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
};
$http.get("allRecordPagination",{params : param})
.success(function(data,status,headers,config){
app.metricsList = data.content;
})
.error(function(data,status,header,config){
console.log(data);
});
};
app.countRecords();
app.getPagableRecords();
}]);
其他回答
我希望我能发表评论，但我不得不在这里留下这个:
苏格兰狗。NET的答案和user2176745对后续版本的重做都很棒，但它们都遗漏了我的AngularJS (v1.3.15)版本的一些问题:
i在$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++) {
$scope.todos.push({ text:'todo '+i, done:false});
}
};
ng-repeat分页
<div ng-app="myApp" ng-controller="MyCtrl">
<input ng-model="q" id="search" class="form-control" placeholder="Filter text">
<select ng-model="pageSize" id="pageSize" class="form-control">
<option value="5">5</option>
<option value="10">10</option>
<option value="15">15</option>
<option value="20">20</option>
</select>
<ul>
<li ng-repeat="item in data | filter:q | startFrom:currentPage*pageSize | limitTo:pageSize">
{{item}}
</li>
</ul>
<button ng-disabled="currentPage == 0" ng-click="currentPage=currentPage-1">
Previous
</button>
{{currentPage+1}}/{{numberOfPages()}}
<button ng-disabled="currentPage >= getData().length/pageSize - 1" ng- click="currentPage=currentPage+1">
Next
</button>
</div>
<script>
var app=angular.module('myApp', []);
app.controller('MyCtrl', ['$scope', '$filter', function ($scope, $filter) {
$scope.currentPage = 0;
$scope.pageSize = 10;
$scope.data = [];
$scope.q = '';
$scope.getData = function () {
return $filter('filter')($scope.data, $scope.q)
}
$scope.numberOfPages=function(){
return Math.ceil($scope.getData().length/$scope.pageSize);
}
for (var i=0; i<65; i++) {
$scope.data.push("Item "+i);
}
}]);
app.filter('startFrom', function() {
return function(input, start) {
start = +start; //parse to int
return input.slice(start);
}
});
</script>
对于那些发现像我一样很难为一个表创建分页器的人，我发布了这个。 所以，在你看来:
<pagination total-items="total" items-per-page="itemPerPage" ng-model="currentPage" ng-change="pageChanged()"></pagination>
<!-- To specify your choice of items Per Pages-->
<div class="btn-group">
<label class="btn btn-primary" ng-model="radioModel" btn-radio="'Left'" data-ng-click="setItems(5)">5</label>
<label class="btn btn-primary" ng-model="radioModel" btn-radio="'Middle'" data-ng-click="setItems(10)">10</label>
<label class="btn btn-primary" ng-model="radioModel" btn-radio="'Right'" data-ng-click="setItems(15)">15</label>
</div>
//And don't forget in your table:
<tr data-ng-repeat="p in profiles | offset: (currentPage-1)*itemPerPage | limitTo: itemPerPage" >
在你的angularJs中:
var module = angular.module('myapp',['ui.bootstrap','dialogs']);
module.controller('myController',function($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);
};
});
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="‹"
next-text="›"
first-text="«"
last-text="»">
</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);
};
$scope.pageChanged();
关于分页的更多选项:Bootstrap UI pagination Directive
Angular UI引导-分页指令
查看UI Bootstrap的分页指令。我最终使用了它，而不是在这里发布的，因为它有足够的功能满足我目前的使用，并有一个完整的测试规范。
View
<!-- table here -->
<pagination
ng-model="currentPage"
total-items="todos.length"
max-size="maxSize"
boundary-links="true">
</pagination>
<!-- items/page select here if you like -->
控制器
todos.controller("TodoController", function($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);
});
});
