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

    One caveat to many of these answers: if you alias your controller your scope objects will be in an object within the returned object from scope().

    For example, if your controller directive is created like so: <div ng-controller="FormController as frm"> then to access a startDate property of your controller, you would call angular.element($0).scope().frm.startDate

    To improve on jm's answer...

    // Access whole scope
    angular.element(myDomElement).scope();
    
    // Access and change variable in scope
    angular.element(myDomElement).scope().myVar = 5;
    angular.element(myDomElement).scope().myArray.push(newItem);
    
    // Update page to reflect changed variables
    angular.element(myDomElement).scope().$apply();
    

    Or if you're using jQuery, this does the same thing...

    $('#elementId').scope();
    $('#elementId').scope().$apply();
    

    Another easy way to access a DOM element from the console (as jm mentioned) is to click on it in the 'elements' tab, and it automatically gets stored as $0.

    angular.element($0).scope();

    If you have installed Batarang

    Then you can just write:

    $scope
    

    when you have the element selected in the elements view in chrome. Ref - https://github.com/angular/angularjs-batarang#console

    This requires jQuery to be installed as well, but works perfectly for a dev environment. It looks through each element to get the instances of the scopes then returns them labelled with there controller names. Its also removing any property start with a $ which is what angularjs generally uses for its configuration.

    let controllers = (extensive = false) => {
                let result = {};
                $('*').each((i, e) => {
                    let scope = angular.element(e).scope();
                    if(Object.prototype.toString.call(scope) === '[object Object]' && e.hasAttribute('ng-controller')) {
                        let slimScope = {};
                        for(let key in scope) {
                            if(key.indexOf('$') !== 0 && key !== 'constructor' || extensive) {
                                slimScope[key] = scope[key];
                            }
                        }
                        result[$(e).attr('ng-controller')] = slimScope;
                    }
                });
    
                return result;
            }

    Put a breakpoint in your code at a somewhere close to a reference to the $scope variable (so that the $scope is in the current 'plain old JavaScript' scope). Then your can inspect the $scope value in the console.
