The left angular character is malfunctioning

Within my Angular view, there is a textarea set up like this:

<div class="form-group">
    <label>Descrição</label>
    <textarea name="area" ng-minlength="30" class="form-control" ng-model="produtos.descricao" id="descricao" type="text" placeholder="descricao"></textarea>
    <span ng-if="check()">Caracteres restantes: {{produtos.descricao.length}}</span>
</div>

In the controller section, I have the following code:

$scope.produtos = [];
$scope.minLength = 30;
console.log($scope.minLength);

$scope.check = function(){
    return ($scope.produtos.descricao.length < 30);
}

If the check returns true, shouldn't the ng if condition work?

Answer №1

Your code attempts to access

$scope.products.description.length
. However, you have initialized $scope.products = [] during initialization. There is no property named description in $scope.products. As a result, when you try to access description.length, an error will be thrown and the execution of the code will fail. You can view this error in the developer console. This is why the check() function is not running and causing errors. Additionally, ng-if may not work as expected.

Answer №2

Your code may be a bit confusing as it is not clear whether $scope.produtos is an array or an object. However, I believe I understand your requirement - you want to display

<span ng-if="check()">Remaining characters: {{produtos.descricao.length}}</span>
when the text box has less than 30 characters. You can try the code snippet below to solve this issue.

<div class="form-group">
  <label>Description</label>
  <textarea name="area" ng-minlength="30" class="form-control" ng-model="something" id="descricao" type="text" placeholder="description"></textarea>
  <span ng-if="something.length<30">Remaining characters: {{something.length}}</span></div>
