在模板中构建AngularJS HTTP请求

Question

我真的是AngularJS的新手，并且从老板那里得到了一个WebApp-Template。 我必须建立一个CRM，模板是FULL OF AngularJS。 这是一个非常好的框架，但我对此有疑问。

我有这个控制器来处理文章：

(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));

如果没有过滤器，它将起作用...但是当我放入最后一个过滤器时

, $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)
        })()

出现错误

TypeError：无法读取未定义的属性“切片”

阵列仍在控制台中。 我不明白这个错误。

这是我的html：

    <div class="panel-heading"><strong>Artikel</strong></div>

请帮我

Answer 1

您需要使用Angular提供的$http服务，并使用以下方式设置$scope变量：

$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.
    });

确保将$http服务注入到您的控制器中，如下所示：

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

Answer 2

在模板文件中，您可以使用{{ articles }}或ng-repeat遍历所有文章。 控制器通过ng-controller="MyController"连接到模板中的零件。

这都是非常基本的，并且角度是如何工作的。 我建议观看一些教程...例如，这个教程： http : //www.ng-newsletter.com/posts/beginner2expert-scopes.html
