web前端————angular1表格中的复选框、全选、反选、分页小例子

html页面代码：

<table class="table  ordertable label-table">
      <thead>
        <tr>
          <th style="width:10%;">
            <input type="checkbox" ng-checked="selectAllButton()" ng-click="clickSelectAll($event)">全选
          </th>
          <th>姓名</th>
          <th>年龄</th>
        </tr>
      </thead>
      <tbody>
        <tr ng-repeat="(index,item) in list">
          <td>
            <input type="checkbox" ng-checked="itemChecked(item)" ng-click="itemCheckedClick(item)">
          </td>
          <td>
            <p>{{item.name}}</p>
          </td>
          <td>
            <p>{{item.id}}</p>
          </td>
        </tr>
      </tbody>
    </table>

JS代码：

var app = angular.module('app',[])
app.controller('myController',function($scope) {
    $scope.list = []
    $scope.testData = [//模拟后台数据
        { id:1,name:"小一"},{ id:2,name:"小二"},{ id:3,name:"小三"},{ id:4,name:"小四"},
        { id:5,name:"小五"},{ id:6,name:"小六"},{ id:7,name:"小七"},{ id:8,name:"小八"},{ id:9,name:"小九"},
        { id:10,name:"小十"},{id:11,name:"小十一"},{ id:12,name:"小十二"},{ id:13,name:"小十三"},{ id:14,name:"小十四"},{ id:15,name:"小十五"},
        { id:16,name:"小十六"},{ id:17,name:"小十七"},{ id:18,name:"小十八"},{ id:19,name:"小十九"},{ id:20,name:"小二十"},
    ]
    $scope.page = 0//页面编码
    $scope.selectArrray = []    //定义第三方变量，存储选中的数据

        $scope.list = $scope.testData.slice(page*5,num*5)

        })
