Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

1.介绍

这是一个基于element-ui二次封装的一个侧边菜单栏组件,能快捷的根据数据,生成响应的子菜单,并且解决路径被激活的时候,菜单不激活的问题

2.安装

npm i wf-sub-menu -S
yarn add wf-sub-menu

3. 使用

1.定义数据源

首先需要有一组数据,基于权限生成的用户菜单路由配置数据,这些数据应该是这样的

const routes = [
  {
    path: 'Welcome',
    name: 'Welcome',
    component: Welcome,
    meta: {
      name: '管理首页',
      icon: 'iconfont icon-shouye'
    }
  },
  {
    path: 'StudentManager',
    name: 'StudentManager',
    redirect:"/StudentManager/studentProduct",
    component: StudentManager,
    meta: {
      name: '学员管理',
      icon: 'iconfont icon-xueyuan'
    },
    children: [
      {
        path: 'studentProduct',
        name: 'studentProduct',
        component: studentProduct,
        meta: {
          name: '学员项目管理',
          icon: 'iconfont icon-wode1'
        }
      },
      {
        path: 'studentProfile',
        name: 'studentProfile',
        component: studentProfile,
        meta: {
          name: '学员资料',
          icon: 'iconfont icon-kaoqin2'
        }
      },
      {
        path: 'studentDormitory',
        name: 'studentDormitory',
        component: studentDormitory,
        meta: {
          name: '学员宿舍',
          icon: 'iconfont icon-shuju2'
        }
      }
    ]
  }
]

const router = new VueRouter({
  routes
})

export default router

如上所示,meta属性中,name属性最后会生成菜单名字,如果具有children属性,那么会对应生成子菜单,icon属性就是存放的菜单的图标类名(前提先安装字体图标)

2.修改main.js

引入wf-sub-menu组件,因为我们的组件基于element-ui二次封装,所以,我们要先配置element-ui

element-ui

安装element-ui

yarn add element-ui
import Vue from "vue"
import App from "./App"
// 引入element-ui
import ElementUI from 'element-ui'
import 'element-ui/lib/theme-chalk/index.css'
import subMenu from "wf-sub-menu" //引入我们的组件
Vue.use(ElementUI)
//使用Vue.use()将组件注入到所有的子组件
Vue.use(subMenu)

new Vue({
	h=>h(App)
}).$mount('#app')

3.嵌套在 element组件中的el-menu

像正常组件一样使用 ,并且需要注入数据源 属性名必须是 sideMenu(就是3-1所描述的数据源) 代码示例如下:

<el-menu :default-active="$route.path"
                 class="el-menu-vertical-demo"
                 text-color="#4e5bf8"
                 ref="sideMenu"
                 active-text-color="#E47833"
                 :collapse="isCollapse">
    	//我们的组件
          <sub-menu :sideMenu='sideMenu'></sub-menu>
        </el-menu>

4.启用菜单激活样式

务必配合路由使用

直接在el-menu组件上加上属性 :default-active="$route.path"

//:default-active="$route.path"


 <el-menu :default-active="$route.path" //加上此属性
                 class="el-menu-vertical-demo"
                 text-color="#4e5bf8"
                 ref="sideMenu"
                 active-text-color="#E47833"
                 :collapse="isCollapse">
          <!-- <subMenu :sideMenu='sideMenu'></subMenu> -->
          <sub-menu :sideMenu='sideMenu'></sub-menu>
        </el-menu>
