AngularJS <input> validation with no enclosing <form>
You may use the ng-form angular directive (see docs here) to group anything, even outside a html form. Then, you can take advantage from angular FormController.
<div class="form-group" ng-form name="myForm"> <input name="myInput" type="text" class="form-control" ng-model="bindTo" ng-maxlength="5"> <span class="error" ng-show="myForm.myInput.$error.maxlength">Too long!</span></div>
Building on Silvio Lucas' answer, if you are iterating in a loop and need to be able to interpolate form names and valid states:
<div name="{{propertyName}}" ng-form="" class="property-edit-view" ng-class="{ 'has-error': {{propertyName}}.editBox.$invalid, 'has-success': {{propertyName}}.editBox.$valid && {{propertyName}}.editBox.$dirty && propertyValue.length !== 0 }" ng-switch="schema.type"> <input name="editBox" ng-switch-when="int" type="number" ng-model="propertyValue" ng-pattern="/^[0-9]+$/" class="form-control"> <input name="editBox" ng-switch-default="" type="text" ng-model="propertyValue" class="form-control"> <span class="property-type" ng-bind="schema.type"></span></div>
