【vue3.0】6.0 某东到家（六）——vue精简代码、css约束、vue工具使用

src\views\home\Docker.vue

<template>
  <!-- 底部主菜单容器 -->
  <div class="docker">
    <span
      :class="['docker__item', item.active]"
      v-for="(item, index) in dockerList"
      :key="index"
    >
      <div class="docker__item_icon">
        <i :class="item.icon"></i>
      </div>
      <div class="docker__item__title">{{ item.title }}</div>
    </span>
  </div>
</template>

<script>
export default {
  name: 'Docker',
  setup () {
    const dockerList = [
      {
        active: 'docker__item--active',
        icon: 'custom-icon custom-icon-home',
        title: '首页'
      },
      {
        icon: 'custom-icon custom-icon-shopping',
        title: '购物车'
      },
      {
        icon: 'custom-icon custom-icon-order',
        title: '订单'
      },
      {
        icon: 'custom-icon custom-icon-my',
        title: '我的'
      }
    ]

    return { dockerList }
  }
}
</script>

<style lang="scss" scoped>
@import '@/style/viriables';
@import '@/style/mixins';
.docker {
  color: $content-font-color;
  display: flex; //自适应均赠,弹性盒子
  position: absolute; //绝对定位
  box-sizing: border-box; //这个会以body的最外层作为容器的最外层
  padding: 0 0.18rem;
  left: 0;
  bottom: 0;
  width: 100%;
  height: 0.49rem;
  border-top: 1px solid $content-bg-color;
  &__item {
    flex: 1;
    text-align: center;
    &--active {
      color: #1fa4fc;
    }
    &_icon {
      margin: 0.05rem 0 0.02rem 0; //图标距离上边距7px左右;
      font-size: 0.18rem;
    }
    &__title {
      //浏览器最小像素是12px，如果想表达12px以下大小得如下编写
      font-size: 0.12rem;
      transform: scale(0.5 0.5); //横向缩小50% 纵向搜小50%
      transform-origin: center top; //缩放的中心点
    }
  }
}
</style>

更好的可以如下写：

<template>
  <!-- 底部主菜单容器 -->
  <div class="docker">
    <span
      :class="{ docker__item: true, 'docker__item--active': item.active }"
      v-for="(item, index) in dockerList"
      :key="index"
    >
      <div class="docker__item_icon">
        <i :class="item.icon"></i>
      </div>
      <div class="docker__item__title">{{ item.title }}</div>
    </span>
  </div>
</template>

<script>
export default {
  name: 'Docker',
  setup () {
    const dockerList = [
      {
        active: true,
        icon: 'custom-icon custom-icon-home',
        title: '首页'
      },
      {
        icon: 'custom-icon custom-icon-shopping',
        title: '购物车'
      },
      {
        icon: 'custom-icon custom-icon-order',
        title: '订单'
      },
      {
        icon: 'custom-icon custom-icon-my',
        title: '我的'
      }
    ]

    return { dockerList }
  }
}
</script>

scoped

只对当前组件有效

name

export default {
  name: 'Docker',

就是上面的name，可以不写，为什么写，是因为用于vue调试工具（Vue.js devtools）
如果不写，调试工具会显示文件的名字。
