由于最近的一个项目使用的是angularjs1.0的版本，涉及到分页查询数据的功能，后来自己就用自定义指令实现了该功能。现在单独做了个简易的小demo，主要是为了分享自己写的分页功能。注：本实例调用的是真实接口数据。

首先、小demo的目录结构如下：

一、代码部分

下面直接把每一个文件的代码贴出来，重点是ListCtrl.js和pageDirective.js：

1、index.html

<!DOCTYPE html>
<html lang="en" ng-app="app" ng-cloak>
<head>
  <meta charset="UTF-8">
  <title>Title</title>
  <!--<script src="lib/jquery.js"></script>-->
  <script src="lib/angular.js"></script>
  <script src="lib/angular-ui-router.js"></script>
  <style>
    * {
      margin: 0;
      padding: 0;
    }
    .left-menu {
      width: 200px;
      float: left;
      height: 100%;
    }
    .left-menu ul {
      list-style: none;
    }
    .left-menu ul li {
      height: 40px;
      line-height: 40px;
      background-color: #777;
      color: #ddd;
      margin-bottom: 5px;
      cursor: pointer;
    }
    .main {
      margin-left: 200px;
      padding: 10px;
    }
    .left-menu ul li.active {
      background-color: #333;
      color: #fff;
    }
  </style>
</head>
<body>
  <p style="width: 100%;height: 50px;background-color: #ddd;">顶部区域</p>
  <p class="left-menu" ng-controller="MenuCtrl">
    <ul>
      <li ng-click="goState(&#39;home&#39;)" ng-class="{active:curUrl == &#39;/home&#39;}">首页</li>
      <li ng-click="goState(&#39;list&#39;)" ng-class="{active:curUrl == &#39;/list&#39;}">列表</li>
    </ul>
  </p>
  <p class="main" ui-view="main"></p>
<script src="scripts/app.js"></script>
<script src="scripts/router.js"></script>
<script src="scripts/controllers/MenuCtrl.js"></script>
<script src="scripts/controllers/ListCtrl.js"></script>
<script src="scripts/controllers/HomeCtrl.js"></script>

2、views/list.html （重要，列表数据的html部分）

<style>
  table {
    border: 1px solid #000;
    border-collapse: collapse;
    width: 100%;
  }
  table th,table td {
    border: 1px solid #000;
    text-align: center;
    height: 30px;
  }
</style>
<table>
  <thead>
  <th>ID</th>
  <th>昵称</th>
  <th>创建时间</th>
  </thead>
  <tbody>
  <tr ng-repeat="item in listData">
    <td>{{item.id}}</td>
    <td>{{item.nickname}}</td>
    <td>{{item.create_time}}</td>
  </tr>
  </tbody>
</table>
<p>
  <!--分页指令-->
  <p page-directive page-config="pageConfig"></p>
