圖標(biāo)不見(jiàn)了

解決辦法是
把el-icon 從#title 中提取出來(lái)
如

    <el-menu-item
      v-if="hasChild(item) == 0"
      :index="resolvePath(item.path)"
      :key="resolvePath(item.path)"
    >
      <el-icon>
        <component :is="item.meta?.icon" />
      </el-icon>
      <template #title>
        <span>{{ item.meta?.title }}</span>
      </template>
    </el-menu-item>

運(yùn)行結(jié)果

el-icon 還是要放于#title里，否則顯示不正常文章來(lái)源地址http://www.zghlxwxcb.cn/news/detail-605794.html

<el-sub-menu
      v-if="hasChild(item) > 1"
      :index="resolvePath(item.path)"
      :key="resolvePath(item.path)"
    >
      <template #title>
        <el-icon v-if="item.meta?.icon">
          <component :is="item.meta?.icon" />
        </el-icon>
        <span>{{ item.meta?.title }}</span>
      </template>
