AngularJS 1.2.0：延遲加載控制器和模板

Question

我是AngularJS的新手。 我正在使用以下代碼來實現延遲加載依賴性。

https://github.com/matys84pl/angularjs-requirejs-lazy-controllers/

1.0.7可以很好地工作，但是延遲承諾無法在1.2.0版本中加載模板。

在js/lib/utils/route-config.js

routeDefinition.template = function () {
            /*
             *  Here is the problem, 'html' is undefined on page load. 
             *  But if we click the menu navigation, the 'html' is getting loaded. 
             *  I am not sure how to achieve promise for loading template in RequireJS.
             */
            return html;
        };
        routeDefinition.controller = controllerName;


routeDefinition.resolve = {
        delay:function ($q, $rootScope) {
            defer = $q.defer();
            if (!html) {
                var dependencies = [controllerName, "text!" + templateUrl];
                if (directives) {
                    dependencies = dependencies.concat(directives);
                }
                require(dependencies, function () {
                    var controller = arguments[0],
                        template = arguments[1];

                    for (var i = 2; i < arguments.length; i++) {
                        lazyDirectives.register(arguments[i]);
                    }

                    $controllerProvider.register(controllerName, controller);
                    html = template;
                    defer.resolve();
                    $rootScope.$apply()
                })

            } else {
                defer.resolve();
            }
            return defer.promise;
        }

我用下面的代碼更改了代碼，即不使用template ，而是將其更改為templateUrl ，並且效果很好。 由於我是在salesforce.com中實現的，而visualforce頁面不支持html擴展，所以我不想使用templateUrl 。

routeDefinition.templateUrl = 'js/'+templateUrl;
        routeDefinition.controller = controllerName;
        routeDefinition.resolve = {
            delay:function ($q, $rootScope, $http) {
                defer = $q.defer();
                if (!html) {
                    //var dependencies = ["lib/text!" + templateUrl, controllerName];
                    var dependencies = [controllerName];
                    if (routeDependends) {
                        dependencies = dependencies.concat(routeDependends.directives);
                        dependencies = dependencies.concat(routeDependends.services);
                        dependencies = dependencies.concat(routeDependends.filters);
                    }

                    require(dependencies, function () {
                        var controller = arguments[0], 
                        //template = arguments[0],
                        incCnt = 1, 
                        directiveCnt = (routeDependends.directives.length+incCnt),
                        serviceCnt = (routeDependends.directives.length+routeDependends.services.length+incCnt),
                        filterCnt = (routeDependends.directives.length+routeDependends.services.length+routeDependends.filters.length+incCnt);

                        $controllerProvider.register(controllerName, controller);

                        if(routeDependends.directives.length > 0)
                            for (var i = incCnt; i < directiveCnt; i++) { onDemandDependencies.registerDirectives(arguments[i]); }
                        if(routeDependends.services.length > 0)
                            for (var i = directiveCnt; i < serviceCnt; i++) { onDemandDependencies.registerServices(arguments[i]); }
                        if(routeDependends.filters.length > 0)
                            for (var i = serviceCnt; i < filterCnt; i++) { onDemandDependencies.registerFilters(arguments[i]); }

                        //html = template;
                        defer.resolve();
                        $rootScope.$apply()
                    });
                } else {
                    defer.resolve();
                }
                return defer.promise;
            }
        }
        console.log(routeDefinition);
        return routeDefinition;

任何幫助表示贊賞。 提前致謝。

目前尚不清楚您的html的加載方式，但是如果問題與“ visualforce頁面不支持html擴展名”有關，則可以在現有html文件中使用<script>標記實現模板，如下所示：

<script id="views/view1.html" type="text/ng-template">
    <h1>View1</h1>
    <div>View Message: {{message}}</div>
    <a href="#/home">Home</a>
</script>

ng-template角度文檔：
http://docs.angularjs.org/api/ng.directive:script

這是一個模板在index.html編碼的插件：
