简单写了一点分页的功能，没有注释没有完成啥都没有，只是写了一下思路..待续

<!DOCTYPE html>
<html data-ng-app="myPage">
<head>
    <title></title>
    <script src="../js/angular.min.js"></script>
</head>
<body data-ng-controller="myPageController">
<div page data-items-source="itemsSource" data-page-size="pageSize" data-current-page="currentPage"></div>
</body>
<script>
    var myPage = angular.module(‘myPage‘, []);
    myPage.controller(‘myPageController‘, function ($scope) {
        $scope.itemsSource = [
            {
                Id: 1,
                name: ‘Jackey1‘
            },
            {
                Id: 2,
                name: ‘Jackey2‘
            },
            {

<style>

        border: 1px solid gray;
        line-height: 20px;
        text-align: center;
        float: left;
        margin-left: 15px;
        cursor: pointer;
    }

    .pageBox:hover {
        background: yellow;;
    }

    .prevBtn {
        width: 50px;
        height: : 20 px;
        float: left;
        cursor: pointer;
        border: 1px solid gray;
        text-align: center;
        line-height: 20px;
    }

    .nextBtn {
        width: 50px;
        height: 20px;
        float: left;
        cursor: pointer;
        border: 1px solid gray;
        margin-left: 10px;
        text-align: center;
        line-height: 20px;
    }
</style>
</html>

templateUrl

<div class="page">
<div class="prevBtn" data-ng-click="prevClick()">prev</div>
<div class="pageBox" data-ng-repeat="item in pageBoxArray" data-ng-click="showPage(item)">{{item}}</div>
<div class="nextBtn" data-ng-click="nextClick()">next</div>
    </div>

后期想实现的功能是，直接给page的directive数据源和需要显示的条数，directive提供接口返回当前页的数据，然后再把数据给另外一个显示数据的direcive绑定到模板上...
