于伊!我的代码中存在一些问题:
这是我的index.html文件:
<body ng-app="myApp" ng-controller="MainController">
<nav class="navbar navbar-default">
<div class="container-fluid">
<!-- Brand and toggle get grouped for better mobile display -->
<div class="navbar-header">
<a class="navbar-brand" href="#">diyetSahovatKafe</a>
</div>
</div>
</nav>
<div class="main">
<div class="container">
<div class="row">
<div class="col-md-5">
<ul>
<li ng-repeat="item in items.data" id="item{{item.id}}">
<a href="#">{{item.title}}</a>
<img ng-src="{{ item.image }}" />
<button ng-click="addItem(item)">Add Me</button>
</li>
</ul>
<p>Cart:</p>
<ul>
<li ng-repeat="item in cart">
<a href="#">{{item.title}} | Count: {{item.count}}</a>
<a ng-click="deleteItem(item)" class="delete-item">X</a>
</li>
</ul>
</div>
</div>
</div>
</div>
结束这是我的app.js文件:
var app = angular.module('myApp', []);
和控制器文件:
app.controller('MainController', ['$scope', function ($scope, items) {
$scope.items = items;
$scope.cart = [];
$scope.deleteItem = function(item) {
var cart = $scope.cart;
var match = getMatchedCartItem(item);
if (match.count > 1) {
match.count -= 1;
return;
}
cart.splice(cart.indexOf(item), 1);
}
$scope.addItem = function(item) {
var match = getMatchedCartItem(item);
if (match) {
match.count += 1;
return;
}
var itemToAdd = angular.copy(item);
itemToAdd.count = 1;
$scope.cart.push(itemToAdd);
}
function getMatchedCartItem(item) {
return $scope.cart.find(function(itm) {
return itm.id === item.id
});
}
}]);
.factory = ("items", function() {
var items = {};
items.data = [{
id: 1,
title: "Item 1",
image: "img/item01.jpg"
}, {
id: 2,
title: "Item 2",
image: "img/item02.jpg"
}, {
id: 3,
title: "Item 3",
image: "img/item03.jpg"
}, {
id: 4,
title: "Item 4",
image: "img/item04.jpg"
}];
return items;
});
运行代码时没有任何内容,请检查我的代码并解释我的错误,谢谢!
答案 0 :(得分:0)
您在:
中有额外的;
和=
个字符
}]); // end of MainController
.factory = ("items", function() {
您忘了注入items
:
app.controller('MainController', ['$scope', function ($scope, items) {
那就是说,我怀疑你有另一个错误,这在这里是看不到的,因为有了可见的东西,你应该得到像Uncaught SyntaxError: Unexpected token .
这样的东西,用于在分号后写一个点。
