Vue解決購物車

Vue 易用，靈活，高效。
<div id="app">
{{ message }}
</div>
<script src="https://cdn.jsdelivr.net/npm/vue"></script>
</body>
<script>
var app = new Vue({
el: '#app',
data: {
message: 'Hello Vue!'
}
})
</script>這就是一個最簡單的Vue。
靈活-漸進式。
Vue 的基礎指令介紹：
指令使用 v-model v-text v-show v-if v-bind v-for v-on
v-model 的主要應用場景是 表單輸入雙向繫結。
v-text 文字渲染 等同於 {{ }} ,
v-show dom的顯示和隱藏
v-if 判斷
v-bind 給dom元素繫結屬性。
v-for 迴圈
v-on 事件繫結
過濾器Filter
元件 Component
類似django，beego 的template的複用
下面是購物車程式碼
