I am use this Python 3 code to get some download url from webpage, when the webpage opened, I want to send a click event to the element, and trigger to generate download url, then fetch the download url, but now I could not trigger click event,shows error like this:

selenium.common.exceptions.NoSuchElementException: Message: no such element: Unable to locate element: {"method":"css selector","selector":"aplayer-list-download iconfont icon-xiazai"}
  (Session info: chrome=96.0.4664.55)

and this is my code to trigger the download event:

from selenium.webdriver.chrome.service import Service
from selenium import webdriver
from selenium.webdriver.common.by import By
from webdriver_manager.chrome import ChromeDriverManager


class FetchMusic:

    def __init__(self):
        print("fetch...")


if __name__ == '__main__':
    s = Service(ChromeDriverManager().install())
    driver = webdriver.Chrome(service=s)
    # driver.maximize_window()
    driver.get('http://tool.liumingye.cn/music/?page=audioPage&type=migu&name=Unstoppable')
    driver.implicitly_wait(5)
    driver.find_element(By.CSS_SELECTOR, "aplayer-list-download iconfont icon-xiazai").click()
    modal_body = driver.find_element(By.CLASS_NAME, "modal-body").get_attribute("href")
    # results = driver.page_source
    for result in modal_body:
        print(result.text)

what should I do to make it work?

CodePudding user response：

You forgot to add class selector . before classes names.

driver.find_element(By.CSS_SELECTOR, ".aplayer-list-download.iconfont.icon-xiazai").click()

and the next line will not work

modal_body = driver.find_element(By.CLASS_NAME, "modal-body").get_attribute("href")

because the modal body div has not attribute called href, so in case you want to extract all URLs inside modal-body div you can use querySelector API from Javascript. see below

urls = [a.get_attribute('href') for a in driver.execute_script('return document.querySelectorAll(".modal-body a[href*=\'http\']")')]
