Dynamic content



I’ve been using the following script to create update-able content:

function loadXMLDoc()
  xmlhttp=new XMLHttpRequest();
  if (xmlhttp.readyState==4 && xmlhttp.status==200)

Then i have created a button in the specific template like this:

  <a class="item" onclick="loadXMLDoc()">
<div id="myDiv"></div>

All of this works just fine, but now i want it to load the script when i enter the page instead of the user having to press a button. How would i best do that?


Probably the best way is to use a resolve, I’m using them extensively with ui-router in order to resolve HTTP requests.

It works best when you have a controller that loads for the respective page the user is navigating to.

In my router:

$stateProvider.state('app.new_survey', {
  url: '/surveys/new',
  views: {
    menuContent: {
      templateUrl: 'templates/surveys/main.html',
      controller: 'SurveyCtrl',
      resolve: {
        survey: function(Survey, $q) {
          var defer;
          defer = $q.defer();
          Survey.query(function(response) {
            return defer.resolve(response);
          return defer.promise;

Should note that Survey is an ngResource.

And, inside the SurveyCtrl, I require the survey object I’m resolving as a dependency:

angular.controller("SurveyCtrl", function($scope, $state, survey) 

This way, whenever SurveyCtrl is instantiated, the resource is ready.
