Vue插件在nuxt服务器加载上工作，但在客户端导航上不起作用(vue-scrollactive)

Question

我有一个Nuxt应用程序，我已经在其中安装了vue-scrollactive作为插件。

我在一个子页面上使用它(如website.com/company)。如果我重新加载website.com/company，插件工作正常--但是，如果我使用nuxt-link从另一个页面(如website.com或website.com/about)加载网站，那么scrollactive插件就不能工作。

更新:这似乎与v-else上出现的fetchState和main标签有关。我使用fetch对虚拟数据进行了测试，它起作用了。

plugins/scrollActive.js

import Vue from 'vue'
import scrollactive from 'vue-scrollactive'
Vue.use(scrollactive)

nuxt.config.js

plugins: [{ src: '~/plugins/scrollActive' }],

pages/company.vue

<div class="flex flex-col h-screen bg-gray-100">

这有点老生常谈，但我更改了没有v-else的主区域，并将v-if="$fetchState.pending === false"和:class="company === {} ? 'hidden' : 'block'"添加到一个包含数据区域的div中。目前有效，但并不理想。

<!-- Main area -->
    <div v-if="$fetchState.pending">
         Loading
    </div>
    <div v-else-if="$fetchState.error">
        An error occurred :(
    </div>
    <main 
        id="data-area"
    >
        <section
            v-for="cat in categories"
            :id="cat"
            :key="cat"
            aria-labelledby="primary-heading"
            class="flex flex-col flex-1"
        >
            <div 
                v-if="$fetchState.pending === false && company[cat].public === true"
                :class="company === {} ? 'hidden' : 'block'"
            >
                <div id="section-header">
                    <h2>
                        {{ cat }}
                    </h2>
                    <p v-if="formattedDate(cat) !== null">
                        Updated:
                        {{ formattedDate(cat) }}
                    </p>
                </div>

                <CompanySports
                    v-if="cat === 'sports'"
                    class="pb-20 sm:pt-8"
                    :financials="company.sports"
                />

                <CompanyFinance
                    v-if="cat === 'finance'"
                    class="pb-20 sm:pt-8"
                    :financials="company.finance"
                />

            </div>
        </section>

        <a
            v-if="$fetchState.pending === false"
            :class="company === {} ? 'hidden' : 'block'"
            :href="`https://${company.website}`"
            target="_blank"
            >Visit Website
           </a>
