Is there a way to verify in AngularJS whether ng-model contains a string or a numerical value?

In my Angular application, I have written a JavaScript function that checks if the value of a text field is undefined or empty, and it is working properly.

$scope.checkNumber = function(user_answer){
if(user_answer == undefined){
  return false;
}
}

My next challenge is to create a function that can determine whether the value is a string or a number and return a boolean. I am unsure about the correct syntax for Angular JavaScript. Can someone please assist me in solving this issue?

Answer №1

If you want to tackle this the angular way, you can utilize the angular helper functions for a more streamlined approach:

$scope.validateInput = function(user_input){
    if(angular.isUndefined(user_input)){
      return false;                 
    }
    if(angular.isString(user_input)) {
       //perform string validation
    }
    if(angular.isNumber(user_input)) {
       //perform number validation
    }
}

Answer №2

Give it a shot this way

function verifyDataType(input){     
 return typeof input ==="boolean";
}
