六、Vue项目去哪儿网 - 城市选择页列表布局、Better-scoll的使用及字母表布局

先上Better-scoll插件 gitHub地址： https://github.com/ustbhuangyi/better-scroll

码云创建city-search分支

输入命令行

git pull
git checkout city-list
npm run dev

City.vue中引入List.vue组件

List.vue写页面样式

<template>
  <div class="list">
    <div class="area">
      <div class="title border-topbottom">您的位置</div>
      <div class="button-list">
        <div class="button-wrapper">
          <div class="button">北京</div>
        </div>
      </div>
    </div>
    <div class="area">
      <div class="title border-topbottom">热门城市</div>
      <div class="button-list">
        <div class="button-wrapper">
          <div class="button">北京</div>
        </div>
        <div class="button-wrapper">
          <div class="button">北京</div>
        </div>
        <div class="button-wrapper">
          <div class="button">北京</div>
        </div>
        <div class="button-wrapper">
          <div class="button">北京</div>
        </div>
        <div class="button-wrapper">
          <div class="button">北京</div>
        </div>
      </div>
    </div>
    <div class="area">
      <div class="title border-topbottom">A</div>
      <div class="item-list">
        <div class="item border-bottom">阿拉尔</div>
        <div class="item border-bottom">阿拉尔</div>
        <div class="item border-bottom">阿拉尔</div>
        <div class="item border-bottom">阿拉尔</div>
      </div>
      <div class="title border-topbottom">B</div>
      <div class="item-list">
        <div class="item border-bottom">阿拉尔</div>
        <div class="item border-bottom">阿拉尔</div>
        <div class="item border-bottom">阿拉尔</div>
        <div class="item border-bottom">阿拉尔</div>
      </div>
      <div class="title border-topbottom">C</div>
      <div class="item-list">
        <div class="item border-bottom">阿拉尔</div>
        <div class="item border-bottom">阿拉尔</div>
        <div class="item border-bottom">阿拉尔</div>
        <div class="item border-bottom">阿拉尔</div>
      </div>
    </div>
  </div>
</template>

<script>
export default {
     
     
  name: 'CityList'
}
</script>

<style lang="scss" scoped>
@import '~styles/varibles.scss';
// 1像素边框问题
.border-topbottom {
     
     
  &::before {
     
     
    border-color: #ccc;
  }
  &::after {
     
     
    border-color: #ccc;
  }
}
.border-bottom {
     
     
  &::before {
     
     
    border-color: #ccc;
  }
}
.list {
     
     
  overflow: hidden;
  position: absolute;
  top: 1.58rem;
  left: 0;
  right: 0;
  bottom: 0;
  .title {
     
     
    padding: 0.1rem 0.2rem;
    line-height: 0.44rem;
    background: #eee;
  }
  .button-list {
     
     
    overflow: hidden;
    padding: 0.1rem 0.6rem 0.1rem 0.1rem;
    .button-wrapper {
     
     
      float: left;
      width: 33.33%;
      .button {
     
     
        margin: 0.1rem;
        padding: 0.14rem 0;
        text-align: center;
        border: 0.02rem solid #ccc;
        border-radius: 0.1rem;
      }
    }
  }
  .item-list {
     
     
    .item {
     
     
      line-height: 0.76rem;
      background: #fff;
      padding-left: 0.2rem;
    }
  }
}
</style>

使用Better-scoll使列表滚动

现在上下滑动是不行的，需要npm安装一下better-scroll这个插件来解决，然后重启下服务器。

npm i better-scroll
npm run dev

BetterScroll最常见的应用场景是列表滚动。让我们看看它的HTML布局:

