How can I call C++ callback asynchronously from JavaScript?
This is my JS code:
<script type="text/javascript">
function sendRequest(callback) {
setTimeout(function(){
callback["sayHi"]();
}, 100);
}
</script>
This is my C++ code:
#include <emscripten/emscripten.h>
#include <emscripten/bind.h>
using namespace emscripten;
class MyClass {
public:
void sayHi () {
printf("Hello! \n");
};
};
EMSCRIPTEN_BINDINGS(MyClass)
{
class_<MyClass>("MyClass")
.function("sayHi", &MyClass::sayHi);
}
int main() {
val window = val::global("window");
auto myObj = MyClass();
window.call<void>("sendRequest", myObj);
return 0;
}
When I execute this code in browser it fails with error:
Uncaught BindingError: Cannot pass deleted object as a pointer of type
MyClass*
I use emcc 1.35.22 and compile it with this command:
~/app/emsdk_portable/emscripten/tag-1.35.22/emcc main.cpp --bind -o out.js
Thank you in advance!
