我想通过解决方案将数据(contactName
)从状态传递给控制器:
.state({
name: 'contact.detail.overlay',
abstract: true,
component: 'overlayContent',
resolve: {
contactName: (originalContact, $rootScope, ContactService) => {
$rootScope.contactName = ContactService.getContactName(originalContact)
return $rootScope.contactName
}
}
})
在我的状态上一切正确,contactName
也是正确的,但我的overlayContent
控制器无法访问它,您是否有解决方案在控制器中拥有$rootScope.contactName
访问权限?
编辑: 控制器:
class overlayContentComponent {
constructor($state, $interpolate, $scope) {
'ngInject'
this.$scope = $scope
this.$state = $state
this.$interpolate = $interpolate
}
/**
*
* On initialization hook, let's check if an overlay title
* has been defined for the current state.
*/
$onInit() {
const stateData = this.$state.current.data || { title: '' }
this.overlayTitle = angular.isDefined(stateData.title) ? this.$interpolate(stateData.title)() : ''
}
}
export const overlayContentComponent = {
template: require('./overlay-content.html'),
controller: overlayContentComponent
}
我可以通过contactName
访问我的控制器中的this.$scope.$root.contactName
,但我希望通过其他替代方式避免$scope.$root
答案 0 :(得分:0)
更改构造函数:
constructor($state, $interpolate, $scope, contactName) {
'ngInject';
// The variable you want:
this.contactName = contactName;
this.$scope = $scope
this.$state = $state
this.$interpolate = $interpolate
}
现在应该将'contactName'解析注入该状态的控制器(解析所在的位置)。这应该允许您在控制器中访问它,如上所述。
