Eine kurze Analyse zum Umgang mit Ausnahmen in dynamischen Vue3-Komponenten

// 动态路由
export const asyncRouterMap: Array<RouteRecordRaw> = [
  {
    path: &#39;/&#39;,
    name: &#39;index&#39;,
    meta: { title: &#39;首页&#39; },
    component: BasicLayout, // 引用了 BasicLayout 组件
    redirect: &#39;/welcome&#39;,
    children: [
      {
        path: &#39;welcome&#39;,
        name: &#39;Welcome&#39;,
        meta: { title: &#39;引导页&#39; },
        component: () => import(&#39;@/views/welcome.vue&#39;)
      },
      ...
    ]
  }
]

    <el-tabs :model-value="copyTabName" type="card">
      <template v-for="item in tabList" :key="item.key || item.name">
        <el-tab-pane
          :name="item.key"
          :label="item.name"
          :disabled="item.disabled"
          :lazy="item.lazy || true"
        >
          <template #label>
            <span>
              <component v-if="item.icon" :is="item.icon" />
              {{ item.name }}
            </span>
          </template>
          // 关键在这里
          <component :key="item.key || item.name" :is="item.component" v-bind="item.props" />

import { markRaw, ref } from 'vue'

import A from './components/A.vue'
import B from './components/B.vue'

  name: string
  component: Component
  // ...

const tab = ref<ComponentList[]>([{
    name: "组件 A",
    component: markRaw(A)

import { markRaw } from 'vue'

// 动态路由
export const asyncRouterMap: Array<RouteRecordRaw> = [
  {
    path: &#39;/&#39;,
    name: &#39;home&#39;,
    meta: { title: &#39;首页&#39; },
    component: markRaw(BasicLayout), // 使用 markRaw
    // ...
  }
]

const state = shallowRef({ count: 1 })

// 不会触发更改
state.value.count = 2

// 会触发更改
state.value = { count: 2 }
