Use selenium to directly interact with js in the current page
Execute Js scripts using selenium
To use js, you must first know how to use js. Now, let’s take a simple example. Let’s use 12306 as an example. The date selection box on the home page can only be manually selected for the corresponding time, because it is a readonly attribute, which needs to be changed to auto
If you want to choose automatically, you need to modify it through js. In the console, we can easily operate, as shown in the figure:
If you use selenium, the idea is the same, first remove the readonly attribute through js, and then execute js to change its time and date, the code is as follows
# Base 为上一章节的base.py默认继承下来的东西
from base import Base
import pytest
import time
class TestJs(Base):
def test_js(self):
url = 'https://www.12306.cn/index/'
self.driver.get(url)
date_js = 'document.getElementById("train_date").removeAttribute("readonly")'
self.driver.execute_script(date_js)
time.sleep(2)
date_js2 = 'document.getElementById("train_date").value="2024-06-30"'
self.driver.execute_script(date_js2)
# ss = self.driver.find_element_by_xpath('//*[@id="train_date"]').text
# print(f'更改之后当前的日期为:{ss}')
if __name__ == '__main__':
pytest.main(["-vs", "test_chromjs.py"])
Finally: If you don’t want to experience the feeling of not being able to find information when learning, no one answering questions, and giving up after persisting for a few days, here I will share with you some learning resources for automated testing, hoping to give you some guidance on the way forward.
