Vue.js 轻量级 JavaScript 框架
Vue.js 是构建 Web 界面的 JavaScript 库，提供数据驱动的组件，还有简单灵活的 API，使得 MVVM 更简单。
本文实例为大家分享了Vuejs购物车实现代码，供大家参考，具体内容如下
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 class="container">
<template v-if="data.length">
<h3>我的购物车：</h3>
<div class="product">
<div class="item">
<span class="btn btn-default">商品名称</span>
<span class="btn btn-default left">商品单价</span>
<span class="btn btn-default left">商品数量</span>
<span class="btn btn-default left">操作</span>
</div>
<div class="item" style="padding:5%;border: 1px solid black" v-for="item in data">
<span class="btn btn-default">{{item.name}}</span>
<span class="btn btn-default left" style="margin-left: 18%">{{item.price}}</span>
<span>
<em class="btn btn-primary add" v-on:click="add($index)" :class="{off:item.count==11}">+</em>
{{item.count}}
<em class="btn btn-primary reduce" v-on:click="reduce($index)" :class="{off:item.count==1}">-</em>
</span>
<span class="btn btn-danger left" v-on:click="remove(item)">移除</span>
</div>
</div>
<h2>清单：</h2>
<span class="btn btn-primary">商品总价：{{price |currency '$' 2}}</span>
</template>
<template v-else>
<div class="jumbotron">
<h1>您的购物车空了</h1>
<p>是否去重新挑选</p>
<p><a class="btn btn-primary btn-lg" href="#" role="button">重新挑选</a></p>
</div>
</template>
</div>
</body>
<script>
new Vue({
el:'.container',
data:{
data:data
},
computed:{
price:function () {
var price = 0;
for(var i=0;i<this.data.length;i++){
var self = this.data[i];
price += self.count * self.price;
}
return price;
}
},
methods:{
add:function ($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>
