Tips for transferring information from controller JavaScript to view JavaScript within AngularJS

Currently, I am working on an angularJS application where I retrieve data from a REST service within the controller. The retrieved data is then passed to the view using $scope. However, I encountered an issue when trying to use this data in my in-page JavaScript. Despite attempting to simply use the variable name or {{variable_name}}, it did not work as expected. Any suggestions on how I can achieve this?

Below is a snippet of code from my controller:

 $scope.requests = null;

  var url = 'my_url';

    $http.get(url).then(function(response) 
        {
          $scope.requests = response.data;


       if (response.data.status && response.data.message)
         {
            var status = response.data.status + '!'; 
            var message = response.data.message;

             showAlert(status,message);


          }

      return;

        }).catch(function(response) 
        {

          showAlert('danger!','Some error occured. Please try again.');
        });

Furthermore, below is the in-page JavaScript code:

<script>
$(document).ready(function() { 

    /*
                date store today date.
                d store today date.
                m store current month.
                y store current year.
            */
            var date = new Date();
            var d = date.getDate();
            var m = date.getMonth();
            var y = date.getFullYear();

            /*
                Initialize fullCalendar and store into variable.
                Why in variable?
                Because doing so we can use it inside other function.
                In order to modify its option later.
            */

    $('#calendar').fullCalendar({
        // put your options and callbacks here
             header: {
        left: 'prev,next today',
        center: 'title',
        right: 'month,agendaWeek,agendaDay'
        },
            defaultView: 'month', 
            /*
                    selectable:true will enable user to select datetime slot
                    selectHelper will add helpers for selectable.
                */
            selectable: false,
            selectHelper: false,







                /*
                    editable: true allow user to edit events.
                */
                editable: false,
                /*
                    eventStartEditable: false doesnt allow the dragging of events
                */
                eventStartEditable: false,

                /*
                eventOverlap: false doesnot allow overlapping of events
                */
                eventOverlap: false,
                /*
                    events is the main option for calendar.
                    for demo we have added predefined events in json object.
                */

    /*  var events = requests.map(function(obj, index)
                {
                if (obj.accepted == 'no' ) return false;
                return { id : obj.id, start : obj.start, end : obj.end }
                })*/




}); 
});
</script>

<div id='calendar'></div>

The {{requests}} works for printing out the data, however, it cannot be used within the <script> </script> tags. I am specifically looking to utilize it within the script tags.

Answer №1

When working with Angular, it is recommended to utilize the $window service in your controller to set a variable on the $window object. This allows the script tag to easily check for window.requestsVariable. Keep in mind that you will need to manage the asynchronous nature of the request as the variable will remain empty until the request is complete.

Additionally, instead of following this approach, consider simplifying the jQuery code by integrating it into the linking function of an Angular directive for the calendar, as suggested by andrew.butkus.

Answer №2

To make a variable accessible globally, declare it as 'var global' outside the controller. Within the controller, assign a value to this global variable and then you can easily access it in your Jquery onready function.
