vue写的购物车界面
作者：互联网
丑陋的界面 而且el-col还是没弄懂，样式都加不上 记录一下
支持按店铺分类，以及删除操作(这里应该考虑的挺细的了)
<template>

看了别人的博客 拿来用的js浮点数乘法
Vue.prototype.NumberMul = function(arg1, arg2) {
var m = 0;
var s1 = arg1.toString();
var s2 = arg2.toString();
try {
m += s1.split(".")[1].length;
} catch (e) {}
try {
m += s2.split(".")[1].length;
} catch (e) {}
return (Number(s1.replace(".", "")) * Number(s2.replace(".", "")) / Math.pow(10, m)).toFixed(2);//两位小数
}
