How to use this angularjs method?

We can fetch the data associated with an element’s $scope simply by using the inheritedData() method on the element:

element.inheritedData();

This inheritedData() finds data up the scope chain as it walks up the DOM until it’s found a particular value has been reached.

var app = angular.module('plunker', []);

app.controller('MainCtrl', function($scope) {
  $scope.name = 'World';
  $scope.displayForm = function(e){
    var form = angular.element(e.target)
        .inheritedData('$formController');
    $scope.form_name = form.$name;
  };
});

Here one input text box

<input type="text" name="icontext">

now we will get this using angular.element

angular.element("input[name='icontext']").val();
