Go language uses Go-sciter to create desktop Apps (ii) UI elements find, add, delete, modify

We can use Go-sciter to provide us with the method, convenient to Html,css written UI interface for the enhancement and deletion of the search.

The Demo3.go code is as follows:

Package Main;import ("Github.com/sciter-sdk/go-sciter" "Github.com/sciter-sdk/go-sciter/window" "Log" "FMT")// Some basic operation func base (Root *sciter.
