本文例項為大家分享了js實現移動端紅包雨頁面的具體程式碼，供大家參考，具體內容如下
實習的效果如下：
具體程式碼如下
html部分：
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width,initial-scale=1.0"> <meta http-equiv="X-UA-Compatible" content="ie=edge"> <title>紅包雨</title> <link rel="stylesheet" href="./css/demo.css" > <link rel="stylesheet" href="./css/index.css" > </head> <body> <!-- 紅包 --> <ul class="redPaper"> <!-- <li> <a href="#" rel="external nofollow" ><img src="./images/hb_1.png" alt="javascript實現移動端紅包雨頁面"></a> </li> --> </ul> <div class="backward"> <span></span> </div> <script src="./js/jquery.min.js"></script> <script src="./js/index.js"></script> <script> </script> </body> </html>
demo.css為初始化css,可以不加
index.css部分

//倒數計時
