WebOpenGL is a rendering system. Rendering has nothing to do with getting text input. If you want text input, then you're going to have to use a library or OS system that provides it. SDL, Allegro, SFML, and most of the other "multimedia" libraries all have some means of getting input from the user. WebOpenGL functions are obtained by using function pointers. The general procedure is: Somehow obtain function pointer types (essentially the function prototypes) Declare each function we would like to use (with its function pointer type) Obtain the actual function For example, consider glBegin:
