将项目添加到AngularJS的购物车中
[英]Add items to a shopping cart in AngularJS
问题描述
Angular beginner here. 
有角的初学者在这里。 I'm trying to create a shopping cart for college. 我正在尝试为大学创建购物车。 I need to add the name and price in a text input and after clicking a button the item is supposed to be added to a list. 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。 The thing is that whenever I press the button nothing happens, and I'm lost since the console doesn't tell me anything about what could be wrong. 事实是，每当我按下按钮时，都不会发生任何事情，而且我迷失了，因为控制台没有告诉我任何可能出错的信息。 So, here's my code: 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>
And this is my js code: 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 = "";
}
});

1
<input type = "submit" value = "Add" ng-click = "addProduct()">
Needs to be 需要是
<input type = "button" value = "Add" ng-click = "addProduct()">
Submit will submit the form to the server, not exactly what you're looking for I guess. 提交会将表单提交到服务器，而不是我所想的。
Also, bad typo here: 另外，这里的错别字：
<div">
And here (products, not productos): 在这里（产品而不是产品）：
$scope.productos

You have pushed the values to wrong object . 您已将值推入错误的对象。 and also you need to change lot .and your button click should be need write to 并且还需要更改很多。单击按钮应需要写至
$scope.addProduct= function () {
//code
}
So please copy and past my code to instead of your code 因此，请复制并粘贴我的代码，而不是将其粘贴到您的代码中
