How do I bind to list of checkbox values with AngularJS?

Question

I have a few checkboxes:

Answer 1

Using a string of $index can help to use a hashmap of selected values:

This way the ng-model object gets updated with the key representing the index.

$scope.someObject = {};

After a while $scope.someObject should look something like:

$scope.someObject = {
     0: true,
     4: false,
     1: true
};

This method won't work for all situations, but it is easy to implement.
