I lack familiarity with AngularJS directives because I typically rely on controllers. Can directives be used to set validity on other inputs? Specifically, I am trying to set validity on a certain input text when a button is clicked, but I can't figure out the code to do so.
Below is the HTML code:
<!DOCTYPE html>
<html ng-app="myApp">
<head>
<script src="http://ajax.googleapis.com/ajax/libs/angularjs/1.4.8/angular.min.js"></script>
</head>
<body>
<div class="container">
<div id="login-container">
<div class="form-group">
<span class="glyphicon glyphicon-user"></span>
</div>
<form name="loginForm" novalidate>
<div class="form-group">
dasdas -- {{ loginForm.student_code.$error.codeValidity }}
<input type="text" class="form-control text-center" name="student_code" ng-model="studentCode" placeholder="Enter Exam Code" required />
<span class="errors" id="error-student-code" ng-if="loginForm.student_code.$error.codeValidity">{{ errors }}</span>
</div>
</form>
<login-button form="loginForm"></login-button>
<a href="register"><button class="btn btn-primary">Register</button></a>
</div>
</div>
</body>
</html>
Below is the JS Code:
var app = angular.module("myApp", []);
app.directive('loginButton', loginButton);
loginButton.$inject = ["$http", "$window"];
function loginButton($http, $window){
return {
template: '<button type="button" class="btn btn-primary">Take Exam</button>',
link: function(scope, element, attrs, ctrl){
element.on('click', function(){
form = attrs.form;
form.student_code.$setValidity('codeValidity', true);
scope.errors = "Code is Invalid";
});
}
}
}

PS.
I understand this could be done with controllers, but I am practicing using directives for a better understanding.
