这是css代码,具体结构视情况而定

然后是body布局

<div id="container">
            <div class="box">
                <div class="boximg">
                    <img src=http://www.mamicode.com/"img/1.jpg">
                    <div id="mask"></div>
                </div>
            </div>
            <div class="box">
                <div class="boximg">
                    <img src=http://www.mamicode.com/"img/2.jpg">
                </div>
            </div>
            <div class="box">
                <div class="boximg">
                    <img src=http://www.mamicode.com/"img/3.jpg">
                </div>
            </div>
            <div class="box">
                <div class="boximg">
                    <img src=http://www.mamicode.com/"img/4.jpg">

            <div class="box">
                <div class="boximg">

            <div class="box">
                <div class="boximg">
                    <img src=http://www.mamicode.com/"img/6.jpg">
                </div>
            </div>
            <div class="box">
                <div class="boximg">

        </div>

图片引入多少看自己

然后引入jquery-1.8.3.js,(这里其他js文件可不可以我没试过)

最后js代码:

思路如下:

<script>
        //思路如下:  
        $(function() {
            var imgWidth = $(".box").innerWidth(); //获得每个div的宽度,包括内边距  
            var screenWidth = $(window).width(); //获得浏览器可视区域的宽度  
            var num = Math.floor(screenWidth / imgWidth); //计算一行可以放几个div  
            $("#container").css({
                "width": num * imgWidth + "px",
                "margin": "0 auto"
            }); //根据每行放的div的总长来给容器一个宽度,然后居中显示  
            function waterFlow() {
                var arr = []; //定义一个数组  
                for(var i = 0; i < $(".box").length; i++) {
                    if(i < num) { //一行显示num个div,将第一行的每个div高度写入数组  
                        arr[i] = $(".box").eq(i).innerHeight();
                    } else {
                        var minImgHeight = Math.min.apply(null, arr); //取得数组中最小高度的div  
                        var index = getMinIndex(arr, minImgHeight); //取得数组中最小高度的div的索引  
                        $(".box").eq(i).css({
                            "position": "absolute",
                            "top": minImgHeight + "px",
                            "left": $(".box").eq(index).offset().left + "px"
                        }); //瀑布流布局  
                        arr[index] += $(".box").eq(i).innerHeight(); //将布局好的该div的高度和该div上面的div高度相加,重新放入数组  
                    }
                }
            }

            function getMinIndex(arr, min) { //取得数组中最小高度的div的索引  
                for(var i in arr) {
                    if(arr[i] == min) {
                        return i;
                    }
                }
            }

            function checkScrollDirector() { //判断滚动条是否滑到底部  
                var flag = 0;
                if($(document).scrollTop() + $(window).height() >= $(document).height()) {
                    flag = 1;
                }
                return flag;
            }
            console.log($(document).height())
            console.log($(window).height())
            window.onload = function() {
                waterFlow(); //图片加载完毕执行  
                var json = {
                    "data": [{
                            "src": "img/1.jpg"

                        }, {
                            "src": "img/10.jpg"
                        },
                        {

                    ]
                };
                window.onscroll = function() { //滚动条滚动执行  
                    if(checkScrollDirector()) {
