Get Angular scope variable length

Question

I need to get the length of Angular model $scope. My code alerts undefined.
But scope has a value when I alert scope without length

alert($scope.comppostal.length)

How to check the length? Content of $scope.comppostal is 12345

@Ervikas. Thats a number. How can you use .length for a number? — Zee

You are getting the undefined as $scope.comppostal is a number. You need to convert it to string.

Use

alert((''+$scope.comppostal).length)

var a = 12345;
alert(('' + a).length);

is this ' ' effect on my length

@Ervikas, '' is empty string, hence no impact
