    javascript - Keydown event on Ace Editor - Stack Overflow

    On this amazing editor (Ace: Code Editor), there's a method which I can get the on change event, is there a on keydown event? Or a hack I can simulate it?

    There is no keydown event, you can add keydown event listener on textarea returned by editor.textInput.getElement(), but the better way is to use editor.mands.addCommand

    editor.mands.addCommand({
    name: "...",
    exec: function() {},
    bindKey: {mac: "cmd-f", win: "ctrl-f"}
})

    or editor.keyBinding.addKeyboardHandler

    I can't find it in the documentation, but in this discussion, I found out about the editor.mands.on('afterExec', ...) API:

    editor.mands.on('afterExec', eventData => {
    if (eventData.mand.name === 'insertstring') {
        console.log('User typed a character: ' + eventData.args);
    }
});

    afterExec fires on every mand in the editor. Commands include actions like typed text, appearance of pletion popups on ctrl+space, etc...

    It's not a direct analog of keydown event, but it is the thing I was googling for when I came here, so hopefully you'll find it useful.
