简单分页插件simplePagination改造为CMD模块
说明
简单分页simplePagination的官网地址
http://flaviusmatis.github.io/simplePagination.js/
这个是基于jquery的插件形式，为了适用于CMD规范下的开发，比如方便seajs引用，将simplePagination改造成一个符合CMD规范的模块。
示例
下面是在一个项目中的组件调用改造后的simplePagination的例子
List.prototype.initPagebar = function(itemsCount) {
var me = this;
var pagination = me.pagination;
// 1：有数据；0：无数据
var t1 = itemsCount > 0 ? '1' : '0';
// 1：未销毁，0：已销毁 （指的是pagination是否调用destroy，默认初始化后wrapper.children().length为1）
var t2 = pagination.wrapper.children().length > 0 ? '1' : '0';
// 1：第一页，0：非第一页
var t3 = me.pageNo == 1 ? '1' : '0';
var t = t1 + t2 + t3;
switch (t) {
// 有数据，未销毁，非第一页。更新总数目。
// 有数据，已销毁，第一页。更新总数目。
case '110':
case '101':
pagination.updateItems(itemsCount);
break;
// 有数据，未销毁，第一页。更新总数目，设为第一页。
case '111':
pagination.updateItems(itemsCount);
pagination.drawPage(1);
break;
// 无数据，未销毁，不论是否第一页。销毁。
case '011':
case '010':
pagination.destroy();
break;
}
