How do I access the $scope variable in browser's console using AngularJS?

Question

I would like to access my $scope variable in Chrome\'s JavaScript console. How do I do that?

I can neither see $scope nor the name of my mo

Answer 1

I've used angular.element($(".ng-scope")).scope(); in the past and it works great. Only good if you have only one app scope on the page, or you can do something like:

angular.element($("div[ng-controller=controllerName]")).scope(); or angular.element(document.getElementsByClassName("ng-scope")).scope();

Answer 2

For only debugging purposes I put this to the start of the controller.

   window.scope = $scope;

  $scope.today = new Date();

And this is how I use it.

then delete it when I am done debugging.

To add and enhance the other answers, in the console, enter $($0) to get the element. If it's an Angularjs application, a jQuery lite version is loaded by default.

If you are not using jQuery, you can use angular.element($0) as in:

angular.element($0).scope()

To check if you have jQuery and the version, run this command in the console:

$.fn.jquery

If you have inspected an element, the currently selected element is available via the command line API reference $0. Both Firebug and Chrome have this reference.

However, the Chrome developer tools will make available the last five elements (or heap objects) selected through the properties named $0, $1, $2, $3, $4 using these references. The most recently selected element or object can be referenced as $0, the second most recent as $1 and so on.

Here is the Command Line API reference for Firebug that lists it's references.

$($0).scope() will return the scope associated with the element. You can see its properties right away.

Some other things that you can use are:

• View an elements parent scope:

$($0).scope().$parent.

• You can chain this too:

$($0).scope().$parent.$parent

• You can look at the root scope:

$($0).scope().$root

• If you highlighted a directive with isolate scope, you can look at it with:

$($0).isolateScope()

Just assign $scope as a global variable. Problem solved.

app.controller('myCtrl', ['$scope', '$http', function($scope, $http) {
    window.$scope = $scope;
}

We actually need $scope more often in development than in production.

Mentioned already by @JasonGoemaat but adding it as a suitable answer to this question.

Answer 5

I usually use jQuery data() function for that:

$($0).data().$scope

The $0 is currently selected item in chrome DOM inspector. $1, $2 .. and so on are previously selected items.

Somewhere in your controller (often the last line is a good place), put

console.log($scope);

If you want to see an inner/implicit scope, say inside an ng-repeat, something like this will work.

<li ng-repeat="item in items">
   ...
   <a ng-click="showScope($event)">show scope</a>
</li>

Then in your controller

function MyCtrl($scope) {
    ...
    $scope.showScope = function(e) {
        console.log(angular.element(e.srcElement).scope());
    }
}

Note that above we define the showScope() function in the parent scope, but that's okay... the child/inner/implicit scope can access that function, which then prints out the scope based on the event, and hence the scope associated with the element that fired the event.

@jm-'s suggestion also works, but I don't think it works inside a jsFiddle. I get this error on jsFiddle inside Chrome:

> angular.element($0).scope()
ReferenceError: angular is not defined
