Angularjs延迟加载时请求转换的多个指令

我正在尝试使用ui.router、ocLazyLoad、Foundation和angular Foundation来设置一个简单的angularjs应用程序。

该应用程序是一个多视图应用程序，其组件使用ocLazyLoad进行延迟加载。我设置视图和关联的控制器没有问题。但是，我在尝试显示Foundation警报时遇到问题。当我尝试查看我的警报（路线1）时，我会收到空警报。下面的堆栈跟踪。

为什么angular应用警报指令两次？这里有一个plunker：http://goo.gl/lhtD0c

Error: [$compile:multidir] Multiple directives [alert, alert] asking for transclusion on:

我的索引正文如下：

<body>
    <div>
        <a class="button" ui-sref="route1">Route 1</a>
        <a class="button" ui-sref="route2">Route 2</a>
    </div>
    <div ui-view></div>
</body>

与此页面关联的javascript是：

var myapp = angular.module('myapp', ['ui.router', 'oc.lazyLoad', 'mm.foundation'])
myapp.config(function($stateProvider, $urlRouterProvider){
  // For any unmatched url, send to /route2
  $urlRouterProvider.otherwise('/route2')
  $stateProvider
    .state('route1', {
        url: "/route1",
        controller: 'Route1',
        templateUrl: "route1.html",
        resolve: {
            loadCtrl: ['$ocLazyLoad', function($ocLazyLoad) {
                return $ocLazyLoad.load({
                    name: 'myapp',
                    files: ['route1.js']
                })
            }]
        }
    })
    .state('route2', {
        url: "/route2",
        templateUrl: "route2.html"
    })
});
$(function() {
    Foundation.global.namespace = '';
    $(document).foundation();
})

这些问题与路线1有关。这是route1模板。

<div ng-controller="Route1">
    Route 1 - {{ message }}
    <br/>
    <alert ng-repeat="alert in alerts"
           type="alert.type"
           close="closeAlert($index)">{{alert.msg}}</alert>
</div>

最后是route.js-

angular.module('myapp').controller('Route1', ['$scope', function($scope) {
    $scope.message = 'Hello, world!'
    $scope.alerts = [
        { type: 'danger', msg: 'Oh snap! Change a few things up and try submitting again.' },
        { type: 'success round', msg: 'Well done! You successfully read this important alert message.' }
    ];
}]);

问题是它正在重新加载您的"myapp"模块依赖项。只需配置ocLazyLoad，就不会像这样重新加载基础：

$ocLazyLoadProvider.config({
    loadedModules: ['mm.foundation']
});

它将是这样的：

var myapp = angular.module('myapp', ['ui.router', 'oc.lazyLoad', 'mm.foundation'])
myapp.config(function($stateProvider, $urlRouterProvider, $ocLazyLoadProvider){
  // For any unmatched url, send to /route2
  $urlRouterProvider.otherwise('/route2')
  $ocLazyLoadProvider.config({
        loadedModules: ['mm.foundation']
    });
  $stateProvider
    .state('route1', {
        url: "/route1",
        controller: 'Route1',
        templateUrl: "route1.html",
        resolve: {
            loadCtrl: ['$ocLazyLoad', function($ocLazyLoad) {
                return $ocLazyLoad.load({
                    name: 'myapp',
                    files: ['route1.js']
                })
            }]
        }
    })
    .state('route2', {
        url: "/route2",
        templateUrl: "route2.html"
    })
});
$(function() {
    Foundation.global.namespace = '';
    $(document).foundation();
})

替换此代码

<alert ng-repeat="alert in alerts"
           type="alert.type"
           close="closeAlert($index)">{{alert.msg}}</alert>

通过

<div ng-repeat="alert in alerts">
  <alert type="alert.type" close="closeAlert($index)">{{alert.msg}}</alert>
</div>

我终于做到了。问题是ocLazyLoad正在重新加载"myapp"模块。这导致依赖项重新加载。其中一个依赖项是mm.foundation，它重新处理所有指令，为每对创建一个克隆。

为了防止这种情况发生，我没有将第二个控制器绑定到myapp。相反，我创建了一个新的应用程序"route1app"。你可以在这里看到更新的plunker：http://goo.gl/lhtD0c
