Using Vue to make a shopping cart function is just a test version, focusing on the function implementation, the interface is not good, and the data is also simulation data
Don’t say so much, go straight to the code
<template>
<div>
Select all < input type = "check box" V-model = "checkall" @ change = "check_ all()">
<div v-for="(item,index) in mylist" :key="index">
<span>{{item.oname}}</span><input type="checkbox" v-model="item.this_all" @change="check_list(index)">
<p v-for="(goods,nindex) in item.newlist" :key="nindex">
<input type="checkbox" v-model=" goods.check_ one" @change="click_ input(index,nindex)">{{ goods.newname }}--{{ goods.price }}Yuan
</p>
</div>
<p>Total price: {allprice}}</p>
< button @ Click = "btn()" > submit order < / button >
</div>
</template>
