原创 瀑布流插件（动态排序，滚动加载，自适应宽度）

代码很简单  有兴趣可以自行修改

你懂的：https://files.cnblogs.com/bbvi/jquery.Waterfall.zip

//watefallHeight 瀑布流高度    也可以通过$watefallHeight获得
                var watefallHeight = $("#galleryContainer").Watefall(
                {
                    itemMarginLeft: 20,//左间距
                    itemMarginTop: 20,//上间距
                    sortName: "",//排序字段
                    asc_desc:false//排序
                });
