前言
KISSY 是由阿里集团前端工程师们发起创建的一个开源 JS 框架。它具备模块化、高扩展性、组件齐全,接口一致、自主开发、适合多种应用场景等特性。本人在一次项目中层使用这个uploader组件。
关于kissy uploader:
Uploader是非常强大的异步文件上传组件,支持ajax、iframe、flash三套方案,实现浏览器的全兼容,调用非常简单,内置多套主题支持和常用插件,比如验证、图片预览、进度条等。
广泛应用于淘宝网,比如退款系统、爱逛街、二手、拍卖、我的淘宝、卖家中心、导购中心等。
拥有非常不错的扩展性,可以自己定制主题和插件。
Kissy uploader配置简单而且使用方便,官网提供许多主题稍加修改便可用于项目当中,本文的案例采用的是kissy uploader的在线js库。更多的资料大家可以去官网:http://gallery.kissyui.com/uploader/1.4/guide/index.html#demo汇总查找相关资料,讲述的很全面。
案例截图
相关配置
1、本文照片的相关信息我采用EF coder first将其保存在数据库中了,相关代码
实体类:
[Table("Photos")] public class Photos { [Key] public int ID { get; set; } public string Name { get; set; } public string Desc { get; set; } public string Src { get; set; } public DateTime? PubliseTime { get; set; } }
数据库上下文:
public class PhotoDB:DbContext { public PhotoDB() : base("name=PhotoDB") { } public DbSet<Photos> Photos { get; set; } }
连接字符串:
<connectionStrings> <add name="PhotoDB" connectionString="server=(local);Initial Catalog=Photo;Integrated Security=SSPI" providerName="System.Data.SqlClient" /> </connectionStrings>
2、上传图片配置(相关配置说明大家可以参考官网示例)
上传页面index:
<!doctype html> <html> <head> <meta charset="utf-8"/> <script src="http://a.tbcdn.cn/s/kissy/1.3.0/kissy-min.js" charset="utf-8"></script> <style type="text/css"> .textvalue{padding: 0;width: 118px;border-top: 1px solid #E2E2E2;height: 25px;} .sub{height:30px; width:120px;position:relative;top:30px;} </style> </head> <body> @using (Html.BeginForm()) { <div class="grid"> <input type="file" class="g-u" id="J_UploaderBtn" value="上传图片" name="Filedata" /> <input type="hidden" id="J_Urls" name="urls" value="" /> <div class="g-u">还可以上传<span id="J_UploadCount">14</span>张图片</div> </div> <ul id="J_UploaderQueue" class="grid"> <script type="text/uploader-theme"> <li id="queue-file-{id}" class="g-u" data-name="{name}" style="height: 140px !important"> <div class="pic"> <a href="javascript:void(0);"><img class="J_Pic_{id} preview-img" src="" /></a> </div> <div class=" J_Mask_{id} pic-mask"></div> <div class="status-wrapper"> <div class="status waiting-status"><p>等待上传,请稍候</p></div> <div class="status start-status progress-status success-status"> <div class="J_ProgressBar_{id}"><s class="loading-icon"></s>上传中...</div> </div> <div class="status error-status"> <p class="J_ErrorMsg_{id}">上传失败,请重试!</p> </div> </div> <a class="J_Del_{id} del-pic" href="#">删除</a> <input type="text" value="" name="desc" id="desc" class="textvalue" placeholder="描述"> </li> </script> </ul> <input type="submit" value="保存" class="sub" /> } <script type="text/javascript"> var S = KISSY; if (S.Config.debug) { var srcPath = "../../../../"; S.config({ packages: [ { name: "gallery", path: srcPath, charset: "utf-8" } ] }); } var $ = S.Node.all; S.use(‘gallery/uploader/1.4/index,gallery/uploader/1.4/themes/imageUploader/index,gallery/uploader/1.4/themes/imageUploader/style.css‘, function (S, Uploader, ImageUploader) { //上传插件 var plugins = ‘gallery/uploader/1.4/plugins/auth/auth,‘ + ‘gallery/uploader/1.4/plugins/urlsInput/urlsInput,‘ + ‘gallery/uploader/1.4/plugins/proBars/proBars,‘ + ‘gallery/uploader/1.4/plugins/filedrop/filedrop,‘ + ‘gallery/uploader/1.4/plugins/preview/preview‘; S.use(plugins, function (S, Auth, UrlsInput, ProBars, Filedrop, Preview) { var uploader = new Uploader(‘#J_UploaderBtn‘, { //处理上传的服务器端脚本路径 action: "/Home/PictureUpload", multiple: true }); //上传成功后显示图片描述 uploader.on(‘success‘, function (ev) { var result = ev.file.result; if (result.desc) { var $desc = $(‘.J_Desc_‘ + ev.file.id); $desc.html(result.desc); } }) //使用主题 uploader.theme(new ImageUploader({ queueTarget: ‘#J_UploaderQueue‘ })) //验证插件 .plug(new Auth({ //最多上传个数 max: 14, //图片最大允许大小 maxSize: 2000 })) //url保存插件 .plug(new UrlsInput({ target: ‘#J_Urls‘ })) //进度条集合 .plug(new ProBars()) //拖拽上传 .plug(new Filedrop()) //图片预览 .plug(new Preview()) ; //渲染默认数据 uploader.restore(); }); }) </script> </body> </html>
后台临时保存方法:
//图片上传处理
public ActionResult PictureUpload()
{
//保存到临时文件
HttpPostedFileBase postedfile = Request.Files["Filedata"];
var filename = postedfile.FileName;
var newname =Guid.NewGuid()+filename.Substring(filename.LastIndexOf(‘.‘));
var filepath = Server.MapPath("/UpLoad/temp/") + newname;
Image image = Image.FromStream(postedfile.InputStream, true);
image.Save(filepath);//保存为图片
return Json(new { status = 1, url = "/UpLoad/temp/" + newname });
}
表单提交保存数据相关方法:
[HttpPost]
public ActionResult Index(string urls, FormCollection fc)
{
var urlArray = urls.Split(‘,‘);
var desArray = fc["desc"].Split(‘,‘);
for (int i = 0; i <desArray.Length; i++)
{
//保存为正式文件
var filename = urlArray[i].Substring(urlArray[i].LastIndexOf(‘/‘) + 1);
var oldfile = Server.MapPath(urlArray[i]);
var newfile = Server.MapPath("/UpLoad/photo/")+filename;
System.IO.File.Move(oldfile, newfile);
db.Photos.Add(
new Photos { Name = filename, Desc = desArray[i], Src = "/UpLoad/photo/"+filename, PubliseTime = DateTime.Now }
);
}
db.SaveChanges();
return View();
}
3、瀑布流照片墙
后台返回所有照片实体类传递给视图;
//照片墙
public ActionResult Photo()
{
var photos = db.Photos.ToList();
return View(photos);
}
前台动态加载图片js及照片墙页面:
@model List<MvcApplication3.Models.Photos>
@{Layout = null;}

