javascript - 在 Javascript 中实现与全屏相反的功能

Question

我使用这段代码实现全屏按钮，效果很好。 我想做相反的事情，我该怎么做？ 感谢您的帮助。

HTML

            <button type="button" id="full-screen" class="full-screen">
                <svg version="1.1" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" width="32" height="32" viewBox="0 0 32 32">
                    <path d="M32 0h-13l5 5-6 6 3 3 6-6 5 5z"></path>
                    <path d="M32 32v-13l-5 5-6-6-3 3 6 6-5 5z"></path>
                    <path d="M0 32h13l-5-5 6-6-3-3-6 6-5-5z"></path>
                    <path d="M0 0v13l5-5 6 6 3-3-6-6 5-5z"></path>
                </svg>
            </button>

JavaScript var fullScreenButton = document.getElementById("全屏");

            // Event listener for the full-screen button
            fullScreenButton.addEventListener("click", function()
            {
                if (player.requestFullscreen)
                {
                    player.requestFullscreen();
                }
                else if (player.mozRequestFullScreen)
                {
                    player.mozRequestFullScreen(); // Firefox
                }
                else if (player.webkitRequestFullscreen)
                {
                    player.webkitRequestFullscreen(); // Chrome and Safari
                }
            });

你可以使用这个函数:

function exitFullscreen() {
    if (document.exitFullscreen) {
        document.exitFullscreen();
    } else if (document.msExitFullscreen) {
        document.msExitFullscreen();
    } else if (document.mozCancelFullScreen) {
        document.mozCancelFullScreen();
    } else if (document.webkitExitFullscreen) {
        document.webkitExitFullscreen();
    }
}
