Hello, I am changing the logic part of my javascript project to c ++ using
embind
I have a problem and would like to ask for advice.
First, we change most of the computation and business logic of the existing
project to c ++ and execute the corresponding logic
Invokes a javascript callback asynchronously to change the UI.
I found the data roughly and configured it as below, but it does not work
as I thought throw the error.
logic.cpp
class Logic {
public:
Logic ();
~ Logic ();
std :: function <void ()> callback;
/ **
* /
registerCallback (std :: function <void ()> _cb) {
callback = _cb;
}
/ **
* /
void doSomething () {
blah .........
callback (someClass);
blah ......
}
};
EMSCRIPTEN_BINDINGS (logic_class) {
class_ <Logic> ("Logic")
.constructor <> ()
.function ("registerCallback", & Logic :: registerCallback,
allow_raw_pointers ())
.function ("doSomething", & Logic :: doSomething, allow_raw_pointers ())
}
main.js
window.onload = function () {
blah .........
var logic = .....;
logic.registerClass (callbackFn);
logic.doSomething ();
}
function callbackFn (someClass) {
update ui
}
Is there any place to get the documentation or examples needed to do the
above?
