How to access AngularJS variable from template script

My controller:

$scope.totals = totals;

My template (works as expected for html injection):

{{totals}}

But what I need is to access the variable totals in a script in the template, like so:

<script>
  var totals = ????;
  // do stuff with totals
</script>

I've tried $scope.totals, $totals, {{totals}}, etc, with no avail. I would appreciate any insight, thanks!

EDIT:

The following is a jsfiddle of my controller and template. Inside of the template I'm wanting to insert a script that uses the $scope.totals variable.

OP Answer:

I ended up having to use a directive to find the value I wanted. In the controller that set the value I wanted to use I added a directive so that it looked like this:

'use strict';

angular.module('AdminApp')
  .controller('AdminEventsCtrl', function ($scope, collection) {
    $scope.totals = collection;
  }).directive('foo', function(){
    return {
        restrict: 'A',
        link: function(scope, elem, attrs){
            //Use scope.totals here
        }
    }
});

In my template I had the declaration:

<div foo></div>

This gave me the ability to do what I needed with the variable totals.

Special thanks to @jvandemo for helping me arrive at this answer.

First of all, the idea behind AngularJS is to avond situations like that.

In terms of AngularJS you woud probably be better off rethinking your application and use a directive to encapsulate the code you are currently writing in the script tags.

However, that being said, there is a way to access a scope like this:

var $element = $('#elementId');

var scope = angular.element($element).scope();

You can read the documentation for more details.

But as said, it is not a recommended practice in most cases.

Hope that helps!

Update after OP posted jsFiddle:

I created a working jsFiddle for your convenience at http://jsfiddle.net/jvandemo/hYnBa/1/

Since your example has a simple div with an ng-controller attribute, you can access the scope like this:

<script>
    $(document).ready(function(){
        var $element = $('div[ng-controller="AdminEventsCtrl"]');
        var scope = angular.element($element).scope();
        console.dir(scope);
    });
</script>

Here's what happens:

  • You select the element (in this case by using jQuery)
  • You wrap the element as an AngularJS element (exposing extra methods on the element)
  • You call the scope() method on the element
  • You can then access the scope properties e.g. scope.totals

Hope that helps!
