vue导航栏制作

1，在components新建commnn目录，然后再新建nav目录，在此目录下新建nav-bottom.vue文件和nav-item.vue文件

2，nav-bottom.vue中的内容：

　　　　

 <template>
   <div>
     <div class="nav">
       <slot></slot>   //插槽
     </div>
   </div>
 </template>

 <script>
   export default {
     name: "nav-bottom"
   }
 </script>

 <style scoped>
   .nav {
     display: flex;
     position: fixed;
     bottom: 0;
     left: 0;
     right: 0;
     background-color: #7b7b7b;
     height: 49px;
     text-align: center;
   }
 </style>

3，Nav-item代码：

　　

<template>
  <div class="nav-item" :class="{isactive:isactive}">
    <div @click="change">
      <slot name="font-image"></slot>  <--!显示字体图片-->
      <slot name="font"></slot>    <--!显示文字-->
    </div>
  </div>
</template>

<script>
  export default {
    name: "nav-item",
    props: {
      path :String  // 传递路径
    },
    computed: {
      isactive () {
        return this.$route.path.indexOf(this.path) !== -1
      }
    },
    methods: {
      change () {
        if (this.isactive===false) {
          this.$router.push(this.path)
        }

      }
    }
  }
</script>

<style scoped>
  .nav-item {
    flex: 1;
  }
  .isactive {
    color: red;
  }
</style>

4，设置导航下的每个字路由页面：

　　shopping  此目录下创建对应的vue文件

　　profile   此目录下创建对应的vue文件

　　homepage  此目录下创建对应的vue文件
　　classify   此目录下创建对应的vue文件

5，设置路由：

import Router from 'vue-router'
import Vue from 'vue'

const home = () => import('../components/homepage/Home_msg')
const classify = () => import('../components/classify/Classify')
const shopping = () => import('../components/shopping/Shopping')
const profile = () => import('../components/profile/Profile')

Vue.use(Router)
const routes = [
  {
    path: '',
    redirect: '/home'
  },
  {
    path:'/profile',
    component: profile
  },
  {
    path:'/classify',
    component: classify
  },
  {
    path:'/shopping',
    component: shopping
  },
  {
    path:'/home',
    component: home
  }
]
const router = new Router({
  routes,
  mode: 'history'
});
export default router

6，抽离组件新建navgation.vue:

 <template>
   <div class="aaa">
      <nav-item path="home" colorstyle="blue">
         <span class="iconfont" slot="font-image"></span>
         <div slot="font">首页</div>
      </nav-item>

       <nav-item path="classify" colorstyle="green">
          <span class="iconfont" slot="font-image"></span>
         <div slot="font">分类</div>
       </nav-item>

       <nav-item path="shopping" colorstyle="hotpink">
         <span class="iconfont" slot="font-image"></span>
         <div slot="font">购物车</div>
       </nav-item>

       <nav-item path="profile">
         <span class="iconfont" slot="font-image"></span>
          <div slot="font">我的</div>
       </nav-item>
   </div>
 </template>

 <script>
   import navItem from "./nav-item"
   export default {
     name: "navgative",
     components: {
       navItem
     }
   }
 </script>

 <style scoped>
      @import "../assets/images/style.css";

      @font-face {font-family: 'iconfont';
     src: url('../assets/images/fonts/icomoon.eot');
     src: url('../assets/images/fonts/icomoon.eot?#iefix') format('embedded-opentype'),
     url('../assets/images/fonts/icomoon.woff') format('woff'),
     url('../assets/images/fonts/icomoon.ttf') format('truetype'),
     url('../assets/images/fonts/icomoon.svg#iconfont') format('svg');
 }
 .iconfont{
     font-family:"iconfont" !important;
     font-size:16px;font-style:normal;
     -webkit-font-smoothing: antialiased;
     -webkit-text-stroke-width: 0.2px;
     -moz-osx-font-smoothing: grayscale;
     /*vertical-align: middle;*/
 }
   .aaa {
     display: flex;
     position: fixed;
     bottom: 0;
     left: 0;
     right: 0;
   }
 </style>

navgation.vue

7，app.vue引入组件：

　　

<template>
  <div id="app">
    <router-view></router-view>
    <navBottom>
        <navgative></navgative>
    </navBottom>
  </div>
</template>

<script>
  import navBottom from './components/nav-bottom'
  import navgative from './components/navgative'
export default {
  name: 'app',
  components: {
    navBottom,
    navgative
  }
}
</script>

<style>

</style>

app.vue

8，npm run serve 运行
