     ul class="redPaper">
     !-- li>
     a href="#" >
    img src="./images/hb_1.png" alt="">
    /a>
     /li>
     -->
     /ul>
     div class="backward">
     span>
    /span>
     /div>
     script src="./js/jquery.min.js">
    /script>
     script src="./js/index.js">

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;

     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();
}
    )
