一、pic1.html页面代码如下:

<!DOCTYPE html><html><head>    <meta charset="UTF-8">    <title>瀑布流布局与无限加载图片相册</title>    <style type="text/css">        * {            margin: 0;            padding: 0;        }        body {            background: url(../img/bg5.jpg);        }        #items {            width: 1060px;            margin: 0 auto;            border: 1px solid lightpink;        }        .item {            border: 1px solid lightpink;            width: 200px;            color: purple;            font-size: 30px;            font-weight: bolder;            margin: 5px;            text-align: center;            opacity: 0.8;        }        img {            width: 200px;        }    </style></head><body>    <div id="items">        <p class="item"><img src="img/1.jpg" />picture-1</p>        <p class="item"><img src="img/2.jpg" />picture-2</p>        <p class="item"><img src="img/3.jpg" />picture-3</p>        <p class="item"><img src="img/4.jpg" />picture-4</p>        <p class="item"><img src="img/5.jpg" />picture-5</p>        <p class="item"><img src="img/6.jpg" />picture-6</p>        <p class="item"><img src="img/7.jpg" />picture-7</p>        <p class="item"><img src="img/8.jpg" />picture-8</p>        <p class="item"><img src="img/9.jpg" />picture-9</p>        <p class="item"><img src="img/10.jpg" />picture-10</p>        <p class="item"><img src="img/11.jpg" />picture-11</p>        <p class="item"><img src="img/12.jpg" />picture-12</p>        <p class="item"><img src="img/13.jpg" />picture-13</p>        <p class="item"><img src="img/14.jpg" />picture-14</p>        <p class="item"><img src="img/15.jpg" />picture-15</p>        <p class="item"><img src="img/16.jpg" />picture-16</p>        <p class="item"><img src="img/17.jpg" />picture-17</p>        <p class="item"><img src="img/18.jpg" />picture-18</p>        <p class="item"><img src="img/19.jpg" />picture-19</p>        <p class="item"><img src="img/20.jpg" />picture-20</p>    </div>    <a href="Handler1.ashx" id="next">下一页</a>    <script src="js/jquery-3.1.1.js" type="text/javascript" charset="utf-8"></script>    <!--插件的引用-->    <script src="js/masonry.pkgd.min.js" type="text/javascript"></script>    <script src="js/imagesloaded.pkgd.min.js" type="text/javascript" charset="utf-8"></script>    <script src="js/jquery.infinitescroll.min.js"></script>    <script>        //此方法用来初始化图片(图片全部加载完成时调用)        var init = function () {            imagesLoaded(document.querySelector(#items), function (instance) {                //此方法用来设置瀑布流布局                var msnry = new Masonry("#items", {                    itemSelector: ".item",                    columnWidth: 0 //列与列之间的宽度                });                //alert(‘所有的图片都加载完成了‘);            });        }        init();        var num = 0;        //此方法是无限加载的方法        $("#items").infinitescroll({            navSelector: "#next",            nextSelector: "a#next",            itemSelector: ".item",            debug: true,            dataType: "json",            maxPage: 10,            appendCallback: false,            path: function (index) {                console.log(index);                return "Handler1.ashx?page=" + index;            }        }, function (data) {            num -= 20;            for (var i = 0; i < data.length; i++) {                $("<p class=‘item‘><img src=http://www.mamicode.com/‘img/" + (data[i].imgUrl + num) + ".jpg‘ />" + data[i].Name + "</p>").appendTo("#items")                console.log(data[i].imgUrl + "--" + data[i].Name);            }            init();        });    </script></body></html>

二、模拟数据库数据的实体类Photoes.cs代码如下:

using System;using System.Collections.Generic;using System.Linq;using System.Web;namespace 瀑布流布局与无限加载图片相册{    public class Photoes    {        public int imgUrl { get; set; }        public string Name { get; set; }        //模拟数据库有两百条数据        public static List<Photoes> GetData()        {            List<Photoes> list = new List<Photoes>();            Photoes pic = null;            for (int i= 21; i <=200; i++)            {                pic = new Photoes();                pic.imgUrl = i;                pic.Name = "Picture-" + i;                list.Add(pic);            }            return list;        }    }}

三、服务器返回数据给客户端的一般处理程序Handler1.ashx代码如下:

using System;using System.Collections.Generic;using System.Linq;using System.Web;using System.Web.Script.Serialization;namespace 瀑布流布局与无限加载图片相册{    /// <summary>    /// 服务器返回数据给客户端的一般处理程序    /// </summary>    public class Handler1 : IHttpHandler    {        public void ProcessRequest(HttpContext context)        {            context.Response.ContentType = "text/plain";            List<Photoes> result = Photoes.GetData();            int pageIndex = Convert.ToInt32(context.Request["page"]);            var filtered = result.Where(p => p.imgUrl >= pageIndex * 20 - 19 && p.imgUrl <= pageIndex * 20).ToList();            JavaScriptSerializer ser = new JavaScriptSerializer();            string jsonData =http://www.mamicode.com/ ser.Serialize(filtered);            context.Response.Write(jsonData);        }        public bool IsReusable        {            get            {                return false;            }        }    }}

总结:前段时间学习了瀑布流布局与图片加载等知识,做了一个简单的示例,希望能巩固一下自己所学的知识。

   不断总结,不断巩固,不断提升。。。
