I want to create a app. The app should be log in first and then enter the system. Can streamlit use the button to refresh the html page or return a new html page.Thank you.

Hi @nelson_wu and welcome to the forum :wave:

We’ve been discussing that over here Please take a look and let me know if you have any questions.

Also, one of our major goals for 2020 is Streamlit plugin system which will give you the ability to write arbitrary JavaScript code and insert it into your app. This opens the door for a lot of possibilities for custom solutions to layout, visualization, interactivity with chart/maps/tables, and other unique needs of your app. You can help design this feature or follow its progress over there

P.S. Thanks for using Streamlit!
