我是初学者。我想为大学设计一个购物车。我需要在文本输入中添加名称和价格，单击按钮后，该项目应添加到列表中。问题是，每当我按下按钮时，什么都不会发生，我也会不知所措，因为控制台没有告诉我什么可能是错误的。下面是我的代码：

<!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>

您将值推送到了错误的对象。而且你还需要改变很多。你的按钮点击应该是需要写

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

因此，请复制我的代码并将其传递给，而不是您的代码

HTML

而且

nombre

应该是

name

谢谢，我把submit改为button，把form改为div，虽然没有解决我的问题。另外两个错误没有出现在我的原始代码中，因为我的程序最初不是用英语编写的，所以我不得不翻译它并删除一些与问题无关的样式。按钮单击是不调用，因为angular js需要调用

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

…看到我的答案了吗，它确实解决了我的问题。我将我的函数声明更改为您建议的，并且工作得很好。非常感谢你。

<input type = "submit" value = "Add" ng-click = "addProduct()">

<input type = "button" value = "Add" ng-click = "addProduct()">

 <div">

$scope.productos

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