基於角色本地存儲的側邊欄

Question

我找到了一個基於登錄角色隱藏一些側邊欄菜單的解決方案，我有 3 個角色，1 個用於管理員，2 個用於助手，3 個用於驅動程序模板代碼

`

<div class="sidebar px-0">
  <div class="user-panel mt-3 pb-3 mb-3 d-flex">
    <div class="image">
      <img
        src="../assets/images/user.jpg"
        class="img-circle elevation-2"
        alt="User Image"
      />
    </div>
    <div class="info">
      <a href="#" class="d-block">
        <b>{{ username }}</b>
      </a>
    </div>
  </div>

  <!-- List menu on sidebar -->
  <nav class="mt-2">
    <ul
      class="nav nav-sidebar flex-column"
      data-widget="treeview"
      data-accordion="false"
    >
      <li v-for="menu in menus" :key="menu.title" :class="menu.class">
        <router-link class="pl-3" :to="menu.link" :class="activeClass(menu.key)">
          <i style="font-size: .875rem;" :class="`nav-icon fa ${menu.icon} mr-2`"/>
          <p>
            {{ menu.title }}
            <i v-if="menu.submenus" class="right fa fa-angle-left"></i>
          </p>
        </router-link>
        <ul v-if="menu.submenus" class="nav nav-treeview">
          <li v-for="submenu in menu.submenus" :key="submenu.title" class="nav-item">
            <router-link class="pl-5" :to="submenu.link" :class="activeClass(submenu.key)">

              <p class="pl-2">{{ submenu.title }}</p>
            </router-link>
          </li>
        </ul>
      </li> 

    </ul>
  </nav>
</div>

我開始為聲明側邊欄菜單列表編寫腳本，在下面的代碼中我希望在部分算法側邊欄菜單中只顯示角色 2，但沒有任何反應

<script>

Answer 1

是的，可以根據角色隱藏菜單，但是您需要對代碼進行一些更改

在computed -> hasAuthority 代替profile.iid，你可以使用profile.roleId

hasAuthority() {
      return LocalStorage.getUser().profile.roleId
    },

同樣在模板子項中，添加一個 if 條件來檢查是否有權限 v-if="submenu.meta && submenu.meta.role == hasAuthority"

<ul v-if="menu.submenus" class="nav nav-treeview">
          <li v-for="submenu in menu.submenus" :key="submenu.title" class="nav-item" v-if="submenu.meta && submenu.meta.role == hasAuthority">
            <router-link class="pl-5" :to="submenu.link" :class="activeClass(submenu.key)">

              <p class="pl-2">{{ submenu.title }}</p>
            </router-link>
          </li>
        </ul>
