有角的初学者在这里。我正在尝试为大学创建购物车。我需要在文本输入中添加名称和价格，单击按钮后，该项目应该添加到列表中。问题是，每当我按下该按钮时，都不会发生任何事情，而且我迷失了方向，因为控制台没有告诉我任何可能出错的信息。所以，这是我的代码：

<!DOCTYPE html>
<html ng-app = "myApp">
<head>
    <title>Shopping Cart</title>
    <script src = "https://ajax.googleapis.com/ajax/libs/angularjs/1.3.14/angular.min.js">     </script>
    <script src = "app.js"></script>        
</head>
<body ng-controller = "myShoppingCart">

            <h1>Add to cart</h1>
            <form >
                    <p>Product: <input type = "text" ng-model = "nameProduct"></p>
                    <p>Price: <input type = "number" min = "0" step = "any" ng-model = "priceProduct"></p>
                    <input type = "submit" value = "Add" ng-click = "addProduct()">
            </form>

        </div>

        <div">
            <ul>
                <li ng-repeat = "product in products">
                    <span>{{product.name}}</span>
                    <span>{{product.price}}</span>
                    <span><input type = "number" min = "0" placeholder = "0" value = "0" ng-model = "amount"></span>
                    <span>{{product.price*amount}}</span>
                </li>
            </ul>
        </div>
  </body>
</html>

这是我的js代码：

var myApp = angular.module("myApp", []);

myApp.controller('myShoppingCart', function($scope) {

 $scope.products = [];

 function addProduct() {

    $scope.productos.push({nombre:$scope.nameProduct, price:$scope.priceProduct});
    $scope.nameProduct = "";
    $scope.priceProduct = "";
 }

});

您已将值推入错误的对象。并且还需要更改很多。单击按钮应需要写至

 $scope.addProduct= function () {
//code
}

因此，请复制并粘贴我的代码，而不是将其复制到

的HTML

<!DOCTYPE html>
<html ng-app = "myApp">
<head>
    <title>Shopping Cart</title>
    <script src = "https://ajax.googleapis.com/ajax/libs/angularjs/1.3.14/angular.min.js">     </script>
    <script src = "app.js"></script>        
</head>
<body ng-controller = "myShoppingCart">

            <h1>Add to cart</h1>
            <form >
                    <p>Product: <input type = "text" ng-model = "nameProduct"></p>
                    <p>Price: <input type = "number" min = "0" step = "any" ng-model = "priceProduct"></p>
                    <input type = "submit" value = "Add" ng-click = "addProduct()">
            </form>

        </div>

        <div>
            <ul>
                <li ng-repeat = "product in products">
                    <span>{{product.name}}</span>
                    <span>{{product.price}}</span>
                    <span><input type = "number" min = "0" placeholder = "0" value = "0" ng-model = "amount"></span>
                    <span>{{product.price*amount}}</span>
                </li>
            </ul>
        </div>
  </body>
</html>

和JS代码

var myApp = angular.module("myApp", []);

myApp.controller('myShoppingCart', function($scope) {

 $scope.products = [];

$scope.addProduct= function () {

    $scope.products.push({name:$scope.name, price:$scope.priceProduct});
    $scope.nameProduct = "";
    $scope.priceProduct = "";
 }

});
