Working on an Angular form where users advance to the next step by clicking a button, but it remains disabled until all fields are valid.
I'm wondering how I can implement a custom class to highlight incomplete fields when the user tries to move to the next step. Should I use $scope.watch or is there a simpler method to identify the invalid form elements?
Based on my understanding of the question, you can find a helpful example in the documentation that demonstrates what you are trying to achieve: http://docs.angularjs.org/api/ng.directive:form
The example shows how a message is displayed when a field is left empty.
<form name="myForm" ng-controller="Ctrl">
userType: <input name="input" ng-model="userType" required>
<span class="error" ng-show="myForm.input.$error.required">Required!</span>
