library_glfw.js blocks html inputs

[uysalibov]

Why is the marked area in the link I gave in the glfw necessary? Although I do not use any key event in my own project, “backspace” and “tab” do not work in the inputs in html because of this marked field.

emscripten/src/library_glfw.js

Lines 416 to 425 in 94f4173

	onKeydown: (event) => {
	GLFW.onKeyChanged(event.keyCode, 1); // GLFW_PRESS or GLFW_REPEAT
	// This logic comes directly from the sdl implementation. We cannot
	// call preventDefault on all keydown events otherwise onKeyPress will
	// not get called
	if (event.keyCode === 8 /* backspace */ || event.keyCode === 9 /* tab */) {
	event.preventDefault();
	}
	},

This doesn't answer your question but that code is duplicated from:

emscripten/src/library_sdl.js

Lines 687 to 694 in fa5bc28

	case 'keydown': case 'keyup': case 'keypress': case 'mousedown': case 'mouseup':
	// If we preventDefault on keydown events, the subsequent keypress events
	// won't fire. However, it's fine (and in some cases necessary) to
	// preventDefault for keys that don't generate a character. Otherwise,
	// preventDefault is the right thing to do in general.
	if (event.type !== 'keydown' || (!SDL.unicode && !SDL.textInput) || (event.keyCode === 8 /* backspace */ || event.keyCode === 9 /* tab */)) {
	event.preventDefault();
	}

So I guess SDL programs have the same issue?

Yes, probably it has same issue too.
