Unconventional method, monitor the ng-model in your controller:
<input type="text" ng-model="myText">
Controller:
$scope.$watch('myText', function() {
// add code here to remove any non-alphabetic characters
if ($scope.myText ... regex to search for ... ) {
// remove the non-alphabetic characters
}
})
Optimal approach, implement a $parser in a directive. To avoid redundancy, refer to the insightful response given by @pkozlowski.opensource at this link:
Avoid using ng-change as it may lead to issues. Refer to AngularJS - reset of $scope.value doesn't change value in template (random behavior)
Update: ng-pattern can also be employed to set a regex that restricts input in the field. For more information, visit the forms "cookbook" page.
