先看运行效果：
具体代码如下：
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>www.jb51.net angular可删除与计算总额的购物车</title>
<script src="angular.min.js"></script>
<style>
table{
width: 500px;
height: 300px;
border-collapse: collapse;
text-align: center;
}
td{
border: 1px solid black;
}
</style>
<script>
var myapp=angular.module("myapp",[]);
myapp.controller("myCtrl",function ($scope) {
$scope.goods=[{
gname:"iphone8",
num:"3",
price:"999"
},{
gname: "iphone7",
num: "4",
price: "599"
},{
gname: "iphone6",
num: "5",
price: "499"
},{
gname: "iphone5",
num: "6",
price: "399"
}
];
$scope.allSum=function () {
var allPrice=0;
for(var i=0;i<$scope.goods.length;i++){
allPrice+=$scope.goods[i].price*$scope.goods[i].num;
}
return allPrice;
};
$scope.remove=function (index) {
if(confirm('确定移除此项嘛？')){
$scope.goods.splice(index,1);
}
if($scope.goods.length==0){
alter('你的购物车为空');
}
};
})
</script>
</head>
