基于jQuery的一个简单的图片查看器_html/css_WEB-ITnose
项目中自己diy了一个图片查看器。因为初始代码不是自己的，只是在上面改了一下也没有弄的很漂亮。等以后有时间了在重写一下样式和封装，作为备用的只是积累吧。如果有童鞋有用到，完全可以在此基础上改，比较容易，代码也比较简单
图片查看器主要有几个功能：
1.显示图片和图片信息（图片名称、发布者等等）
2.切换图片
3.关闭图片查看器
初始化接口函数pictureViewer.init: function(picInfos,tapNumber,isBig)
picInfos: 传入图片组信息，必须，格式如下
var picInfos = [ { "url" : "default.png", "data": [ { "key":"名称:", "value":"测试图片" }, { "key":"发布者：", "value":"chua" } ] }, { "url" : "test.jpeg", "data": [ { "key":"名称", "value":"测试图片" }, { "key":"发布者：", "value":"发大水发大水发顺风h" }, { "key":"这个图片的其他信息", "value":"vsfsgsdgfds234323424" } ] }, ... ] //传入参数的样式 tapNumber: 要显示的图片在图片列表中的索引，必须，从0开始
isBig：是否使用大图查看，默认是false，可选
html及css源码如下（后面有一个例子）

测试例子pictureViewer.init(picInfos,0,false);的效果图如下
这是一个比较粗糙的图片查看器，改起来也比较方便。后期如果有时间本人重写一下。