如何使用：

List.vue

<template>
  <div class="list" ref="wrapper">
    <div>
      <div class="area">
        <div class="title border-topbottom">您的位置</div>
        <div class="button-list">
          <div class="button-wrapper">
            <div class="button">北京</div>
          </div>
        </div>
      </div>
      <div class="area">
        <div class="title border-topbottom">热门城市</div>
        <div class="button-list">
          <div class="button-wrapper">
            <div class="button">北京</div>
          </div>
          <div class="button-wrapper">
            <div class="button">北京</div>
          </div>
          <div class="button-wrapper">
            <div class="button">北京</div>
          </div>
          <div class="button-wrapper">
            <div class="button">北京</div>
          </div>
          <div class="button-wrapper">
            <div class="button">北京</div>
          </div>
        </div>
      </div>
      <div class="area">
        <div class="title border-topbottom">A</div>
        <div class="item-list">
          <div class="item border-bottom">阿拉尔</div>
          <div class="item border-bottom">阿拉尔</div>
          <div class="item border-bottom">阿拉尔</div>
          <div class="item border-bottom">阿拉尔</div>
        </div>
        <div class="title border-topbottom">B</div>
        <div class="item-list">
          <div class="item border-bottom">阿拉尔</div>
          <div class="item border-bottom">阿拉尔</div>
          <div class="item border-bottom">阿拉尔</div>
          <div class="item border-bottom">阿拉尔</div>
        </div>
        <div class="title border-topbottom">C</div>
        <div class="item-list">
          <div class="item border-bottom">阿拉尔</div>
          <div class="item border-bottom">阿拉尔</div>
          <div class="item border-bottom">阿拉尔</div>
          <div class="item border-bottom">阿拉尔</div>
        </div>
      </div>
    </div>
  </div>
</template>

<script>
import BScroll from 'better-scroll'
export default {
     
     
  name: 'CityList',
  // 在页面Dom挂载完毕后执行
  mounted () {
     
     
    this.scroll = new BScroll(this.$refs.wrapper)
  }
}
</script>

<style lang="scss" scoped>
@import '~styles/varibles.scss';
// 1像素边框问题
.border-topbottom {
     
     
  &::before {
     
     
    border-color: #ccc;
  }
  &::after {
     
     
    border-color: #ccc;
  }
}
.border-bottom {
     
     
  &::before {
     
     
    border-color: #ccc;
  }
}
.list {
     
     
  overflow: hidden;
  position: absolute;
  top: 1.58rem;
  left: 0;
  right: 0;
  bottom: 0;
  .title {
     
     
    padding: 0.1rem 0.2rem;
    line-height: 0.44rem;
    background: #eee;
  }
  .button-list {
     
     
    overflow: hidden;
    padding: 0.1rem 0.6rem 0.1rem 0.1rem;
    .button-wrapper {
     
     
      float: left;
      width: 33.33%;
      .button {
     
     
        margin: 0.1rem;
        padding: 0.14rem 0;
        text-align: center;
        border: 0.02rem solid #ccc;
        border-radius: 0.1rem;
      }
    }
  }
  .item-list {
     
     
    .item {
     
     
      line-height: 0.76rem;
      background: #fff;
      padding-left: 0.2rem;
    }
  }
}
</style>

字母表布局

创建Alphabet.vue组件

<template>
  <ul class="list">
    <li class="item">A</li>
    <li class="item">A</li>
    <li class="item">A</li>
    <li class="item">A</li>
    <li class="item">A</li>
    <li class="item">A</li>
    <li class="item">A</li>
    <li class="item">A</li>
    <li class="item">A</li>
    <li class="item">A</li>
    <li class="item">A</li>
    <li class="item">A</li>
  </ul>
</template>

<script>
export default {
     
     
  name: 'Alphabet'
}
</script>

<style lang="scss" scoped>
@import '~styles/varibles.scss';
.list {
     
     
  display: flex;
  flex-direction: column;
  justify-content: center;
  position: absolute;
  top: 1.58rem;
  right: 0;
  bottom: 0;
  width: 0.4rem;
  .item {
     
     
    text-align: center;
    line-height: 0.4rem;
    color: $bgColor;
  }
}
</style>

效果如下：
