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();
}]);

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) * $scope.itemPerPage;
};
});
//and our filter
module.filter('offset', function() {
return function(input, start) {
start = parseInt(start, 10);
return input.slice(start);
};
});
我更新了斯科特的情况。NET的plunkr http://plnkr.co/edit/FUeWwDu0XzO51lyLAEIA?p=preview,这样它就可以使用angular、angular-ui和bootstrap的新版本。
控制器
var todos = angular.module('todos', ['ui.bootstrap']);
todos.controller('TodoController', function($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>
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="#">«</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="#">»</a></li>
</ul >
它很有用
我刚刚做了一个JSFiddle,显示分页+搜索+排序每列使用btford代码:http://jsfiddle.net/SAWsA/11/
这是一个纯javascript解决方案,我把它包装成一个Angular服务来实现像谷歌搜索结果那样的分页逻辑。
在http://codepen.io/cornflourblue/pen/KVeaQL/上的CodePen工作演示
细节和解释在这篇博文中
function PagerService() {
// service definition
var service = {};
service.GetPager = GetPager;
return service;
// service implementation
function GetPager(totalItems, currentPage, pageSize) {
// default to first page
currentPage = currentPage || 1;
// default page size is 10
pageSize = pageSize || 10;
// calculate total pages
var totalPages = Math.ceil(totalItems / pageSize);
var startPage, endPage;
if (totalPages <= 10) {
// less than 10 total pages so show all
startPage = 1;
endPage = totalPages;
} else {
// more than 10 total pages so calculate start and end pages
if (currentPage <= 6) {
startPage = 1;
endPage = 10;
} else if (currentPage + 4 >= totalPages) {
startPage = totalPages - 9;
endPage = totalPages;
} else {
startPage = currentPage - 5;
endPage = currentPage + 4;
}
}
// calculate start and end item indexes
var startIndex = (currentPage - 1) * pageSize;
var endIndex = startIndex + pageSize;
// create an array of pages to ng-repeat in the pager control
var pages = _.range(startPage, endPage + 1);
// return object with all pager properties required by the view
return {
totalItems: totalItems,
currentPage: currentPage,
pageSize: pageSize,
totalPages: totalPages,
startPage: startPage,
endPage: endPage,
startIndex: startIndex,
endIndex: endIndex,
pages: pages
};
}
}
