Vue实例:医院统一信息平台(构建项目)

前言

前面一段时间公司里忙得很晚，睡觉时间都不太够了，就隔了几天。服务端的用户系统已经完成。现在来一点前端的内容。我觉得前后端分离就可以各开发各的。相互之间用某种协议进行交互，整合。我的理解整个平台会由N个服务端项目、N个前端项目、加一些中间件构成。前端可能有WEB页面、手机APP、微信公众号页面、H5页面等等。
这里我们开始做PC端的后台管理页面。我把PC端分为前台、后台、登录三个项目。目前先这样，后续可能还会根据实际情况细分。几个项目都是Vue项目，就把它们合到一个工程中进行，省去共用模块、组件的重复管理。这个工程就需要多入口的Vue工程。

创建项目

因为我已经写过Vue多入口项目创建的文章，这里就不再重复了。移步vue多入口项目。项目名称huip。git地址:https://gitee.com/biboheart/huip-vue.git
创建完成后的目录结构：

目录结构

引入图标

在应用型前端中，图标会用的比较多。fontawesome图标库中的免费图标是比较丰富的。只是npm中最高版本到4.7.2就没有再更新。而官网已经到了5.1.0 。所以我选择下载到本地静态引入的方法使用5.1.0（哪位朋友有好的方法还忘告知）。
从官网下载，拷贝到static目录中。在index.html文件中引入css

<!DOCTYPE html>
<html>
  <head>
    <meta charset="utf-8">
    <meta name="viewport" content="width=device-width,initial-scale=1.0">
    <link href="static/fontawesome/css/fontawesome-all.min.css" rel="stylesheet">
    <title>huip</title>
  </head>
  <body>
    <div id="app"></div>
    <!-- built files will be auto injected -->
  </body>
</html>

引入前端框架

我采用element-ui作为vue前端框架。里面的组件比较丰富。包含了常用的管理组件了。

cnpm i element-ui -S

在三个main.js加入element-ui库，完成后的main.js内容如下

import Vue from 'vue'
import App from '@/components/App'
import router from './router'
import ElementUI from 'element-ui'
import 'element-ui/lib/theme-chalk/index.css'

Vue.config.productionTip = false
Vue.use(ElementUI)

/* eslint-disable no-new */
new Vue({
  el: '#app',
  router,
  components: { App },
  template: '<App/>'
})

界面布局

在这个工程中，各项目（除了登录）的布局都是基本相同的。因此，需要一个公共的布局组件。利用element的Container 布局容器进行开发。
element-ui的NavMenu 导航菜单，官方提供的每个菜单项是需要自己去生成的，并不能通过树型结构的数据生成出整个菜单。因此，我们先来写个组件，递归生成树型菜单。
以下是一个菜单项的组件代码。

<template>
  <component v-bind:is="currentItemComponent" :index="menu.path" :key="menu.path">
    <i :class="menu.icon" v-if="menu.icon && !hc"></i><span v-if="!hc">{{menu.text}}</span>
    <template slot="title" v-if="hc">
      <i :class="menu.icon" v-if="menu.icon"></i><span slot="title">{{menu.text}}</span>
    </template>
    <tree-menu-item :menu="child" :key="child.name" v-for="child in menu.children" v-if="hc && child.menu"></tree-menu-item>
  </component>
</template>

<script>
export default {
  name: 'TreeMenuItem',
  props: {
    menu: Object
  },
  data () {
    return {
      hc: false
    }
  },
  computed: {
    currentItemComponent: function () {
      return this.hasChildren() ? 'el-submenu' : 'el-menu-item'
    }
  },
  methods: {
    hasChildren () {
      this.hc = !!this.menu.hasChildren && this.menu.children && this.menu.children.length > 0
      return this.hc
    }
  }
}
</script>

<style scoped>
</style>

在公共布局组件中layout.vue中使用它：

<script>
import TreeMenuItem from '../packages/tree-menu/index.js'
export default {
  name: 'HuipLayout',
  components: {
    TreeMenuItem
  },
  props: {
    hmenus: Array,
    vmenus: Array,
    tips: Array,
    logoSrc: String,
    badgeValue: [String, Number]
  },
  data: function () {
    return {
      isCollapse: false,
      asideWidth: '230px',
      vDefActive: this.activePath(3),
      hDefActive: this.activePath(2),
      defaultLogo: require('@/assets/logo.png')
    }
  },
  watch: {
    '$route': function (val) {
      this.vDefActive = this.activePath(3)
      this.hDefActive = this.activePath(2)
    }
  },
  methods: {
    collapseChange: function () {
      this.isCollapse = !this.isCollapse
      this.$emit('changeCollapse', this.isCollapse)
      if (this.isCollapse) {
        this.asideWidth = '65px'
      } else {
        this.asideWidth = '230px'
      }
    },
    activePath: function (max) {
      let pathArr = this.$route.path.split('/')
      let def = ''
      if (max < 2) {
        def = this.$route.path
      } else {
        if (pathArr && pathArr.length > max) {
          for (let i = 1; i < max; i++) {
            def += '/' + pathArr[i]
          }
        } else {
          def = this.$route.path
        }
      }
      return def
    },
    clickLogo: function (...args) {
      this.$emit('logo-click', ...args)
    }
  }
}
</script>

完成布局

/src/project/index/pages下创建index.vue文件，这是前台页面的主体组件

后台(admin)中也同样创建一个主体页面组件。
这里的菜单数据是临时数据，为了看布局效果，最终是根据路由文件生成菜单的。
