本文實例為大家分享了js實現彈框效果的具體代碼，供大家參考，具體內容如下

利用display來控制彈窗的現實和隱藏

<!-- 彈出層 --><div id='popLayer'></div> <!--黑色蒙版 --><div id='popBox'> <div class='close'> X </div> <div> <!-- 內容 --> </div></div>

js：

//點擊關閉按鈕var close = document.querySelector('.close')close.onclick = function () { console.log('點擊') var popBox = document.getElementById('popBox'); var popLayer = document.getElementById('popLayer'); popBox.style.display = 'none'; popLayer.style.display = 'none';}//需要顯示時調用var popLayer = document.getElementById('popLayer');popBox.style.display = 'block';popLayer.style.display = 'block';

CSS:

/* 彈出層 */#popLayer { display: none; background-color: #000; position: absolute; top: 0; right: 0; bottom: 0; left: 0; z-index: 10; opacity: 0.6;}/*彈出層*/#popBox { display: none; background-color: #FFFFFF; z-index: 11; width: 220px; height: 300px; position: fixed; top: 0; right: 0; left: 0; bottom: 0; margin: auto;}/*關閉按鈕*/#popBox .close { width: 20px; height: 20px; border-radius: 50%; position: absolute; border: 1px solid #fff; color: #fff; text-align: center; line-height: 20px; right: 8px; top: 8px; z-index: 50;}#popBox .close a { text-decoration: none; color: #2D2C3B;}
