使用 ng 重复在列表上进行分页

javascript angularjs pagination

我正在尝试将页面添加到我的列表中。我遵循了AngularJS教程，这是一个关于智能手机的教程，我试图只显示一定数量的对象。这是我的html文件：

  <div class='container-fluid'>
    <div class='row-fluid'>
        <div class='span2'>
            Search: <input ng-model='searchBar'>
            Sort by: 
            <select ng-model='orderProp'>
                <option value='name'>Alphabetical</option>
                <option value='age'>Newest</option>
            </select>
            You selected the phones to be ordered by: {{orderProp}}
        </div>

        <div class='span10'>
          <select ng-model='limit'>
            <option value='5'>Show 5 per page</option>
            <option value='10'>Show 10 per page</option>
            <option value='15'>Show 15 per page</option>
            <option value='20'>Show 20 per page</option>
          </select>
          <ul class='phones'>
            <li class='thumbnail' ng-repeat='phone in phones | filter:searchBar | orderBy:orderProp | limitTo:limit'>
                <a href='#/phones/{{phone.id}}' class='thumb'><img ng-src='{{phone.imageUrl}}'></a>
                <a href='#/phones/{{phone.id}}'>{{phone.name}}</a>
                <p>{{phone.snippet}}</p>
            </li>
          </ul>
        </div>
    </div>
  </div>

我添加了一个带有一些值的选择标记，以限制将显示的项目数。我现在想要的是添加分页以显示接下来的5，10等。

我有一个控制器可以与此配合使用：

function PhoneListCtrl($scope, Phone){
    $scope.phones = Phone.query();
    $scope.orderProp = 'age';
    $scope.limit = 5;
}

而且我还有一个模块，以便从json文件中检索数据。

angular.module('phonecatServices', ['ngResource']).
    factory('Phone', function($resource){
        return $resource('phones/:phoneId.json', {}, {
            query: {method: 'GET', params:{phoneId:'phones'}, isArray:true}
        });
    });

如果您没有太多数据，则绝对可以通过将所有数据存储在浏览器中并过滤特定时间可见的内容来进行分页。

下面是一个简单的分页示例，来自 angular .js Github wiki 上的小提琴列表，这应该很有帮助：

var app=angular.module('myApp', []);

function MyCtrl($scope) {
    $scope.currentPage = 0;
    $scope.pageSize = 10;
    $scope.data = [];
    $scope.numberOfPages=function(){
        return Math.ceil($scope.data.length/$scope.pageSize);                
    }
    for (var i=0; i<45; i++) {
        $scope.data.push("Item "+i);
    }
}

//We already have a limitTo filter built-in to angular,
//let's make a startFrom filter
app.filter('startFrom', function() {
    return function(input, start) {
        start = +start; //parse to int
        return input.slice(start);
    }
});

<div ng-controller="MyCtrl">
    <ul>
        <li ng-repeat="item in data | startFrom:currentPage*pageSize | limitTo:pageSize">
            {{item}}
        </li>
    </ul>
    <button ng-disabled="currentPage == 0" ng-click="currentPage=currentPage-1">
        Previous
    </button>
    {{currentPage+1}}/{{numberOfPages()}}
    <button ng-disabled="currentPage >= data.length/pageSize - 1" ng-click="currentPage=currentPage+1">
        Next
    </button>
</div>

我复制了接受的答案，但在HTML中添加了一些Bootstrap类：

var app=angular.module('myApp', []);

function MyCtrl($scope) {
    $scope.currentPage = 0;
    $scope.pageSize = 10;
    $scope.data = [];
    $scope.numberOfPages=function(){
        return Math.ceil($scope.data.length/$scope.pageSize);                
    }
    for (var i=0; i<45; i++) {
        $scope.data.push("Item "+i);
    }
}

//We already have a limitTo filter built-in to angular,
//let's make a startFrom filter
app.filter('startFrom', function() {
    return function(input, start) {
        start = +start; //parse to int
        return input.slice(start);
    }
});
