Working on an AngularJS project and I've ran into the following problem:
When using locally stored / hard coded data, the pagination works fine. When using remotely stored data, the pagination does not work properly.
I have searched quite a bit, but couldn't find the solution to my problem, so here are the code snippits:
The HTML:
<div ng-controller="ngTableCtrl">
<p><strong>Pagina:</strong> {{tableParams.page()}}</p>
<p><strong>Aantal weergegeven:</strong> {{tableParams.count()}}</p>
<table ng-table="tableParams" class="table table-striped" template-pagination="custom/pager">
<tr ng-repeat="x in names">
<td data-title="'Name'">{{x.Name}}</td>
<td data-title="'City'">{{x.City}}</td>
<td data-title="'Country'">{{x.Country}}</td>
</tr>
</table>
<script type="text/ng-template" id="custom/pager">
<ul class="pager ng-cloak">
<li ng-repeat="page in pages"
ng-class="{'disabled': !page.active, 'previous': page.type == 'prev', 'next': page.type == 'next'}"
ng-show="page.type == 'prev' || page.type == 'next'" ng-switch="page.type">
<a ng-switch-when="prev" ng-click="params.page(page.number)" href="">« Previous</a>
<a ng-switch-when="next" ng-click="params.page(page.number)" href="">Next »</a>
</li>
<li>
<div class="btn-group">
<button type="button" ng-class="{'active':params.count() == 2}" ng-click="params.count(2)" class="btn btn-default">2</button>
<button type="button" ng-class="{'active':params.count() == 5}" ng-click="params.count(5)" class="btn btn-default">5</button>
<button type="button" ng-class="{'active':params.count() == 10}" ng-click="params.count(10)" class="btn btn-default">10</button>
<button type="button" ng-class="{'active':params.count() == 15}" ng-click="params.count(15)" class="btn btn-default">15</button>
</div>
</li>
</ul>
</script>
</div>
The JS:
app.controller('ngTableCtrl2', function ($scope, $http, $filter, ngTableParams) {
$http.get('http://www.w3schools.com/angular/customers.php')
.success(function (response) {$scope.names = response.records;});
$scope.tableParams = new ngTableParams({
page: 1, // show first page
count: 5, // count per page
sorting: {
name: 'asc' // initial sorting
}
}, {
total: data.length, // length of data
getData: function ($defer, params) {
// use build-in angular filter
var orderedData = params.sorting() ? $filter('orderBy')(data, params.orderBy()) : data;
$defer.resolve(orderedData.slice((params.page() - 1) * params.count(), params.page() * params.count()));
}
});
});
The webpage ( live version: http://178.62.232.175:8080/STANDARD/#/app/table/data ) shows all results in the first table (remote, from $http.get), whilst the second table, shows only the set results?! (2, 5, 10, 15) The code is identical, except for:
<tr ng-repeat="x in names">
used to display remote data and is replaced by:
<tr ng-repeat="x in $data">
to display raw data as such:
var data = [{
Name: "Alfreds Futterkiste", City: "Berlin", Country: "Germany"},{
Name: "Ana Trujillo Emparedados", City: "México D.F.", Country: "Mexico"},{
Name: "Antonio Moreno Taquería", City: "México D.F.", Country: "Mexico"},{
Name: "Around the Horn", City: "London", Country: "UK"},{
Name: "B's Beverages", City: "London", Country: "UK"},{
Name: "Berglunds snabbköp", City: "Luleå", Country: "Sweden"},{
Name: "Blauer See Delikatessen", City: "Mannheim", Country: "Germany"},{
Name: "Blondel père et fils", City: "Strasbourg", Country: "France"},{
Name: "Bólido Comidas preparadas", City: "Madrid", Country: "Spain"},{
Name: "Bon app", City: "Marseille", Country: "France"},{
Name: "Bottom-Dollar Marketse", City: "Tsawassen", Country: "Canada"},{
Name: "Cactus Comidas para llevar", City: "Buenos Aires", Country: "Argentina"}
];
The pagination of the second table works as it should. What must I edit to make it work with remote data?
First of all your code is using the local data array as a source in ngTables getData callback and it is not clear what you are presenting as a comparison since you did not actually try AJAX Data Loading from the official examples .
Instead I would expect it to have an api call to the server using $http.get.
Remember for server side paging to work you must update the total count each time you query for data because they may have changed. Also you will have to consider a server side solution for sorting as well.
Here is a working sample using the github api as a test service.
var app = angular.module('main', ['ngTable']);
app.controller('MainCtrl', function($scope, $http, ngTableParams) {
$scope.tableParams = new ngTableParams({
page: 1,
count: 5,
}, {
getData: function ($defer, params) {
var page = params.page();
var size = params.count();
var testUrl = 'https://api.github.com/search/repositories';
var search = {
q: 'angular',
page: page,
per_page: size
}
$http.get(testUrl, { params: search, headers: { 'Content-Type': 'application/json'} })
.then(function(res) {
params.total(res.data.total_count);
$defer.resolve(res.data.items);
}, function(reason) {
$defer.reject();
}
);
},
});
