Populate jQuery UI accordion after AngularJS service call

All we need is an easy explanation of the problem, so here it is.

I’m currently trying to build an AngularJS app where I’m using a jQuery UI accordion control.

The problem is, that the jQuery UI accordion is initiated before my AngularJS service is done loading data from the server. In other words: the accordion doesn’t have any data when it’s initiated and thus does not show when the data from AngularJS is populated.

The view looks like this:

<!-- Pretty standard accordion markup omitted -->

My AngularJS controller looks like this:

app.controller('orderController', function ($scope, orderService, userService) {
// Constructor for this controller

function init() {
    $scope.selected = {};
    $scope.totalSum = 0.00;
    $scope.shippingDate = "";
    $scope.selectedShippingAddress = "";
    $scope.orderComment = "";
    $scope.agreements = false;
    $scope.passwordResetSuccess = false;
    $scope.passwordResetError = true;

    userService.getCurrentUser(2).then(function (response) {
        $scope.user = response.data;

        orderService.getProductCategoriesWithProducts($scope.user).then(function (d) {
            $scope.categories = d.data;

// Other methods omitted

And my AngularJS services looks like this:

app.service('orderService', function ($http) {
    this.getProductCategoriesWithProducts = function (user) {
        return $http.post('url to my service', user);

app.service('userService', function ($http) {
    this.getCurrentUser = function(companyId) {
        return $http.get('url to my service' + companyId + '.aspx');

    this.resetPassword = function() {
        return true;

Is there any way to tell the accordion to “wait” to initialise until the data is returned from the service? 🙂

Thanks in advance!


I tried chaining the methods and added some logging and it seems that the accordion is in fact initiated after the JSON is returned from the service.

    userService.getCurrentUser(2).then(function(response) {
        $scope.user = response.data;
    }).then(function() {
        orderService.getProductCategoriesWithProducts($scope.user).then(function(d) {
            $scope.categories = d.data;
            console.log("categories loaded");
        }).then(function () {
            console.log("accordion loaded");

However, it doesn’t display the accordion 🙁 The first accordion div looks fine in the generated DOM:

<div id="b2b-line-accordion" class="ui-accordion ui-widget ui-helper-reset" role="tablist"> 

But the rest of the markup (which is databound with angular) itsn’t initiated.

Complete markup:

<div id="b2b-line-accordion">
    <div ng-repeat="productCategory in categories">
        <h3>{{ productCategory.CategoryName }}</h3>
        <div class="b2b-line-wrapper">
                      <th>HF varenr.</th>
                <tr ng-repeat="product in productCategory.Products">
                    <td>{{ product.ItemGroupName }}</td>
                    <td>{{ product.ItemAttribute }}</td>
                        <select ng-model="product.SelectedVariant"
                                ng-options="variant as variant.VariantUnit for variant in product.Variants"
                                ng-init="product.SelectedVariant = product.Variants[0]"
                                ng-change="calculateLinePrice(product); calculateTotalPrice();">
                    <td>{{ product.ItemNumber }}</td>
                    <td class="line-amount">
                        <span class="ensure-number-label" ng-show="product.IsNumOfSelectedItemsValid">Indtast venligst et tal</span>
                        <input type="number" class="line-amount" name="amount" min="0" ng-change="ensureNumber(product); calculateLinePrice(product); calculateTotalPrice();" ng-model="product.NumOfSelectedItems" value="{{ product.NumOfSelectedItems }}" />
                       <input type="text" name="line-comments" ng-model="product.UserComment" value="{{ product.UserComment }}" /></td>
                    <td><span class="line-sum">{{ product.LinePrice | currency:"" }}</span></td>


Finally I found a way around this! I’m not entirely sure if it’s that pretty and if it’s the Angular-way of doing stuff (I guess it isn’t)

Made a directive with the following code:

app.directive('accordion', function () {
    return {
         restrict: 'A',
         link: function ($scope, $element, attrs) {
             $(document).ready(function () {
                $scope.$watch('categories', function () {
                    if ($scope.categories != null) {

So basically when the DOM is ready and when the categories array changes (which it does when the data has been loaded), I’m initiating the jQuery UI accordion.

Thanks a lot t @Sgoldy for pointing me in the right direction here!

How to solve :

I know you bored from this bug, So we are here to help you! Take a deep breath and look at the explanation of your problem. We have many solutions to this problem, But we recommend you to use the first method because it is tested & true method that will 100% work for you.

Method 1

Yes you need a directive and you can handle this more angular way !

In HTML define the directive

<div ui-accordion="accordionData" ></div>

Return promise from your service and pass the promise to the directive.

In controller

$scope.accordionData = myService.getAccordionData();

The ui-accordion directive looks like

.directive('uiAccordion', function($timeout) {
return {
    myAccordionData: '=uiAccordion'
  template: '<div ng-repeat="item in myData"><h3 ng-bind="item.title"></h3><div><p ng-bind="item.data"></p></div></div>',
  link: function(scope, element) {
    scope.myAccordionData.then(function(data) {
      scope.myData = data;

    var generateAccordion = function() {
      $timeout(function() {   //<--- used $timeout to make sure ng-repeat is REALLY finished
          header: "> div > h3"

When your service call succeed then you create your accordion. Here you can define your own accordion-template like

<div ng-repeat="item in myData">
  <h3 ng-bind="item.title"></h3>
     <p ng-bind="item.data"></p>

Template binds with your model data myData. I use ng-repeat inside the template to create accordion-header and accordion-body HTML.

In the generateAccordion method i use $timeout to make sure the ng-repeat is really finished rendering because $timeout will execute at the end of the current digest cycle.

Check the Demo

Method 2

My best practice is to resolve your asynchronous services before controller is initiated.

As you can see in the document, http://docs.angularjs.org/api/ngRoute.$routeProvider

resolve – {Object.=} – An optional map of
dependencies which should be injected into the controller. If any of
these dependencies are promises, the router will wait for them all to
be resolved or one to be rejected before the controller is
instantiated. If all the promises are resolved successfully, the
values of the resolved promises are injected and $routeChangeSuccess
event is fired. If any of the promises are rejected the
$routeChangeError event is fired.

Your controller and view won’t be even started before your service is resolved or rejected.

There is a good video tutorial about this, https://egghead.io/lessons/angularjs-resolve

In your case, you can config routes like the following

var myApp = angular.module('myApp', ['ngRoute']);
myApp.config(function($routeProvider) {
  $routeProvider.when('/', {
    templateUrl: 'main.html',
    controller: orderController,
    resolve: {
      categories: function(orderService) {
        return orderService.getProductCategoriesWithProducts();
      user: function(userService) {
        return userService.getCurrentUser();

Then, with your controller

app.controller('orderController', function($scope, categories, user) {
   //categories and user is always here, so use it.

I have also found a similar question and answer here

Note: Use and implement method 1 because this method fully tested our system.
