分页插件，直接把返回值赋过去即可

结构：
<!DOCTYPE html>
<html>

  <head>
    <meta charset="utf-8" />
    <title></title>
    <style>
      * {
        padding: 0;
        margin: 0;
      }
      
      .page_div {
        margin-top: 20px;

        display: inline-block;
      }
      
      #firstPage,

  <script src="http://www.jq22.com/jquery/jquery-1.10.2.js"></script>
  <script type="text/javascript" src="js/paging.js"></script>
  <script>
    //分页
    $("#page").paging({

    // 模拟ajax数据用以下方法，方便用户更好的掌握用法

　封装好的js:

(function($, window, document, undefined) {
  //定义分页类
  function Paging(element, options) {
    this.element = element;
    //传入形参
    this.options = {
      pageNo: options.pageNo || 1,
      totalPage: options.totalPage,
      totalSize: options.totalSize,
      callback: options.callback
    };
    //根据形参初始化分页html和css代码
    this.init();
  }
  //对Paging的实例对象添加公共的属性和方法
  Paging.prototype = {
    constructor: Paging,
    init: function() {
      this.creatHtml();
      this.bindEvent();
    },
    creatHtml: function() {
