Remove input requirement with anguljar

Question

I have a question with Angularjs, I am making a registration form, and has a certain form that I am doing a validation and has an option to insert multiple phones, it enters the phones clears the input data and goes to a list with angular repeat.

My doubt is, when I enter at least 1 phone, it will remove the mandatory field (required), or set the field as valid.

I tried to use the $setValidity(); but it wasn’t also what I’m doing wrong?

Excerpt from the code I’m using

var $formElem,$formScope;
$formElem = angular.element(formCliente);
$formScope = $formElem.scope();
$formScope.formCliente.telefone.$setValidity('required', false);

Answer 1

You can use the ng-required , that takes an expression and adds or not the required according to the result of its variable.

<input type="number" data-ng-model="telefoneInput" ng-required="temAlgumTelefoneNaLista"/> 

whereas his $scope.temAlgumTelefoneNaLista = (suaListaDeTelefones.length > 0);
