[AngularJS]3. ng-hide and ng-show

1. Use a directive to ensure that we can only see the "Add to Cart" button if the canPurchase property is true.

<button ng-show="store.product.canPurchase">Add to Cart</button>

 

2. Our first gem is so popular that we've run out of stock already! Well, Flatlander gems are pretty rare, so it shouldn't be a big surprise. Luckily there is a soldOut property to our gem. When a gem issoldOut, hide the .product element.

<div class="product row" ng-hide="store.product.soldOut">

 

<!DOCTYPE html>
<html ng-app="gemStore">
  <head>
    <link rel="stylesheet" type="text/css" href="bootstrap.min.css" />
    <script type="text/javascript" src="angular.min.js"></script>
    <script type="text/javascript" src="app.js"></script>
  </head>
  <body class="container" ng-controller="StoreController as store">
    <div class="product row" ng-hide="store.product.soldOut">
      <h3>
        {{store.product.name}}
        <em class="pull-right">${{store.product.price}}</em>
      </h3>
      <button ng-show="store.product.canPurchase">Add to Cart</button>
    </div>
  </body>
</html>(function() {var app = angular.module('gemStore', []);

  app.controller('StoreController', function(){
    this.product = gem;
  });

  var gem = 
　　{
    　　name: 'Azurite',
   　　 price: 110.50,
   　　 canPurchase: false,
    　　soldOut: true
  　};
　　


})();
