我有一个控制器,每个不同的路径传递不同的参数。我的routes.js文件看起来像这样 -
.when('/event/:eid/edit-question/:qid', {
templateUrl: 'views/edit-question.html',
controller: 'eventController',
controllerAs: 'eventCtrl',
resolve: {
"check": function (authService, $location) {
if (!authService.isLoggedIn()) {
$location.path('/login');
}
},
"params": function ($route) {
return $route.current.params;
}
}
})
.when('/event/edit-event/:eid', {
templateUrl: 'views/edit-event.html',
controller: 'eventController',
controllerAs: 'eventCtrl',
resolve: {
"check": function (authService, $location) {
if (!authService.isLoggedIn()) {
$location.path('/login');
}
},
"params": function ($route) {
return $route.current.params;
}
}
})
我在加载控制器之前解析了路径参数。 我的控制器功能看起来像这样 -
myApp.controller('eventController', ['$location','$rootScope', 'params', 'authService', 'apiService', function ($location,$rootScope, params,authService, apiService) {
let dash = this;
//all the route parameters will be resolved and stored here
dash.params = params;
//get the details of an event
dash.getTheEventDetail = () => {
apiService.getEventDetail(dash.params.eid).then(function successCallBack(response){
console.log(dash.params.eid);
dash.eventDetail = response.data.data;
});
}
dash.getTheEventDetail();
//get the detail of a question for the qid passed as parameter
dash.viewQuestion = () => {
console.log(dash.params.qid);
console.log(dash.eventDetail);
dash.questionDetail = dash.eventDetail.questions.filter(question => question._id === dash.params.qid);
console.log(dash.questionDetail);
}
当我尝试访问路由/事件/:eid / edit-question /:qid时,viewQuestion函数在getTheEventDetail之前执行,因为dash.eventDetail仍未定义 viewQuestion在编辑问题视图中的控制器初始化时被调用,如下所示。
<div ng-init="eventCtrl.viewQuestion()"></div>
可以在getTheEventDetail()的末尾调用viewQuestion函数。但是这会导致每次调用getTheEventDetail时调用viewQuestion。在这种情况下,有一种很好的方法来处理routeParams。
