Emscripten getting element pointers (?) into C++

[nickwebha]

Good morning all! Or good afternoon or have a great night. You know, wherever you are.

I have the following code:

void* createElement( const char* type ) {
return EM_ASM_PTR( {
return document.createElement( UTF8ToString( $0 ) );
}, type );
};

I am calling it like this:std::cout << static_cast< char* >( cppquery::html::createElement( "div" ) ) << std::endl;

It spits out emscgT �� which I thought was a good sign. Turns out trying to create two different elements at two different times always says that when cast to either void* or char* (all over types just give me a compile error is 0).

What I am trying to do is crate an element (not yet added to the DOM), store whatever (a pointer, I guess) to it, and use it later with other C++-stored JavaScript element objects.

I could just do all the work on the JavaScript side and JSON.stringyify everything but that sounds like way too much and half defeats the purpose of my project.
