即使模型得到更新,視圖也不會更新。我搜索了這個問題,我得到了一些解決方案,即使用setTimeout
或$timeout
函數。 我試過上面的函數,但即使使用$超時函數模型得到更新和查看不是。
我是從一個服務設置模型的價值。當一個控制器在服務中設置值時,另一個控制器監聽該服務並更新其模型。
注工廠服務
function loadNoteFactory($http) {
var baseURL = "SOME_URL";
var sessionId = "sessionId";
return {
getNotes: function() {
return $http.get(baseURL+"notes?"+sessionId);
},
addNote: function(note) {
return $http.post(baseURL+"note?"+sessionId, note);
},
editNote: function(tag, tagname) {
return $http.put(baseURL +"note/"+ note.id+"?"+sessionId, note);
},
deleteTag: function(tagId) {
return $http.delete(baseURL +"note/"+ note.id+"?"+sessionId);
}
};
}
廠服務
function loadSelectedNoteFactory($rootScope){
var selectedNoteFactory = {};
selectedNoteFactory.note = {};
selectedNoteFactory.setCurrentNote = function(note) {
this.note = note;
$rootScope.$broadcast('noteChanged');
};
return selectedNoteFactory;
}
位指示1 - 服務設置新的價值
function loadNoteListControllar($scope, NoteFactory, tagBasedNoteSearchService, selectedNoteFactory){
getUsersNotes();
function getUsersNotes(){
NoteFactory.getNotes().success(function(data) {
$scope.notes = data.notes;
selectedNoteFactory.setCurrentNote($scope.notes[0]);
});
}
$scope.onSelectNote = function(note){
selectedNoteFactory.setCurrentNote(note);
}
}
控制器2 - 自我更新的變化,服務
function loadDetailControllar($scope, $timeout, selectedNoteFactory){
$scope.note = {};
$scope.$on('noteChanged', testme);
function testme(){
$timeout(function(){
$scope.note = selectedNoteFactory.note;
}, 500);
}
}
的Html
<div class="tagWidget" ng-app="tagWidget">
<div class="notelistcontainer floatleft" ng-controller="NoteListController" style="width: 20%; height: 100%;">
<div class="notelist" style="border: solid 5px grey;">

注漿Cotroller,服務和指令
angular.module('tagWidget', [])
.factory('tagBasedNoteSearchService', loadTagBasedNoteSearchService)
.factory('NoteFactory', loadNoteFactory)
.factory('SelectedNoteFactory', loadSelectedNoteFactory)
.directive('editableDiv', loadEditableDiv)
.directive('toggleIcon', loadToggleIcon)
.controller('NoteListController', ['$scope', 'NoteFactory', 'tagBasedNoteSearchService', 'SelectedNoteFactory', loadNoteListControllar])
.controller('DetailController', ['$scope', '$timeout', 'SelectedNoteFactory', loadDetailControllar])
'tagBasedNoteSearchService', 'SelectedNoteFactory', loadTagControllar]);
我們可以看到NoteFactory.getNotes()的代碼嗎?我認爲超出範圍的變量設置的問題可能在那裏。 – bri
@bri添加了NoteFactory服務代碼。 –
你的代碼在哪裏調用,或者說更好的說_injecting_'loadDetailControllar','loadNoteListControllar','loadNoteFactory'等等? –
