reload=true 在@click 函数中不起作用

reload=true not working in @click function

我正在研究货币转换器。我在单击 link 时调用方法,在方法成功后希望它重新加载。但重新加载根本不起作用。货币存储在 cookie 中,如果我手动刷新页面,它也会在导航栏中更新,但我希望它在方法完成后自动重新加载。

这是导航栏中的代码..

<b-dropdown position="is-bottom-left" aria-role="menu">
  <template #trigger>
    <a class="navbar-item font-bold" role="button">
      {{currency}}
      <b-icon icon="menu-down"></b-icon>
    </a>
  </template>
  <b-dropdown-item v-for="(item, index) in currencies" :key="index" has-link aria-role="menuitem">
    <a class="no-underline" @click="setCurrency(item.iso, (reload = true))"><span class="text-pink-600 font-bold">{{item.fullname}} ({{item.iso}})</span></a>
  </b-dropdown-item>
</b-dropdown>

这是方法。

methods: {
  setCurrency(newcurrency) {
    this.$cookies.set(`usercurrency`, newcurrency, {
      path: '/',
      maxAge: 60 * 60 * 24 * 7
    })
  // window.location.href = '/'
  }
}

我想在设置 cookie 后使用 window.location.href = '/' 但我不能这样做,因为我在创建的挂钩中使用相同的方法,如下面的代码根据用户国家/地区设置货币,它会说 window 未定义。

created() {
  const isCurrency = this.$cookies.get('usercurrency')
  const isUserCountry = this.$cookies.get('usercountry')
  if (isCurrency === undefined) {
    if (isUserCountry === undefined) {
      fetch('https://ipinfo.io/json?token=*********')
        .then((response) => response.json())
        .then((jsonResponse) => {
          const country = jsonResponse.country
          this.$cookies.set(`usercountry`, country, {
            path: '/',
            maxAge: 60 * 60 * 24 * 7,
          })
          var CurrencyParam
          switch (country) {
            case 'IN':
            case 'NP':
              CurrencyParam = 'INR'
              break
            case 'US':
              CurrencyParam = 'USD'
              break
            case 'AU':
              CurrencyParam = 'AUD'
              break
            case 'CA':
              CurrencyParam = 'CAD'
              break
            case 'GB':
              CurrencyParam = 'GBP'
              break
            case 'AE':
              CurrencyParam = 'AED'
              break
            case 'RU':
              CurrencyParam = 'RUB'
              break
            case 'JP':
              CurrencyParam = 'JPY'
              break
            case 'SG':
              CurrencyParam = 'SGD'
              break
            case 'FR':
            case 'FI':
            case 'DE':
            case 'GR':
            case 'HU':
            case 'IT':
            case 'LT':
            case 'MT':
            case 'NL':
            case 'NO':
            case 'PL':
            case 'PT':
            case 'RO':
            case 'RS':
            case 'ES':
            case 'SE':
            case 'CH':
            case 'UA':
              CurrencyParam = 'EUR'
              break
            default:
              CurrencyParam = 'USD'
          }
          this.setCurrency(CurrencyParam)
        })
        .catch((error) => {
          console.log(error)
          this.setCurrency('USD')
        })
    }
  }
},

快速解决方案可能是将 reload 作为可选参数传递给 setCurrency

methods: {
    setCurrency(newcurrency, reload) {
        this.$cookies.set(`usercurrency`, newcurrency, {
            path: '/',
            maxAge: 60 * 60 * 24 * 7
        })
        if (reload) window.location.href = '/'
    }
}
