前言：
由於項目需要實現分頁效果，上jQuery插件庫找了下，但是木有找到自己想要的效果，於是自己封裝了個分頁組件。
備注：最新修改會先在GitHub同步：

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

3.組件調用
通過 window.pageInit= $.pageInit=pageInit 可完成分頁組件初始化。
暴露出來的接口分別為：
1.container：DOM的容器，默認.page
2.setPos：DOM放置的HTML位置，默認body
3.totalPages：默認的頁數，必填，默認null
4.totalLists：默認的數據總數，必填，默認null
5.initPage：當前頁,默認第一頁
6.inputVal：跳轉頁，默認第一頁
7.callBack：執行的回調函數，必填，默認null
1 <!DOCTYPE html> 2 <html> 3 <head lang="en"> 4 <meta charset="UTF-8"> 5 <title>基於jQuery封裝的分頁組件</title> 6 <link rel="stylesheet" href="css/page.init.css"> 7 </head> 8 <body> 9 <script src="https://cdn.bootcss.com/jquery/2.2.4/jquery.js"></script> 10 <script src="js/pageInit.js"></script> 11 <script> 12 $.pageInit( 13 { 14 container:'.page',//容器：默認page 15 //setPos:'body',//放置位置：默認body 16 totalPages:10,//總頁數：必填 17 totalLists:100,//數據總數：必填 18 initPage:1,//初始頁碼：默認1 19 inputVal:1,//設置跳轉的input值：默認1 20 //要執行的函數：默認null，必須為fn且返回true則可執行分頁，false則不執行 21 callBack:function(n){ 22 var flag=true; 23 console.log(n); 24 return flag; 25 } 26 } 27 ); 28 </script> 29 </body> 30 </html>
效果：
通過callBack接口，添加自己所需要執行的function函數，並且需要return true時才回執行動態的DOM渲染。
