项目第一天底部导航组件（自己写）

1.页面结构

div.nav-footer>div.nav-footer-item*4>span.iconfont+span{xxx}

2.样式

.nav-footer {
  font-size: 16px;
  display: flex;
  position: fixed;
  bottom: 0;
  height: 50px;
  width: 100%;
  border-top: 1px solid #e7e7e7;
  background-color: #fff;
  .nav-footer-item {
    position: relative;
    display: flex;
    flex-direction: column;
    align-items: center;
    justify-content: center;
    width: 25%;
    .badge {
      position: absolute;
      top: 3%;
      left: 50%;
      width: 14px;
      height: 14px;
      border-radius: 7px;
      background-color: #e4393c;
      text-align: center;
      line-height: 14px;
      color: white;
      font-size: 12px;
    }
  }
}
.active {
  color: #26a2ff;
}

3.给底部导航里各个div或者li绑定双向数据和排他

:class="path==='/home' ? 'active' : ''"

4.定义path并获取

 return {
      path: this.$route.path
    }

5.给导航绑定一个点击事件

@cllick='jumpTo('home')'

6.定义函数记得传值name

 methods: {
    jumpTo (name) {
      this.$router.push({name: name})
    }
  }

7.组件写完了记得在需要用到的组件页面中使用它，还有记得挖坑

import TabBar from '@/components/tab-bar'
export default {
  components: {
    TabBar
  }
}
