
element1 = driver.find_element_by_xpath('//*[@id="dx-c7ad8807-6124-b55e-d292-29a4389dee8e"]/div')
element1.click()

Answer 1

元素在 iframe 内，需要切换到 iframe

driver.switch_to.frame("SCM20 Advanced Practitioner Program")
element1 = driver.find_element_by_xpath("//div[text()='Physician Program']")
element1.click()

理想情况下，您应该使用webdriverwait 并等待框架可用。

WebDriverWait(driver,10).until(EC.frame_to_be_available_and_switch_to_it((By.NAME,"SCM20 Advanced Practitioner Program"))) 
WebDriverWait(driver, 10).until(EC.element_to_be_clickable((By.XPATH "//div[text()='Physician Program']"))).click()

您需要导入以下库

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

Answer 2

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

import subprocess
#other imports
import time
from bs4 import BeautifulSoup
from selenium import webdriver
driver = webdriver.Chrome()

driver.get('https://www.kidney.org/spring-clinical/program')
time.sleep(6)
page_source = driver.page_source
soup = BeautifulSoup(page_source, 'html.parser')
frame= WebDriverWait(driver,10).until(EC.presence_of_element_located(
    (By.NAME, "SCM20 Advanced Practitioner Program")))
driver.switch_to.frame(frame)
options = WebDriverWait(driver, 10).until(EC.visibility_of_all_elements_located(
    (By.CSS_SELECTOR, '[class="track-selector-popup"] [role="option"]')))

options[0].click()

input()

元素在 iframe 内，因此切换到它并使用等待，切换​​回并与框架外的元素交互使用：

  driver.switch_to.default_content()
