f 不打印到 console.log

<button type="button" id="keyboard">Keyboard</button>

<script>
    var kbd = document.getElementById( "keyboard" );

    kbd.focus();

    kbd.addEventListener( "keypress", function( event ) {
        if ( event.keyCode == 32 ) {
            if ( player.getPlayerState() == 1 ) {
                console.log('pressed spacebar 1');
                player.pauseVideo();
            }
            else {
                console.log('pressed spacebar 2');
                player.playVideo();
            }
        }
        if ( event.keyCode == 70 ) {
            console.log('pressed letter f');
        }
    });
</script>

编辑:

与 keypress 102 . 与 keydown 正确的密码是 70 32 不管是哪一个。

F是102!。下面就行了

<button type="button" id="keyboard">Keyboard</button>

<script>
var kbd = document.getElementById( "keyboard" );

kbd.focus();

kbd.addEventListener( "keypress", function( event ) {
    if ( event.keyCode == 32 ) {
        if ( player.getPlayerState() == 1 ) {
            console.log('pressed spacebar 1');
            player.pauseVideo();
        }
        else {
            console.log('pressed spacebar 2');
            player.playVideo();
        }
    }
    if ( event.keyCode == 102 ) {
        console.log('pressed letter f');
    }
});
