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?

我想添加我的解决方案,与ngRepeat和过滤器,你使用它不使用$watch或切片数组。

您的筛选结果将分页!

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

app.controller('myController', ['$scope', function($scope){
    $scope.list= ['a', 'b', 'c', 'd', 'e'];

    $scope.pagination = {
        currentPage: 1,
        numPerPage: 5,
        totalItems: 0
    };

    $scope.searchFilter = function(item) {
        //Your filter results will be paginated!
        //The pagination will work even with other filters involved
        //The total number of items in the result of your filter is accounted for
    };

    $scope.paginationFilter = function(item, index) {
        //Every time the filter is used it restarts the totalItems
        if(index === 0) 
            $scope.pagination.totalItems = 0;

        //This holds the totalItems after the filters are applied
        $scope.pagination.totalItems++;

        if(
            index >= (($scope.pagination.currentPage - 1) * $scope.pagination.numPerPage)
            && index < ((($scope.pagination.currentPage - 1) * $scope.pagination.numPerPage) + $scope.pagination.numPerPage)
        )
            return true; //return true if item index is on the currentPage

        return false;
    };
}]);

在HTML中,确保在分页过滤器之前对ngRepeat应用过滤器。

<table data-ng-controller="myController">
    <tr data-ng-repeat="item in list | filter: searchFilter | filter: paginationFilter track by $index">
        <td>
            {{item}}
        </td>
    <tr>
</table>
<ul class="pagination-sm"
    uib-pagination
    data-boundary-links="true"
    data-total-items="pagination.totalItems"
    data-items-per-page="pagination.numPerPage"
    data-ng-model="pagination.currentPage"
    data-previous-text="&lsaquo;"
    data-next-text="&rsaquo;"
    data-first-text="&laquo;"
    data-last-text="&raquo;">
 </ul>

其他回答

我在这里提取了相关的部分。这是一个“没有装饰”的表格式寻呼机,所以排序或过滤不包括在内。请根据需要随意更改/添加:

//your data source may be different. the following line is //just for demonstration purposes only var modelData = [{ text: 'Test1' }, { text: 'Test2' }, { text: 'Test3' }]; (function(util) { util.PAGE_SIZE = 10; util.range = function(start, end) { var rng = []; if (!end) { end = start; start = 0; } for (var i = start; i < end; i++) rng.push(i); return rng; }; util.Pager = function(data) { var self = this, _size = util.PAGE_SIZE;; self.current = 0; self.content = function(index) { var start = index * self.size, end = (index * self.size + self.size) > data.length ? data.length : (index * self.size + self.size); return data.slice(start, end); }; self.next = function() { if (!self.canPage('Next')) return; self.current++; }; self.prev = function() { if (!self.canPage('Prev')) return; self.current--; }; self.canPage = function(dir) { if (dir === 'Next') return self.current < self.count - 1; if (dir === 'Prev') return self.current > 0; return false; }; self.list = function() { var start, end; start = self.current < 5 ? 0 : self.current - 5; end = self.count - self.current < 5 ? self.count : self.current + 5; return Util.range(start, end); }; Object.defineProperty(self, 'size', { configurable: false, enumerable: false, get: function() { return _size; }, set: function(val) { _size = val || _size; } }); Object.defineProperty(self, 'count', { configurable: false, enumerable: false, get: function() { return Math.ceil(data.length / self.size); } }); }; })(window.Util = window.Util || {}); (function(ns) { ns.SampleController = function($scope, $window) { $scope.ModelData = modelData; //instantiate pager with array (i.e. our model) $scope.pages = new $window.Util.Pager($scope.ModelData); }; })(window.Controllers = window.Controllers || {}); <script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script> <table ng-controller="Controllers.SampleController"> <thead> <tr> <th> Col1 </th> </tr> </thead> <tbody> <tr ng-repeat="item in pages.content(pages.current)" title="{{item.text}}"> <td ng-bind-template="{{item.text}}"></td> </tr> </tbody> <tfoot> <tr> <td colspan="4"> <a href="#" ng-click="pages.prev()">&laquo;</a> <a href="#" ng-repeat="n in pages.list()" ng-click="pages.current = n" style="margin: 0 2px;">{{n + 1}}</a> <a href="#" ng-click="pages.next()">&raquo;</a> </td> </tr> </tfoot> </table>

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>

概述:分页使用

 - ng-repeat
 - uib-pagination

观点:

