Let me share with you the implementation code first. There is a rendering below the code. You can combine the two for reference. Without further ado, the specific code is as follows:

   
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title></title>
<script src="http://code.angularjs.org/1.2.5/angular.min.js"></script>
<style type="text/css">
td,th{
width: 150px;
text-align: left;
}
table{
width: 800px;
}
.num{
width: 70px;
text-align: center;
}
tr td:last-child button {
background-color: red;
}
#foot button{
background-color: red;
}
</style>
</head>
<!--ng-bind是从$scope -> view的单向绑定ng-modle是$scope <-> view的双向绑定
{{}} 与 ng-bind 的区别是后者在加载时用户不会看到渲染之前的东西,前者可能会看到,所以首页一般用后者加载数据
-->
<body ng-app="myApp">
<div ng-controller="VC1">
<table border="" cellspacing="" cellpadding="">
<tr><th>产品编号</th><th>产品名称</th><th>购买数量</th><th>产品单价</th><th>产品总价</th><th>操作</th></tr>
<tr ng-repeat="x in Product" >
<td>{{x.id}}</td>
<td>{{x.name}}</td>
<td>
<button ng-click="reduce($index)">-</button>
<input type="text" class="num" ng-model="x.quantity" ng-change="change($index)" />
<button ng-click="add($index)">+</button> </td>
<td >{{x.price}}</td>
<td>{{x.price * x.quantity}}</td>
<td><button ng-click="remove($index)">移除</button></td></tr>
</table>
<div id="foot"><span>总价:</span><span ng-bind="totalQuantity()"></span><span>购买数量</span>
<span >{{numAll()}}</span> <button ng-click="removeAll()">清空购物车</button> </div>
</div>
</body>
<script type="text/javascript">
var app = angular.module("myApp",[]);
app.controller("VC1",function($scope){
$scope.Product = [{
id: 1000,
name: "iPhone8",

//减少数量
$scope.reduce = function(index){
if( $scope.Product[index].quantity > 1){
$scope.Product[index].quantity--;
}else{
$scope.remove(index);
}
}
//添加数量函数
$scope.add = function(index){
$scope.Product[index].quantity++;
}
//所有商品总价函数
$scope.totalQuantity = function(){
var allprice = 0
for(var i = 0 ; i <$scope.Product.length;i++ ){
allprice += $scope.Product[i].quantity * $scope.Product[i].price;
}
return allprice;
}
//购买总数量函数
$scope.numAll = function(){
var numAlls = 0
for(var i = 0 ; i <$scope.Product.length;i++ ){
numAlls += $scope.Product[i].quantity;
}
return numAlls;
}
//删除当前商品
$scope.remove = function(index){
if(confirm("确定要清空数据吗")){
$scope.Product.splice(index,1)
}
}
//清空购物车
$scope.removeAll = function(){
if(confirm("你确定套清空购物车所有商品吗?")){
$scope.Product = [];
}
}
//解决输入框输入负数时变为1
$scope.change = function(index){
if ( $scope.Product[index].quantity >= 1) {
}else{
$scope.Product[index].quantity = 1;
}
}
$scope.$watch(&#39;Product&#39;,function(oldvalue,newvalue){
console.log(oldvalue);
console.log(newvalue);
})
})
