1. First, set a progress bar control inside the website/application, and call related functions to track user operation, module loading, data request, etc.

2. Secondly, the key operation modules before and after (such as user login, page jump, data loading, etc. ), set related callback functions, and call different progress bar functions according to different situations.

3. Finally, the display interface of the progress bar is constantly updated according to the real-time changes of data, so that users can know the operation progress and waiting time. At the same time, after the data request or processing is completed, destroy the progress bar control and return to the data or jump page.
