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?

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();
}]);

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()">«</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()">»</a> </td> </tr> </tfoot> </table>
前面的消息基本上推荐了如何自己构建分页。如果你和我一样，更喜欢一个完整的指令，我刚刚发现了一个很棒的指令，叫做ngTable。它支持排序、过滤和分页。
这是一个非常干净的解决方案，你所需要的是:
<table ng-table="tableParams" class="table">
<tr ng-repeat="user in $data">
<td data-title="'Name'" sortable="'name'">
{{user.name}}
</td>
<td data-title="'Age'" sortable="'age'">
{{user.age}}
</td>
</tr>
</table>
在控制器中:
$scope.tableParams = new ngTableParams({
page: 1, // show first page
count: 10, // count per page
sorting: {
name: 'asc' // initial sorting
}
}, {
total: data.length, // length of data
getData: function($defer, params) {
// use build-in angular filter
var orderedData = params.sorting() ?
$filter('orderBy')(data, params.orderBy()) :
data;
var start = (params.page() - 1) * params.count();
var end = params.page() * params.count();
$defer.resolve(orderedData.slice( start, end));
}
});

我最近为用Angular构建的站点实现了分页。你可以签出源代码:https://github.com/angular/builtwith.angularjs.org
我会避免使用过滤器来分离页面。您应该在控制器中将这些项分解为页面。
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() {
$scope.figureOutTodosToDisplay();
};
});
引导UI组件
<pagination boundary-links="true"
max-size="3"
items-per-page="itemsPerPage"
total-items="todos.length"
ng-model="currentPage"
ng-change="pageChanged()"></pagination>
Angular UI引导-分页指令
查看UI Bootstrap的分页指令。我最终使用了它，而不是在这里发布的，因为它有足够的功能满足我目前的使用，并有一个完整的测试规范。
View
<!-- table here -->
<pagination
ng-model="currentPage"
total-items="todos.length"
max-size="maxSize"
boundary-links="true">
</pagination>
<!-- items/page select here if you like -->
控制器
todos.controller("TodoController", function($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);
});
});
