通过引用组件实现做菜单栏

前端样式

使用了iview的布局组件

控制左菜单栏的前端主父组件代码

<template>
    <div id="Home">
        <Layout :style="{minHeight: '100vh'}" >
            <Sider collapsible :collapsed-width="78" v-model="isCollapsed">
                <Menu 
                    v-model="option"  
                    active-name="detail" 
                    theme="dark" 
                    width="auto" 
                    :class="menuitemClasses" 
                    @on-select="changeOption($event)">
                    <MenuItem v-for="(item,index) in menuList" :key="index" :name="item.name">
                        <Icon :type="item.icon"></Icon>
                        <span >{{item.detail}}</span>
                    </MenuItem>
                </Menu>
            </Sider>
            <Layout>
                <Card>
                    {{option}}
                    <cluster-info v-if="option=='detail'"></cluster-info>
                    <topic-apply v-if="option=='topicApply'"></topic-apply>
                    <change-white-list-apply v-if="option=='whitelist'"></change-white-list-apply>
                </Card>
            </Layout>
        </Layout>
    </div>
</template>

    import ClusterInfo from '../components/cluster/ClusterInfo'

    export default {

            return {
                isCollapsed: false,
                menuList: [
                    {
                    name: "detail",
                    detail: "集群概述",
                    icon: "ios-archive-outline"
                    },

                ],
                option:"detail",

        mounted(){
        },
        created(){
            // this.$nextTick(()=>{
            //     console.log('refs:')
            //     console.log(this.$refs.menu)
            // })
        },
        computed: {            
            menuitemClasses: function () {
                return [
                    'menu-item',
                    this.isCollapsed ? 'collapsed-menu' : ''
                ]
            }
        },
        components:{
            ClusterInfo,
            ChangeWhiteListApply,
            TopicApply
        },
        methods:{
            changeOption(e){
                this.option=e
                // console.log('=====')
                // console.log(this.option)
                // console.log(e)
            }
        }
    }
</script>

1. 通过import 导入组件

组件即为自定义的vue页面

2. 在vue实例中通过components注册组件

3. 组件名是驼峰命名的，直接在template标签内使用组件，如

组件名为：ClusterInfo

则使用方式为:<cluster_info></cluster_info>

4. Menu组件绑定数据option，通过option可以判断当前点击的是那个Menu，然后再使用对应的组件将页面渲染
