我正在使用ui-router,并且我有一个配置,其中我使用了一个具有控制器的父视图和一个具有自己控制器的子视图。每次我导航到其中一个子视图时,父控制器都会被再次实例化,从而执行不必要的服务器请求。我希望能够在子状态之间导航并重用由父控制器解析的变量。如何防止每次都实例化父控制器?这是我的路由配置:
$stateProvider
.state('researchLayoutEditor', {
url: '/research/:researchId/layoutEditor/:orderInGroup',
controller: 'layoutEditorController',
controllerAs: 'layoutEditorCtrl',
templateUrl: 'app/researchManagement/researchLayoutEditor/layoutEditor.html',
redirectTo: 'researchLayoutEditor.slide',
params: {
group: 'A',
orderInGroup: '0'
},
resolve: {
researchLayout: function (researchesService, $stateParams) {
return researchesService.getResearchLayout($stateParams.researchId, false);
},
research: function (researchesService, $stateParams) {
return researchesService.getResearch($stateParams.researchId);
}
}
}).state('researchLayoutEditor.slide', {
url: '/textual',
templateUrl: 'app/researchManagement/researchLayoutEditor/textSlide.html',
controller: 'textSlideController',
controllerAs: 'txtSlide'
}).state('researchLayoutEditor.movie', {
url: '/video',
templateUrl: 'app/researchManagement/researchLayoutEditor/movieSlide.html',
controller: 'movieSlideController',
controllerAs: 'movieSlide',
resolve: {
movieCategories: function (utilsService) {
return utilsService.getVideoCategories();
}
}
}).state('researchLayoutEditor.memory', {
url: '/memory',
templateUrl: 'app/researchManagement/researchLayoutEditor/memorySlide.html',
controller: 'memorySlideController',
controllerAs: 'memorySlide'
}).state('researchLayoutEditor.question', {
url: '/question',
templateUrl: 'app/researchManagement/researchLayoutEditor/questionSlide.html',
controller: 'questionSlideController',
controllerAs: 'questionSlide'
});
以下是HTML代码:
<div id="mainContent">
<!-- our nested state views will be injected here -->
<div ui-view class="inner-content"></div>
</div>
