我在内存中有大约1000项的数据集,并试图创建一个寻呼机 这个数据集,但我不确定怎么做。

我正在使用一个自定义过滤器函数来过滤结果,这工作得很好,但我需要以某种方式获得页数。

有线索吗?

Angular UI引导-分页指令

查看UI Bootstrap的分页指令。我最终使用了它,而不是在这里发布的,因为它有足够的功能满足我目前的使用,并有一个完整的测试规范。

View

<!-- table here -->

<pagination 
  ng-model="currentPage"
  total-items="todos.length"
  max-size="maxSize"  
  boundary-links="true">
</pagination>

<!-- items/page select here if you like -->

控制器

todos.controller("TodoController", function($scope) {
   $scope.filteredTodos = []
  ,$scope.currentPage = 1
  ,$scope.numPerPage = 10
  ,$scope.maxSize = 5;

  $scope.makeTodos = function() {
    $scope.todos = [];
    for (i=1;i<=1000;i++) {
      $scope.todos.push({ text:"todo "+i, done:false});
    }
  };
  $scope.makeTodos(); 

  $scope.$watch("currentPage + numPerPage", function() {
    var begin = (($scope.currentPage - 1) * $scope.numPerPage)
    , end = begin + $scope.numPerPage;

    $scope.filteredTodos = $scope.todos.slice(begin, end);
  });
});

遗留版本:

View

<!-- table here -->

<div data-pagination="" data-num-pages="numPages()" 
  data-current-page="currentPage" data-max-size="maxSize"  
  data-boundary-links="true"></div>

<!-- items/page select here if you like -->

控制器

todos.controller("TodoController", function($scope) {
   $scope.filteredTodos = []
  ,$scope.currentPage = 1
  ,$scope.numPerPage = 10
  ,$scope.maxSize = 5;

  $scope.makeTodos = function() {
    $scope.todos = [];
    for (i=1;i<=1000;i++) {
      $scope.todos.push({ text:"todo "+i, done:false});
    }
  };
  $scope.makeTodos(); 

  $scope.numPages = function () {
    return Math.ceil($scope.todos.length / $scope.numPerPage);
  };

  $scope.$watch("currentPage + numPerPage", function() {
    var begin = (($scope.currentPage - 1) * $scope.numPerPage)
    , end = begin + $scope.numPerPage;

    $scope.filteredTodos = $scope.todos.slice(begin, end);
  });
});

其他回答

我更新了斯科特的情况。NET的plunkr http://plnkr.co/edit/FUeWwDu0XzO51lyLAEIA?p=preview,这样它就可以使用angular、angular-ui和bootstrap的新版本。

控制器

var todos = angular.module('todos', ['ui.bootstrap']);

todos.controller('TodoController', function($scope) {
  $scope.filteredTodos = [];
  $scope.itemsPerPage = 30;
  $scope.currentPage = 4;

  $scope.makeTodos = function() {
    $scope.todos = [];
    for (i=1;i<=1000;i++) {
      $scope.todos.push({ text:'todo '+i, done:false});
    }
  };

  $scope.figureOutTodosToDisplay = function() {
    var begin = (($scope.currentPage - 1) * $scope.itemsPerPage);
    var end = begin + $scope.itemsPerPage;
    $scope.filteredTodos = $scope.todos.slice(begin, end);
  };

  $scope.makeTodos(); 
  $scope.figureOutTodosToDisplay();

  $scope.pageChanged = function() {
    $scope.figureOutTodosToDisplay();
  };

});

引导UI组件

 <pagination boundary-links="true" 
    max-size="3" 
    items-per-page="itemsPerPage"
    total-items="todos.length" 
    ng-model="currentPage" 
    ng-change="pageChanged()"></pagination>

我希望我能发表评论,但我不得不在这里留下这个:

苏格兰狗。NET的答案和user2176745对后续版本的重做都很棒,但它们都遗漏了我的AngularJS (v1.3.15)版本的一些问题:

i在$scope.makeTodos中没有定义。

因此,用这个函数替换可以修复它在最近的angular版本中的问题。

$scope.makeTodos = function() {
    var i;
    $scope.todos = [];
    for (i=1;i<=1000;i++) {
        $scope.todos.push({ text:'todo '+i, done:false});
    }
};

对于那些发现像我一样很难为一个表创建分页器的人,我发布了这个。 所以,在你看来:

          <pagination total-items="total" items-per-page="itemPerPage"    ng-model="currentPage" ng-change="pageChanged()"></pagination>    
        <!-- To specify your choice of items Per Pages-->
     <div class="btn-group">
                <label class="btn btn-primary" ng-model="radioModel"  btn-radio="'Left'" data-ng-click="setItems(5)">5</label>
                <label class="btn btn-primary" ng-model="radioModel" btn-radio="'Middle'" data-ng-click="setItems(10)">10</label>
                <label class="btn btn-primary" ng-model="radioModel" btn-radio="'Right'" data-ng-click="setItems(15)">15</label>
            </div>
     //And don't forget in your table:
      <tr data-ng-repeat="p in profiles | offset: (currentPage-1)*itemPerPage | limitTo: itemPerPage" >

在你的angularJs中:

  var module = angular.module('myapp',['ui.bootstrap','dialogs']);
  module.controller('myController',function($scope,$http){
   $scope.total = $scope.mylist.length;     
   $scope.currentPage = 1;
   $scope.itemPerPage = 2;
   $scope.start = 0;

   $scope.setItems = function(n){
         $scope.itemPerPage = n;
   };
   // In case you can replace ($scope.currentPage - 1) * $scope.itemPerPage in <tr> by "start"
   $scope.pageChanged = function() {
        $scope.start = ($scope.currentPage - 1) * $scope.itemPerPage;
            };  
});
   //and our filter
     module.filter('offset', function() {
              return function(input, start) {
                start = parseInt(start, 10);
                return input.slice(start);
              };
            });     

jQuery Mobile angular适配器有一个分页过滤器,你可以基于它。

下面是一个使用它的演示小提琴(添加超过5个项目,它就会变成页面):http://jsfiddle.net/tigbro/Du2DY/

来源如下:https://github.com/tigbro/jquery-mobile-angular-adapter/blob/master/src/main/webapp/utils/paging.js

你可以很容易地使用Bootstrap UI指令做到这一点。

这个答案是对@Scotty给出的答案的修改。NET,我已经更改了代码,因为<pagination>指令现在已弃用。

下面的代码生成分页:

<ul uib-pagination 
    boundary-links="true"  
    total-items="totalItems"  
    items-per-page="itemsPerPage"  
    ng-model="currentPage"  
    ng-change="pageChanged()"  
    class="pagination"  
    previous-text="&lsaquo;"  
    next-text="&rsaquo;"  
    first-text="&laquo;"  
    last-text="&raquo;">
</ul>

为了让它发挥作用,在你的控制器中使用这个:

$scope.filteredData = []
$scope.totalItems = $scope.data.length;
$scope.currentPage = 1;
$scope.itemsPerPage = 5;

$scope.setPage = function (pageNo) {
    $scope.currentPage = pageNo;
};

$scope.pageChanged = function() {
    var begin = (($scope.currentPage - 1) * $scope.itemsPerPage)
    , end = begin + $scope.itemsPerPage;

    $scope.filteredData = $scope.data.slice(begin, end);
};

$scope.pageChanged();
