基於jQuery封裝的分頁組件

 

前言：

由於專案需要實現分頁效果，上jQuery外掛程式庫找了下，但是木有找到自己想要的效果，於是自己封裝了個分頁元件。

想法：

主要是初始化時基於原型建立的分頁模板然後綁定動態事件並實現刷新DOM的分頁效果。

3.元件呼叫

透過 window.pageInit= $.pageInit=pageInit 可完成分頁元件初始化。

暴露出來的介面分別為：

1.container：DOM的容器，預設.page

2.setPos：DOM放置的HTML位置，預設body

3.totalPages：預設的頁數，必填，預設null

4.totalLists：預設的資料總數，必填，預設null

5.initPage：目前頁,預設第一頁

6.inputVal：跳轉頁，預設第一頁

7.callBack：執行的回呼函數，必填，預設null

效果：

透過callBack接口，加入自己所需要執行的function函數，並且需要return true時才回執行動態的DOM渲染。
