I was trying to count the length of a string($scope.count = $scope.str.lenght). But, when there is a space at the end of the string its not being counted until there is a character after the space.
Example:
"Hello " = 5,
"Hello u" = 7
Any idea why is it designed in this way?
How can I count the space at the end of the string?
By default Angular will trim the trailing spaces on ngModel. To override this behaviour add:
ng-trim="false"
(function() {
'use strict';
angular.module('myApp', []);
angular.module('myApp').controller('MyController', MyController);
MyController.$inject = [];
function MyController() {
var main = this;
main.someText = 'abcde';
}
}());<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<body ng-app="myApp">
<div ng-controller="MyController as main">
<input type="text" ng-model="main.someText" ng-trim="false">
{{main.someText.length}}
</div>
</body>May be your having the problem with angular ngModel not for the Javascript. Because it is working correct in javascript
console.log("hello ".length)
console.log("hello u".length)In Angularjs I would suggest @giovani answer
"Hello ".lengthget true output! insert some code please.ng-trim="false"
