Python through JS control scroll bar Pull the full text through psutil get PID window handle, through Win32gui to make the program window front through Pyauto implement right-click menu and Save as Operation

1. Reference

Automate fast with Python + Selenium

Use Python + Selenium to implement a specified element of the page (a truncated graph element)

Use Python to get all the process PID and process name of the system

Reference method for Python to lock focus to the specified process window

2. Improve JS code, pull down and pull up, accurately determine whether the load is over

Import time

3. Position the window via PID Process number and window caption and forward

4. Right-click Operation via Autopy, and save page as
