ng-repeat list in AngularJS isnt updated when an ajax call changing its value

2024/2/27 8:49:25

I'm totally confused. Why doesn't my ng-repeat refresh when there's an ajax call changing its value? I've seen many Q&As here, but none of them talked about ajax call.


<div class="row" ng-controller="EntryCtrl"><div id="treeview" class="col-xs-4 col-sm-4 col-md-4 col-lg-4"><ul><li ng-repeat="root in rootEntry">{{root.Name}}</li></ul></div>


function EntryCtrl ($scope, $http) {$scope.rootEntry = [];$http.get('read/root').success(function(root) {$scope.rootEntry = root;console.log($scope.rootEntry);});

And the console did log an array the server returned. But the list in html never got updated. If I used $scope.$apply, an error concerning $digest would happen.

Console Output

[Object]0: ObjectAttributes: nullId: "534580464aac494e24000001"Name: "Registry"Path: ""__proto__: Objectlength: 1__proto__: Array[0]

So it's the structure of root the server returns. Would it be the problem of data type? Because it's Object rather than Array. I use Golang as server and use json.Marshal() to pack the data from MongoDB.


function EntryCtrl ($scope, $http) {$scope.rootEntry = [];$http.get('read/root').success(function(root) {$scope.rootEntry = root;console.log($scope.rootEntry);});console.log($scope.rootEntry);

The latter output is []. It's likely because of async of $http, so will it the reason?


I know why. I used a plugin called jsTree, which will do some decorations with the node, so the node I inserted would be overwritten.

Thank you all.


I've tested your code and as tymeJV said ,there is no problem with your implementation, i would suggest checking the console window for some possible errors.


function EntryCtrl ($scope, $http) {$scope.rootEntry = [];$http.get('').success(function(root) {$scope.rootEntry = root;console.log($scope.rootEntry);});
