Hot to interact with DOM?

[krm441]

I have read all the possible tutorials and docs. But i still don't understand how i can use a simple html button to invoke some changes in my c++. For example:
<div><button onclick="jump()"> Button </button></div>

in C++;
inline void jump() { Player::GetInstance()->jump(); }
How can I do that?

Please forgive me; emscripten is a new area for me. I use glfw and on desktop it perfectly responds to all keys. But I need to create a GUI. So i thought that using html/css buttons will be a good idea.

The simplest way to make the work would be to export the jump function. Do do that you can either tag it with EMSCRIPTEN_KEEPALIVE or add it to -sEXPORTED_FUNCTIONS on the command line.

Also if you are writing it in C++ you will need to mark it as extern "C".

Finally when can call a native function from JS you need to prefix it with a leading underscore. So that call would be _jump() or Module._jump()
