demo.css为初始化css,可以不加
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();})
