socket.on('connect', function () {
    console.log('connected !', socket.connected);

    function capture() {

目前我正在制作一个电子商务网站。我想将用户的订单数据存储在本地存储上。这是我的代码：

详情.vue

import DataService from '../web_service/services'

export default {

  data () {
    return {
      datas: null,
      url: '/' + this.userId,
      value: 1
    }
  },
  created () {
    DataService.getFindById(this.url)
      .then((res) => {
        this.datas = res.data.data
      })
      .catch((err) => {
        alert('error when fetching API' + err)
      })
  },
  methods: {
    buyNow () {
      let order = {
        product: this.datas.name,
        price: this.datas.price,
        quantity: this.value
      }

      this.$store.commit('addOrder', order)
      this.$router.push('/cart')
