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?

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

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();
}]);
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="‹"
data-next-text="›"
data-first-text="«"
data-last-text="»">
</ul>
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
下面的代码将有助于在后端提供自定义分页角repeat。
