Question

我有两个模板，分别有各自的控制器和服务文件。一个模板（fleetListTemplate）控制器（fleetListController）从其服务文件（fleetService）加载数据并在其视图中显示（fleetListTemplate）。

当发生这种情况时，我点击来自fleetService的其中一个加载数据，我应该将fleetListController链接到fleetSummaryController以从其服务文件（fleetSummaryService）获取数据并显示在fleetSummaryTemplate视图中。

有人可以帮我编码吗？谢谢。

以下是各自的模块，模板，控制器和服务文件。

fleetListModule

"use strict";

angular.module("fleetListModule", []);

fleetListTemplate

<div class="panel1 panel-primary">
    <div class="panel-heading" align="center">TRUCKS</div>
    <table class="table table-bordered table-condensed table-striped">

        <tr>
            <th>TruckID</th>
            <th>Status</th>
            <th>Dest.</th>
            <th>Alerts</th>
        </tr>
        <tr ng-repeat="truck in trucks" ng-click="summaryData()">
            <td>{{truck.truckID}}</td>
            <td>{{truck.status}}</td>
            <td>{{truck.destination}}</td>
            <td>{{truck.alerts}}</td>
        </tr>

这个简单的示例向您展示如何在“一个应用程序”中的两个控制器之间共享数据使用普通服务。

angular.module("app", []);

        ///controller1
        angular.module("app").controller("controller1", function ($scope, service) {
            $scope.lists = [
                { name: "maher" },
                { name: "Gaurav Ram" },
                { name: "Shaun Scovil" }
            ];

            $scope.send = function () {
                service.set("lists", $scope.lists); //set(key, value)
                $scope.lists = []; //optional
            }

        });

        ///controller2
        angular.module("app").controller("controller2", function ($scope, service) {
            $scope.lists = [];

            //get data from broadcast on the root
            service.get("lists"); // get(key)

            //set data
            $scope.resive = function () {
                if (angular.isUndefined($scope.broadcast)) {
                    $scope.alert = "No data to resive!";
                } else {
                    $scope.alert = null;
                    $scope.lists = $scope.broadcast;
                }
            }
        });

        ///service
        angular.module("app").service("service", function ($rootScope) {
            this.set = function (key, value) {
                $rootScope.$broadcast(key, value);
            }

            this.get = function (key) {
                $rootScope.$on(key, function (event, data) {
                    $rootScope.broadcast = data;
                });
            }
        });
