Building AngularJS HTTP request in template

Question

I'm really new to AngularJS and got a WebApp-Template from my boss. I have to build an CRM and the template is FULL OF AngularJS. It's a really nice framework, but I have my problems with it.

I have this Controller to handle the articles:

(function () {
"use strict";
angular.module("app.tables", []).controller("articlesCtrl", ["$scope", "$http", "$filter",

    function ($scope, $http, $filter) {
        var init;
        $http.get('http://srv.ct-server.de/ctcrm/www/articles.php?method=fetchAll').success(function (data) {
            $scope.articles = data;
            console.log($scope.articles);
        }).
            error(function (data) {
                // log error
            })
            , $scope.searchKeywords = "", $scope.filteredArticles = [], $scope.row = "", $scope.select = function (page) {
            var end, start;
            return start = (page - 1) * $scope.numPerPage, end = start + $scope.numPerPage, $scope.currentPageArticles = $scope.filteredArticles.slice(start, end)
        }, $scope.onFilterChange = function () {
            return $scope.select(1), $scope.currentPage = 1, $scope.row = ""
        }, $scope.onNumPerPageChange = function () {
            return $scope.select(1), $scope.currentPage = 1
        }, $scope.onOrderChange = function () {
            return $scope.select(1), $scope.currentPage = 1
        }, $scope.search = function () {
            return $scope.filteredArticles = $filter("filter")($scope.articles, $scope.searchKeywords), $scope.onFilterChange()
        }, $scope.order = function (rowName) {
            return $scope.row !== rowName ? ($scope.row = rowName, $scope.filteredArticles = $filter("orderBy")($scope.articles, rowName), $scope.onOrderChange()) : void 0
        }, $scope.numPerPageOpt = [3, 5, 10, 20], $scope.numPerPage = $scope.numPerPageOpt[2], $scope.currentPage = 1, $scope.currentPageArticles = [], (init = function () {
            return $scope.search(), $scope.select($scope.currentPage)
        })()

    }
])}.call(this));

Without the Filters it works... But when I put in the last one

, $scope.numPerPageOpt = [3, 5, 10, 20], $scope.numPerPage = $scope.numPerPageOpt[2], $scope.currentPage = 1, $scope.currentPageArticles = [], (init = function () {
            return $scope.search(), $scope.select($scope.currentPage)
        })()

There comes the error

TypeError: Cannot read property 'slice' of undefined

The Array is still in the console. I dont understand this error.

This is my html:

    <section class="panel panel-default table-dynamic">
    <div class="panel-heading"><strong>Artikel</strong></div>

    <div class="table-filters">
        <div class="row">

Answer 1

You'll need to use the $http service provided by Angular and set your $scope variables with something like this:

$http({method: 'GET', url: '/db/articles.php' }).
    success(function(data, status, headers, config) {
        $scope.articles = data;
    }).
    error(function(data, status, headers, config) {
        // called asynchronously if an error occurs
        // or server returns response with an error status.
    });

Be sure to inject the $http service into your controllers like so:

angular.module("app.tables", []).controller("articlesCtrl", ["$scope", "$filter", "$http",
    function($scope, $filter, $http) {

Answer 2

In your template file, you can either use {{ articles }} or ng-repeat to loop over all articles. A controller is connected to a part in the template by ng-controller="MyController" .

It's all very basic and how angular works. I recommend watching a few tutorials... For instance, this one: http://www.ng-newsletter.com/posts/beginner2expert-scopes.html
