What is the best way to apply a class to an element in an input template using Angular's ngFocus directive, or any directive incorporated in the Ionic Framework?

I'm working with a template that looks like this:

    <label class="item item-input"
           ng-class="{'focus':authData.username.focus}"> <--add class here if input:focus
        <span class="input-label">Username</span>
        <input type="text"
               name="username"
               ng-model="authData.username"
               ng-focus="" <--check if focus
               required ng-minlength="5" ng-maxlength="20">
    </label>

Is there a way to determine if an input field is focused and then apply a class to the label without using an external function in the controller?

Answer №1

<label class="item item-input"
           ng-class="{'focus':focused===true}">
        <span class="input-label">Enter your username</span>
        <input type="text"
               name="username"
               ng-model="userData.username"
               ng-focus="focused=true" ng-blur="focused=false"
               required ng-minlength="5" ng-maxlength="20">
    </label>

Utilize ngFocus and ngBlur directives to track focus changes on an element and update the value of a variable focused accordingly.
