我试图通过 Google Charts Angular 指令模块让 Angular 与 Google Charts 一起工作，但似乎无法让它工作。我收到此错误:

Uncaught Error: [$injector:modulerr] Failed to instantiate module myApp due to: Error: [$injector:nomod] Module 'myApp' is not available! You either misspelled the module name or forgot to load it. If registering a module ensure that you specify the dependencies as the second argument.

Angular 代码:

var myApp = angular.module("myApp", ['googlechart']);

myApp.factory("DataService", ["$http", function ($http){
    var getData = function(callback){
        var url = 'api-url-returns-json';
        $http.get(url).success( function(response) {
            callback(response);
        });
    }
    return {
            getDashboardData: getData
        }
}]);

myApp.controller("dashboardController", ["$scope", "DataService", "ClockProvider", function ($scope, DataService, ClockProvider){
    DataService.getDashboardData(function(data){
        $scope.dashboard = data;
    });
    var intervals = ["0", "30"];
    ClockProvider.run(intervals, function(){
        DataService.getDashboardData(function(data){
            $scope.dashboard = data;
        });
    });
}]);


angular.module("myApp", ["googlechart", "googlechart-docs"]).controller("GenericChartCtrl", function ($scope) {
    $scope.chartObject = {};

    $scope.chartObject.type = "BarChart";

    $scope.onions = [
        {v: "Onions"},
        {v: 3},
    ];

    $scope.chartObject.data = {"cols": [
        {id: "t", label: "Topping", type: "string"},
        {id: "s", label: "Slices", type: "number"}
    ], "rows": [
        {c: [
            {v: "Mushrooms"},
            {v: 3},
        ]},
        {c: $scope.onions}
        {c: [
            {v: "Olives"},
            {v: 31}
        ]},
        {c: [
            {v: "Zucchini"},
            {v: 1},
        ]},
        {c: [
            {v: "Pepperoni"},
            {v: 2},
        ]}
    ]};

    $scope.chartObject.options = {
        'title': 'How Much Pizza I Ate Last Night'
    };
});

HTML:

    <html ng-app="myApp">
        <head>
            <script src="ng-google-chart.js"></script>
            <script src="app.js"></script>
        </head>
        <body>
            <div class="side front" ng-controller="GenericChartCtrl">
                <div google-chart chart="chartObject"">
                </div>
            </div>
        </body>
   </html>

最佳答案

首先，您在声明和调用 AngularJS 模块之间弄错了。

要声明一个模块，您可以使用:

var myApp = angular.module("<Your app name>", [<Your dependencies>]);

然而，调用模块(例如创建一个controller)只需使用:

//Notice that you don't put the [] in .module()
angular.module("myApp").controller

修复后，如果问题依旧，请查看引用资料。请记住以正确的顺序加载所有必需的 JS 代码(在加载应用程序之前加载依赖项)。例如:

<script src="Your dependencies path"></script>
<script src="Your Angular app path"></script>