});
//window resize
var currentWidth = 1100;
$(window).resize(function () {
var winWidth = $(window).width();
var conWidth;
if (winWidth < 660) {
conWidth = 440;
col = 2
} else if (winWidth < 880) {
conWidth = 660;
col = 3
} else if (winWidth < 1100) {
conWidth = 880;
col = 4;
} else {
conWidth = 1100;
col = 5;
}
if (conWidth != currentWidth) {
currentWidth = conWidth;
$(‘#container‘).width(conWidth);
$(‘#container‘).BlocksIt({
numOfCol: col,

}
});
});
</script>
</head>
<body>

}
<!---->

瀑布流采用国外的一个jquery插件实现。
结语
本人强烈推荐采用kissy uploader上传插件,原因在于:采用的上传方案,当值是数组时,比如“type” : ["flash","ajax","iframe"],按顺序获取浏览器支持的方式,该配置会优先使用flash上传方式,如果浏览器不支持flash,会降级为ajax,如果还不支持ajax,会降级为iframe;当值是字符串时,比如“type” : “ajax”,表示只使用ajax上传方式。这种方式比较极端,在不支持ajax上传方式的浏览器会不可用;当“type” : “auto”,auto是一种特例,等价于["ajax","iframe"]。这一点很重要,由于以前一个项目采用flash上传,当遇到移动设备时发现不支持上传了,采用该插件则不会出现此问题。
