无法将课程代码输入时间表，时间表返回空

Question

我正在为大学时间表创建一个新系统，我正在寻找时间表中的空闲时段（学生没有讲座）。我需要输入课程代码，因为目前它正在打开一个空白的时间表，所以我需要能够在（例如 CASE2）

中输入课程代码

这是我的代码

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


s = Service(ChromeDriverManager().install())
driver = webdriver.Chrome(service=s)
driver.maximize_window() #opens up website, probably not needed. 

driver.implicitly_wait(30)

driver.get('https://opentimetable.dcu.ie/')
df2=pd.read_html(driver.find_element_by_id("week-pdf-content").get_attribute('outerHTML'))[0] 
# currently not searching for anything.

print(df2)

Answer 1

代码必须表现得像真人。

所以你必须

select 下拉菜单和 .click() 打开列表和下一个 select 选项 Programmes of study，或者使用特殊的 class Select()这个，
select 字段 Search 和 .send_key("CASE2"),
select 下面列表中的复选框 [ ] CASE2 和 .click() 它。

已在 Firefox 和 Chrome 上测试 Linux。

from selenium import webdriver
from selenium.webdriver.support.ui import Select

import pandas as pd
import time

driver = webdriver.Chrome()
#driver = webdriver.Firefox()
driver.maximize_window()

driver.implicitly_wait(30)

driver.get('https://opentimetable.dcu.ie/')

select = Select(driver.find_element_by_tag_name("select"))
select.select_by_visible_text('Programmes of Study')

search = driver.find_element_by_id("textSearch")
search.send_keys("CASE2")

#checkbox = driver.find_element_by_xpath('.//input[@type="checkbox"]')  # can find wrong `checkbox` - it would need `time.sleep` until it removes other `checkboxes` 
checkbox = driver.find_element_by_xpath('.//input[following-sibling::div[contains(text(), "CASE2")]]')  # it works but it is harder to remeber
#checkbox = driver.find_element_by_xpath('.//div[contains(text(), "CASE2")]')  # it works (in this HTML) and it is simpler to remeber
checkbox.click()

time.sleep(3)  #  JavaScript needs time to replace data in table

html = driver.find_element_by_id("week-pdf-content").get_attribute('outerHTML')
df2 = pd.read_html(html)[0] 

print(df2.to_string()) # to_string() to display all columns without `...`

无法将课程代码输入时间表，时间表返回空
