elementui组件封装(el-menu)

废话不多说直接上代码：

递归菜单项：

<template>
  <el-submenu v-if="menuData.children && menuData.children.length > 0" :index="menuData.menuId">
    <template slot="title">
      <i class="el-icon-location" />
      <span>{{ menuData.menuDesc }}</span>
    </template>

    <MenuItem v-for="item in menuData.children" :key="item.menuId" :menu-data="item" />
  </el-submenu>

  <el-menu-item v-else :index="menuData.menuId">
    <i class="el-icon-menu" />
    <span slot="title">{{ menuData.menuDesc }}</span>
  </el-menu-item>
</template>

<script>
export default {
  name: 'MenuItem',
  // eslint-disable-next-line vue/require-prop-types
  props: ['menuData'],
  data() {
    return {
      // menuData: [{ menuId: '1', menuDesc: '导航1', parentMenu: null, children: [{ menuId: '1-1', menuDesc: '导航1-1', parentMenu: '1' }] }]
    }
  },
  methods: {
    handleOpen(key, keyPath) {
      console.log(key, keyPath)
    },
    handleClose(key, keyPath) {
      console.log(key, keyPath)
    }
  }
}
</script>

　　外层代码：

<el-menu default-active="1" mode="horizontal">
        <menu-item v-for="item in menuList" :key="item.id" :menu-data="item" />
      </el-menu>



// 数据示例：
menuList: [{ menuId: '1', menuDesc: '导航1', children: [{ menuId: '1-1', menuDesc: '导航1-1', children: null }] }, { menuId: '2', menuDesc: '导航2', children: [] }]
