【微人事项目笔记】3、Home页的title以及左边导航菜单的制作

1、Home页的title和左边导航菜单

上一小节完成了成功登录之后跳转到home页，这篇笔记主要记录home的title和坐标导航菜单的制作，参考 https://element.eleme.cn/#/zh-CN/component/dropdown 下来菜单，技术要点v-for循环，this.$router.push(index)的时候会先去Home组件看是否有<router-view></router-view>,这是因为在router.js里面对要展示的组件路由放在了Home组件的children属性里。
Home.vue:

<template>
    <div>
        <el-container class="homeContainer">
            <el-header class="homeHeader">
                <div class="title">微人事</div>
                <el-dropdown class="userInfo" @command="handleCommand">
                    <span class="el-dropdown-link">
                      {{user.name}}<i><img :src="user.userface" alt="用户头像"></i>
                    </span>
                    <el-dropdown-menu slot="dropdown">
                        <el-dropdown-item command="userinfo">个人中心</el-dropdown-item>
                        <el-dropdown-item command="setting">设置</el-dropdown-item>
                        <el-dropdown-item divided command="logout">注销登录</el-dropdown-item>
                    </el-dropdown-menu>
                </el-dropdown>
            </el-header>

            <el-container>
                <el-aside width="200px">
                    <el-menu @select="menuClick">
                        <!--                        循环加载router中的children-->
                        <el-submenu index="1" v-for="(item, index) in this.$router.options.routes" v-if="!item.hidden">
                            <template slot="title">
                                <i class="el-icon-location"></i>
                                <span>{{item.name}}</span>
                            </template>
                            <el-menu-item :index="child.path" v-for="(child, indexj) in item.children">{{child.name}}
                            </el-menu-item>
                        </el-submenu>
                    </el-menu>
                </el-aside>

                <el-main>
                    <router-view></router-view>
                </el-main>
            </el-container>
        </el-container>
    </div>
</template>

<script>
    export default {
        name: 'Home',
        data() {
            return {
                user: JSON.parse(window.sessionStorage.getItem('user'))
            }
        },
        methods: {
            menuClick(index, indexPath) {
                this.$router.push(index)
            },
            handleCommand(command) {
                if (command == 'logout') {
                    this.$confirm('此操作将注销登录, 是否继续?', '提示', {
                        confirmButtonText: '确定',
                        cancelButtonText: '取消',
                        type: 'warning'
                    }).then(() => {
                        this.getRequest('/logout')
                        window.sessionStorage.removeItem('user')
                        this.$router.replace('/')
                    }).catch(() => {
                        this.$message({
                            type: 'info',
                            message: '已取消操作'
                        });
                    });
                }
            }
        }
    }
</script>

<style>
    .homeHeader {
        background-color: #409eff;
        display: flex;
        align-items: center;
        justify-content: space-between;
        padding: 0px 15px;
        box-sizing: border-box;
    }

    .homeHeader .title {
        font-size: 30px;
        font-family: 华光行楷_CNKI;
        color: #ffffff;
    }

    .homeHeader .userInfo {
        cursor: pointer;
    }

    .el-dropdown-link img {
        width: 48px;
        height: 48px;
        border-radius: 24px;
        margin-left: 8px;
    }

    .el-dropdown-link {
        display: flex;
        align-items: center;
    }
</style>

2、router.js，把要展示的组件放在了Home组件的children里

import Vue from 'vue'
import Router from 'vue-router'
import Login from './views/Login.vue'
import Home from './views/Home.vue'
import Test1 from "./views/Test1";
import Test2 from "./views/Test2";

Vue.use(Router)

export default new Router({
    routes: [
        {
            path: '/',
            name: 'Login',
            component: Login,
            hidden: true
        },
        {
            path: '/home',
            name: 'Home',
            component: Home,
            hidden: true
        },
        {
            path: '/home',
            name: '导航一',
            component: Home,
            children: [
                {
                    path: '/test1',
                    name: '选项1',
                    component: Test1
                },
                {
                    path: '/test2',
                    name: '选项2',
                    component: Test2
                }
            ]
        }
    ]
})

3、测试

登录之后跳转home页，点击菜单选项，展示相关组件，
