index.html代码：

<!doctype html>
<html ng-app="app">

app.js代码：

//引入 'myModele' 模块
var app = angular.module('app', ['myModule']);

app.contriller('myCtrl', function($scope){

    //设置分页的参数
    $scope.option = {
        curr: 1,  //当前页数
        all: 20,  //总页数
        count: 10,  //最多显示的页数，默认为10

        //点击页数的回调函数，参数page为点击的页数
        click: function (page) {
            console.log(page);
            //这里可以写跳转到某个页面等...
