Troubleshooting problem in AngularJS: $http request causing DOM to not update when calling jQuery function

I'm encountering an issue where the DOM is not updating when I make a $http request in a jQuery function call.

Please take a look at the Plunker

In my code script.js, for testing purposes, I have $scope.components defined both globally and within a function. However, everything works fine when I hardcode the JSON value into the global variable. The problem arises when I fetch the JSON as a $http response; the expand and collapse functionality of the tree structure stops working.

Below is the section of code handling the $http request:

$scope.init = function init() {
$http.get('treeData.json').success(function(data) {
  $scope.components = data;
}).error(function(data) {

});

};

Please help me identify what might be going wrong here.

Answer №1

The reason behind this issue is that your jQuery code is being executed before fetching the data from treedata.json. Utilizing `$http` will generate a promise, so it is crucial to move your jQuery logic after the promise has been resolved. You can check out the updated plunker below for reference:

Answer №2

Begin by setting up your components, as shown in the example below: $scope.components = [];

Answer №3

Seems like the response data from the server is not formatted as JSON. By default, $http.get expects a JSON return type. Because of this, your success function is not being triggered.

Solution You can refer to the Angular documentation for proper usage of $http. The recommended approach is to use get like this:

$http.get('/someUrl', config).then(successCallback, errorCallback);

Answer №4

test $rootScope.$digest( $rootScope.elements = info );
