Dynamic scope variable assign Angular

Question

I have the name of my form in $scope.model variable and its adding dynamically. I wanted to change the value of the form field according to $scope.model.
For example

 $scope.model = 'form.field.text';
 $scope.[$scope.model]= 'new value';

But i it doesn't change the value of $scope.form.field.text. How can I do this? Here's my plunkr

• john51: I guess it referring wrong model.

In this case you need to use $parse service which is used by Angular internally for exactly this purpose:

function ctrl($scope, $parse) {
 $scope.form = {
 field: {
 text: ''
 }
 };
 $scope.form.field.text = 'Myvalue';
 $scope.model = 'form.field.text';
 $parse($scope.model).assign($scope, 'new value');
 console.log($scope.form.field.text);
}
