我正在使用CodeSchool的“使用角度塑造”教程中的指令,并且我对某些语法的工作方式感到困惑.例如,在下面的代码中,比如ng-repeat =“store in store.products”,即使单个表达式之前没有声明(据我所知),它们也使用同一个单词的单数和复数版本.这整个过程中有几次.
Angular能否以这种方式解释作者的意图？！
index.html的：
<!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="list-group" ng-controller="StoreController as store">
<!-- Product Container -->
<div class="list-group-item" ng-repeat="product in store.products">
<h3>{{product.name}} <em class="pull-right">{{product.price | currency}}</em></h3>
<!-- Image Gallery -->
<div class="gallery">
<div class="img-wrap">
<img ng-src="{{product.images[0]}}" />
</div>
<ul class="img-thumbnails clearfix">
<li class="small-image pull-left thumbnail" ng-repeat="image in product.images">
<img ng-src="{{product.images[0]}}" />
</li>
</ul>
</div>
</div>
</body>
</html>
app.js：
(function() {
var app = angular.module('gemStore',[]);
app.controller('StoreController',function() {
this.products = gems;
});
var gems = [{
name: 'Azurite',description: "Some gems have hidden qualities beyond their luster,beyond their shine... Azurite is one of those gems.",shine: 8,price: 110.50,rarity: 7,color: '#CCC',faces: 14,images: [
"images/gem-02.gif","images/gem-05.gif","images/gem-09.gif"
]
},{
name: 'Bloodstone',description: "Origin of the Bloodstone is unknown,hence its low value. It has a very high shine and 12 sides,however.",shine: 9,price: 22.90,rarity: 6,color: '#EEE',faces: 12,images: [

]
},{
name: 'Zircon',description: "Zircon is our most coveted and sought after gem. You will pay much to be the proud owner of this gorgeous and high shine gem.",shine: 70,price: 1100,rarity: 2,color: '#000',faces: 6,images: [

]
}];
})();
