这篇博客展示了如何使用AngularJS实现一个购物车的功能，包括添加商品、删除商品、清空购物车、计算商品总数和总价。通过ng-repeat指令遍历商品列表，并结合ng-model双向绑定实现数量修改，ng-change监听数量变化，ng-click处理移除和清空操作。

<!DOCTYPE html>
<html ng-app="myApp">
<head>
<meta charset="utf-8" />
<title></title>
<script type="text/javascript" src="js/angular.min.js" ></script>
<script>

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

myApp.controller("myCrtl",function($scope,$http){

//自定义数据
$scope.list = [
{ gid: 001, gname: "手机", gnum: 3,gprice: 1000, gcount: 3000 },
{ gid: 002, gname: "电脑", gnum: 3, gprice: 2000, gcount: 6000 },
{ gid: 003, gname: "电视", gnum: 6, gprice: 500, gcount: 3000 }
]

//删除方法
$scope.remove = function(index){
if(confirm("是否确认移除?")){
$scope.list.splice(index,1);
}
}

//清空购物车的方法
$scope.removes = function(){
if(confirm("确定要清空购物车?")){
$scope.list = [];
}
}

//商品总数方法
$scope.nums = function(){
var num = 0;
for(var i = 0;i<$scope.list.length;i++){
num += $scope.list[i].gnum;
}
return num;
}

//商品总价方法
$scope.prices = function(){
var price = 0;
for(var i = 0;i<$scope.list.length;i++){
price += $scope.list[i].gprice * $scope.list[i].gnum;
}
return price;
}

//
$scope.chan = function(index){
if($scope.list[index].gnum <= 0){
if(confirm("确定要删除此商品吗？")){
$scope.list.splice(index,1);
}else{
$scope.list[index].gnum = 1;
}
}
}

//定义一个变量
$scope.order = "";

})
