<button>关灯</button>
    <script>
        var btn = document.querySelector('button');
        var bd = document.querySelector('body');
        btn.onclick = function () {
            if (btn.innerHTML === '关灯') {
                bd.style.backgroundColor = '#111';
                btn.innerHTML = '开灯';
            }
            else {
                bd.style.backgroundColor = '#fff';
                btn.innerHTML = '关灯';
