html:
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>我的vue购物车</title> <link rel="stylesheet" href="css/bootstrap.min.css"> <link rel="stylesheet" href="css/style.css"> <script src="js/vue.js"></script> <script src="js/data.js"></script> </head> <body> <div> <template v-if="data.length"> <h3>我的购物车：</h3> <div> <div> <span>商品名称</span> <span>商品单价</span> <span>商品数量</span> <span>操作</span> </div> <div v-for="item in data"> <span>{{item.name}}</span> <span>{{item.price}}</span> <span> <em v-on:click="add($index)" :class="{off:item.count==11}">+</em> {{item.count}} <em v-on:click="reduce($index)" :class="{off:item.count==1}">-</em> </span> <span v-on:click="remove(item)">移除</span> </div> </div> <h2>清单：</h2> <span>商品总价：{{price |currency '$' 2}}</span> </template> <template v-else> <div> <h1>您的购物车空了</h1> <p>是否去重新挑选</p> <p><a href="#" role="button">重新挑选</a></p> </div> </template> </div> </body> <script> new Vue({ el:'.container', data:{ data:data }, computed:{ price:function () { var price = 0; for(var i=0;i<this.data.length;i++){ var self = this.data[i]; price += self.count * self.price; } return price; } }, methods:{ add:function ($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); } } }) </script> </html>
css:
h3{ text-align: center; } .left{ margin-left: 14%; } .item{ text-align: center; padding: 3%; } .add{ margin-left: 15%; } .off{ background-color: lightgrey; border: 1px solid lightgrey; }
