[JavaScript知识库]vue2+element-ui实现侧边导航栏

创建LeftMenu.vue

编写client/src/components/LeftMenu.vue，创建侧边导航栏：

<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>
                </router-link>

                <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>
            </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>

配置Index.vue

编辑client/src/views/Index.vue，引入侧边导航栏：

<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>
