I am facing an issue where I cannot see the character count when the ng-maxlength limit is reached.
var app = angular.module('plunker', []);
app.controller('MainCtrl', function($scope) {
});<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<div ng-app="plunker" ng-controller="MainCtrl">
<form name="form" novalidate>
<input type="text" ng-model="myChar" ng-maxlength="5">
<br>
<h1>Length: {{myChar.length}}</h1>
</form>
</div>Once the maxlength limit is reached, the $modelValue of myChar becomes undefined. However, you can still access the $viewValue property to get the desired result.
var app = angular.module('plunker', []);
app.controller('MainCtrl', function($scope) {
$scope.test = function() {
console.log($scope.form.myChar.$viewValue.length);
}
});<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.5.5/angular.min.js"></script>
<div ng-app="plunker" ng-controller="MainCtrl">
<form name="form" novalidate>
<input type="text" name="myChar" ng-model="myChar" ng-maxlength="5" ng-keyup="test()">
<br>
<h1>Length: {{myChar.length}}</h1>
</form>
</div>Here is an improved version of @John Smith's answer:
To enhance the verification process, you can directly integrate it into your HTML code. By applying CSS styling, you can visually indicate to the user when the input length is invalid:
var app = angular.module('plunker', []);
app.controller('MainCtrl', function($scope) {
});<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.5.5/angular.min.js"></script>
<style>
.red {
color: red;
}
</style>
<div ng-app="plunker" ng-controller="MainCtrl">
<form name="form" novalidate>
<input type="text" name="myChar" ng-model="myChar" ng-maxlength="5">
<br>
<h1 ng-class="{'red': form.myChar.$viewValue.length > 5}">Length: {{form.myChar.$viewValue.length}}</h1>
</form>
