  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)

  js的源码如下

  css中用到的切图imgTap.png为下面的图片

  

  测试例子pictureViewer.init(picInfos,0,true);的效果图如下

  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。
