Javascript 如何访问和更新ui路由器子状态的onEnter方法中的父状态解析数据
我的ui路由器状态如下: 父状态Javascript 如何访问和更新ui路由器子状态的onEnter方法中的父状态解析数据,javascript,angularjs,Javascript,Angularjs,我的ui路由器状态如下: 父状态 $stateProvider .state('profile',{ url: '/profile', views: { 'contentFullRow': { templateUrl: 'ng/templates/profile/partials/profile-heading-one.html',
$stateProvider
.state('profile',{
url: '/profile',
views: {
'contentFullRow': {
templateUrl: 'ng/templates/profile/partials/profile-heading-one.html',
controller: function($scope, profile,misc){
$scope.profile = profile;
$scope.misc = misc;
}
},
'contentLeft': {
templateUrl: 'ng/templates/profile/partials/profile-body-one.html',
controller: function($scope, profile,misc){
$scope.profile = profile;
$scope.misc = misc;
}
},
'sidebarRight': {
templateUrl: 'ng/templates/profile/partials/todo-list-one.html',
controller: function($scope, profile,misc){
$scope.profile = profile;
$scope.misc = misc;
}
}
},
resolve: {
profile: function($http){
return $http({method: 'GET', url: '/profile'})
.then (function (response) {
console.log(response.data)
return response.data;
});
},
misc: function($http){
return $http({method: 'GET', url: '/json/misc'})
.then (function (response) {
console.log(response.data)
return response.data;
});
}
}
})
子状态
.state('profile.social', {
url: '/social',
controller:function($scope, profile, misc){
$scope.profile = profile;
$scope.misc = misc;
},
template: '<div ui-view></div>'
})
.state('profile.social.create',{
url: '/create',
onEnter: function($state){
//Will call a modal here...
//How do I access or update `$scope.profile`
//so far am doing this and it works
$state.$current.locals.globals.profile.first_name = 'My New name';
//Is there any better way of doing this?
}
})
这是可行的,但我想知道是否有更好的方法可以做到这一点?正确的做法是不要尝试从控制器外部访问控制器
$scope
。相反,您应该将配置文件数据移动到服务,并将其注入控制器和oneter函数(根据需要)。通过将配置文件数据分离到服务中,您现在也可以从其他任何地方访问它:)
例如:
.service('ProfileService', function(){
var state = {};
this.loadProfile = function(){
return $http({method: 'GET', url: '/profile'})
.then (function (response) {
console.log(response.data);
state.profile = response.data;
return state.profile;
});
};
this.getState = function(){
return state;
};
});
// the controller
controller: function($scope, ProfileService){
$scope.state = ProfileService.getState();
}
// on enter
onEnter: function($state, ProfileService){
var state = ProfileService.getState();
state.profile.first_name = 'New Name';
}
我将配置文件数据包装在一个容器中(state
),以便可以更改配置文件键本身。因此,在视图中,您需要像这样引用您的配置文件:state.profile.first\u name
在resolve内部,您还需要注入服务,并运行load函数返回相关的承诺(以便resolve实际工作)
在不了解您的需求的情况下,很难描述实现这一点的最佳方法,但总而言之,您应该将您的配置文件数据拉入其自己的服务中,并在需要时注入它。服务还应封装在服务数据加载后解决的任何承诺。谢谢。关于我的需求,我目前在控制器中有一个模式框,例如:.
state('profile.social.create',{url:'/create',controller:function($modal){\\modal code});
唯一的问题是,当点击链接时,模板需要一些时间才能加载,所以我决定将模式代码移动到onEnter
method。如果有帮助的话,您也可以将模板预加载到模板缓存中(在初始加载时)。是的。谢谢您的回答和评论。模板缓存使模板加载速度更快
.service('ProfileService', function(){
var state = {};
this.loadProfile = function(){
return $http({method: 'GET', url: '/profile'})
.then (function (response) {
console.log(response.data);
state.profile = response.data;
return state.profile;
});
};
this.getState = function(){
return state;
};
});
// the controller
controller: function($scope, ProfileService){
$scope.state = ProfileService.getState();
}
// on enter
onEnter: function($state, ProfileService){
var state = ProfileService.getState();
state.profile.first_name = 'New Name';
}
