（二十四）VueCli3.0全栈——设置左侧导航栏

1、client/src/components下面新建LeftMenu.vue文件

<template>
  <el-row class="menu_page">
    <el-col>
      <el-menu
        class="el-menu-vertical-demo"
        background-color="#324057"
        text-color="#fff"
        active-text-color="#409eff"
      >
        <router-link to="/home">
          <el-menu-item index="0">
            <i class="fa fa-margin fa-server"></i>
            <span slot="title">首页</span>
          </el-menu-item>

          <template v-for="item in items">
            <el-submenu v-if="item.children" :index="item.path" :key="item.path">
              <template slot="title">
                <i :class="'fa fa-margin'+item.icon"></i>
                <span slot="title">{{item.name}}</span>
              </template>
              <router-link v-for="(citem,cindex) in item.children" :to="citem.path" :key="cindex">
                <el-menu-item :index="citem.path">
                  <span slot="title">{{citem.name}}</span>
                </el-menu-item>
              </router-link>
            </el-submenu>
          </template>
        </router-link>
      </el-menu>
    </el-col>
  </el-row>
</template>

<script>
export default {
  name: "left-menu",
  data() {
    return {
      items: [
        {
          icon: "fa-money",
          name: "资金管理",
          path: "fund",
          children: [{ path: "fundlist", name: "资金流水" }]
        },
        {
          icon: "fa-asterisk",
          name: "信息管理",
          path: "info",
          children: [{ path: "infoshow", name: "个人信息" }]
        }
      ]
    };
  }
};
</script>

<style scoped>
.menu_page{
    position: fixed;
    top: 71px;
    left: 0;
    min-height: 100%;
    background-color: #324057;
    z-index: 99;
}
.el-menu {
  border: none;
}
.fa-margin {
  margin-right: 5px;
}
.el-menu-vertical-demo:not(.el-menu--collapse) {
  width: 180px;
  min-height: 400px;
}

.el-menu-vertical-demo {
  width: 35px;
}
.el-submenu .el-menu-item {
  min-width: 180px;
}
.hiddenDropdown,
.hiddenDropname {
  display: none;
}
a {
  text-decoration: none;
}
</style>

2、client/src/views/Index.vue里面引入并使用

<template>
    <div class="index">
        <HeadNav></HeadNav>
        <LeftMenu></LeftMenu>
        <router-view></router-view>

    </div>
</template>

<script>
import HeadNav from '../components/HeadNav'
import LeftMenu from '../components/LeftMenu'
export default {
    name:'index',
    components: {
        HeadNav,
        LeftMenu
    }
}
</script>

<style>
.index{
    width: 100%;
    height: 100%;
    overflow: hidden;
}

</style>