<div class="row">
    <div class="col-lg-12">
        <table class="table">
            <thead style="background-color: #eee">
                <tr>
                    <td>Dispature</td>
                    <td>Service</td>
                    <td>Host</td>
                    <td>Value</td>
                </tr>
            </thead>
            <tbody>
                <tr ng-repeat="x in app.metricsList">
                    <td>{{x.dispature}}</td>
                    <td>{{x.service}}</td>
                    <td>{{x.host}}</td>
                    <td>{{x.value}}</td>
                </tr>
            </tbody>
        </table>

        <div align="center">
            <uib-pagination items-per-page="app.itemPerPage" num-pages="numPages"
                total-items="app.totalItems" boundary-link-numbers="true"
                ng-model="app.currentPage" rotate="false" max-size="app.maxSize"
                class="pagination-sm" boundary-links="true"
                ng-click="app.getPagableRecords()"></uib-pagination>        

            <div style="float: right; margin: 15px">
                <pre>Page: {{app.currentPage}} / {{numPages}}</pre>
            </div>          
        </div>
    </div>
</div>

JS控制器:

app.controller('AllEntryCtrl',['$scope','$http','$timeout','$rootScope', function($scope,$http,$timeout,$rootScope){

    var app = this;
    app.currentPage = 1;
    app.maxSize = 5;
    app.itemPerPage = 5;
    app.totalItems = 0;

    app.countRecords = function() {
        $http.get("countRecord")
        .success(function(data,status,headers,config){
            app.totalItems = data;
        })
        .error(function(data,status,header,config){
            console.log(data);
        });
    };

    app.getPagableRecords = function() {
        var param = {
                page : app.currentPage,
                size : app.itemPerPage  
        };
        $http.get("allRecordPagination",{params : param})
        .success(function(data,status,headers,config){
            app.metricsList = data.content;
        })
        .error(function(data,status,header,config){
            console.log(data);
        });
    };

    app.countRecords();
    app.getPagableRecords();

}]);

从Angular 1.4开始,limitTo过滤器也接受第二个可选参数begin

从文档中可以看出:

{{limitTo_expression | limitTo: limit: begin}} 开始 (可选) 字符串|数字 开始限制的索引。作为一个负索引,begin表示从输入的末尾开始的偏移量。默认值为0。

所以你不需要创建一个新的指令,这个参数可以用来设置分页的偏移量

ng-repeat="item in vm.items| limitTo: vm.itemsPerPage: (vm.currentPage-1)*vm.itemsPerPage" 

这是我的例子。选中按钮在列表中间 控制器。 配置> > >

 $scope.pagination = {total: null, pages: [], config: {count: 10, page: 1, size: 7}};

分页逻辑:

/*
     Pagination
     */
    $scope.$watch('pagination.total', function (total) {
        if(!total || total <= $scope.pagination.config.count) return;
        _setPaginationPages(total);
    });

    function _setPaginationPages(total) {
        var totalPages = Math.ceil(total / $scope.pagination.config.count);
        var pages = [];
        var start = $scope.pagination.config.page - Math.floor($scope.pagination.config.size/2);
        var finish = null;

        if((start + $scope.pagination.config.size - 1) > totalPages){
            start = totalPages - $scope.pagination.config.size;
        }
        if(start <= 0) {
            start = 1;
        }

       finish = start +  $scope.pagination.config.size - 1;
       if(finish > totalPages){
           finish = totalPages;
       }


        for (var i = start; i <= finish; i++) {
            pages.push(i);
        }

        $scope.pagination.pages = pages;
    }

    $scope.$watch("pagination.config.page", function(page){
        _setPaginationPages($scope.pagination.total);
        _getRespondents($scope.pagination.config);
    });

以及我对引导的看法

<ul ng-class="{hidden: pagination.total == 0}" class="pagination">
        <li ng-click="pagination.config.page = pagination.config.page - 1"
            ng-class="{disabled: pagination.config.page == 1}" ><a href="#">&laquo;</a></li>
        <li ng-repeat="p in pagination.pages"
            ng-click="pagination.config.page = p"
            ng-class="{active: p == pagination.config.page}"><a href="#">{{p}}</a></li>
        <li ng-click="pagination.config.page = pagination.config.page + 1"
            ng-class="{disabled: pagination.config.page == pagination.pages.length}"><a href="#">&raquo;</a></li>
    </ul >

它很有用
