由于项目需要实现分页效果,上jQuery插件库找了下,但是木有找到自己想要的效果,于是自己封装了个分页组件。
主要是初始化时基于原型建立的分页模板然后绑定动态事件并实现刷新DOM的分页效果。

通过 window.pageInit= $.pageInit=pageInit 可完成分页组件初始化。
暴露出来的接口分别为:
1.container:DOM的容器,默认.page
2.setPos:DOM放置的HTML位置,默认body
3.totalPages:默认的页数,必填,默认null
4.totalLists:默认的数据总数,必填,默认null
5.initPage:当前页,默认第一页
6.inputVal:跳转页,默认第一页
7.callBack:执行的回调函数,必填,默认null

通过callBack接口,添加自己所需要执行的function函数,并且需要return true时才回执行动态的DOM渲染。
