Restrict input to only text characters in a textbox using AngularJS

Looking for a way to ensure that users can only input characters into a textbox in my project. Any suggestions on how I can accomplish this?

Answer №1

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.
