[AngularJS]17. Form validation, ng-options

Use the fancy directives you just learned to validate the new review form.

Turn off default HTML validation.

<form name="reviewForm" ng-controller="ReviewController as reviewCtrl" ng-submit="reviewCtrl.addReview(product)" novalidate>

Mark stars & author as required fields.

复制代码
                <select ng-model="reviewCtrl.review.stars" class="form-control" ng-options="stars for stars in [5,4,3,2,1]" title="Stars" required >
                  <option value="">Rate the Product</option>
                </select>
              </fieldset>
              <fieldset class="form-group">
                <textarea ng-model="reviewCtrl.review.body" class="form-control" placeholder="Write a short review of the product..." title="Review"></textarea>
              </fieldset>
              <fieldset class="form-group">
                <input ng-model="reviewCtrl.review.author" type="email" class="form-control" placeholder="jimmyDean@example.org" title="Email" required />
              </fieldset>
复制代码

Prevent the submit if not $valid.

<form name="reviewForm" ng-controller="ReviewController as reviewCtrl" ng-submit="reviewForm.$valid&&reviewCtrl.addReview(product)" novalidate>
