</body>
<script>
 new Vue({
 el:'.container',
 data:{
 data:data
 },
 computed:{
 price:function () {
 var price = 0;
 for(var i=0;i<this.data.length;i++){
 var self = this.data[i];
 price += self.count * self.price;
 }
 return price;
 }
 },
 methods:{
 add:function ($index) {
 var self = this.data[$index];
 if(self.count >10){
 return false;
 }
 self.count++;
 },
 reduce:function($index){
 var self = this.data[$index];
 if(self.count <= 1){
 return false
 }
 self.count--;
 },
 remove:function(item){
 this.data.$remove(item);
