具体代码如下

html部分:

<!DOCTYPE html>

 </ul>
 <div class="backward">
 <span></span>
 </div>
 <script src="./js/jquery.min.js"></script>
 <script src="./js/index.js"></script>
 <script>
 
 </script>

index.css部分

body{
 width: 100%;
 height: 100%;
 background-image: url(../images/bj.jpg);
 background-repeat: no-repeat;
 background-size: cover;
 position: relative;
}
.redPaper{
 width: 100%;
 height: 100%;
 /* border: 1px solid black; */
 overflow: hidden;
}
.redPaper li {
 position: absolute;
 animation: all 3s linear;
 top:-100px;
 -webkit-tap-highlight-color: rgba(0, 0, 0, 0);
}
.redPaper li a{
 display: block;
}
.backward{
 width: 100%;
 background:#ccc;
 opacity: 0.5;
 position: absolute;
 top: 0;
 
}
.backward span{
 display: inline-block;
 width: 100px;
 height: 100px;
 color: #000;
 font-weight: bold;
 position: absolute;
 top: 0;
 left: 0;
 right: 0;
 bottom: 0;
 margin: auto;
 text-align: center;
 line-height: 100px;
 font-size: 1000%;
}

index.js部分:

$(document).ready(function () {
 var win = (parseInt($('.redPaper').css('width'))) - 60;
 console.log(win)
 $(".redPaper").css("height", $(document).height());
 $(".backward").css("height", $(document).height());
 $("li").css({});
 // 点击确认的时候关闭模态层
 // $(".sen a").click(function(){
 // $(".mo").css("display", "none")
 // });

 var del = function () {
 nums++;
 // console.info(nums);
 // console.log($(".li" + nums).css("left"));
 $(".li" + nums).remove();
 setTimeout(del, 200)
 }

 var addRedPaper = function () {
 var hb = parseInt(Math.random() * (3 - 1) + 1);
 var randomW = parseInt(Math.random() * (70 - 30) + 20);
 var randomLeft = parseInt(Math.random() * win);
 var randomRotate = (parseInt(Math.random() * 45)) + 'deg';
 // console.log(rot)
 num++;
 $(".redPaper").append("<li class='li" + num + "' ><a href='javascript:;'><img src='images/hb_" + hb + ".png' data-num ='" + num + "'></a></li>");
 $(".li" + num).css({
 "left": randomLeft,
 });
 $(".li" + num + " a img").css({
 "width": randomW,
 "transform": "rotate(" + randomRotate + ")",
 "-webkit-transform": "rotate(" + randomRotate + ")",
 "-ms-transform": "rotate(" + randomRotate + ")", /* Internet Explorer */
 "-moz-transform": "rotate(" + randomRotate + ")", /* Firefox */
 "-webkit-transform": "rotate(" + randomRotate + ")",/* Safari 和 Chrome */
 "-o-transform": "rotate(" + randomRotate + ")" /* Opera */
 });
 $(".li" + num).animate({ 'top': $(window).height() + 20 }, 5000, function () {
 //删掉已经显示的红包
 this.remove()
 });
 //点击红包的时候弹出模态层
 $(".li" + num).click(function (e) {
 if (e.target.tagName == 'IMG') {
 console.log(e.target.dataset.num)
 }

 });
 setTimeout(addRedPaper, 200)
 }

 //增加红包
 var num = 0;
 setTimeout(addRedPaper, 3000);

 //倒数计时
 var backward = function () {
 numz--;
 if (numz > 0) {
 $(".backward span").html(numz);
 } else {
 $(".backward").remove();
 }
 setTimeout(backward, 1000)

 }

 var numz = 4;
 backward();

})
