跟我一起做一个vue的小项目（十一）

接下来我们进行的是详情页动态路由及banner布局
先看页面的效果

下面是代码部分

<template>
    <div>
      <div class="banner">
          <img src="//img1.qunarzz.com/sight/p0/1409/19/adca619faaab0898245dc4ec482b5722.jpg_600x330_f922b488.jpg" alt="" class="banner-img">
          <div class="banner-info">
            <div class="banner-title">
              故宫(AAAAA景区)
            </div>
            <div class="banner-number">
              <span class="iconfont">&#xe758;</span>
              39
            </div>
        </div>
      </div>
    </div>
</template>
<script>
export default {
  name: 'DetailBanner'
}
</script>
<style lang="stylus" scoped>
.banner
  overflow:hidden
  height:0
  padding-bottom:55%
  position:relative
  .banner-img{
    width:100%
  }
  .banner-info
    display:flex
    position:absolute
    left:0
    right:0
    bottom:0
    line-height:0.6rem
    background-image:linear-gradient(top,rgba(0,0,0,0),rgba(0,0,0,0.8))
    color:#fff
    .banner-title
      flex:1
      font-size:.32rem
      padding:0 .2rem
    .banner-number
      padding:0 .4rem
      height:.32rem
      line-height:.4rem
      margin-top:.24rem
      border-radius:.2rem
      background:rgba(0,0,0,.8)
      font-size:0.24rem
      .iconfont
        font-size:.24rem

</style>

接下来我们进行画廊组件的封装
首先修改webpack.base.conf.js文件

接下来我们进行gallery组件的封装
点击我们的banner图，会进入gallery组件里面，点击gallery里面的图片，关闭gallery图片，回到banner页面
我们可以先看效果

接下来我们来看代码
记住我们是将gallery封装成了一个公共组件，放在新建的common文件夹中

//gallery.vue
<template>
<div>
    <div class="container">
        <div class="wrapper" @click="handleGalleryClick">
            <swiper :options="swiperOptions">
    <!-- slides -->
    <!-- v-for="item of list" :key="item.id" -->
                <swiper-slide v-for="(item,index) in imgs " :key="index">
                    <img class="gallary-img" :src="item">
                </swiper-slide>
                <div class="swiper-pagination"  ></div>
            </swiper>
        </div>
    </div>
</div>
</template>
<script>
export default {
  name: 'commonGallary',
  props: {
    imgs: {
      type: Array
    //   default () {父组件不传值的时候
    //     return ['http://img1.qunarzz.com/sight/p55/201211/04/fbcab3e5d6479ce893835fbb.jpg_r_800x800_6360f514.jpg',
    //       'http://img1.qunarzz.com/wugc/p180/201306/16/7f08e81624346b1693835fbb.jpg_r_800x800_5f03ad73.jpg'
    //     ]
    //   }
    }
  },
  data () {
    return {
      swiperOptions: {
        pagination: '.swiper-pagination',
        paginationType: 'fraction',
        observeParents: true,
        observer: true

      }
    }
  },
  methods: {
    handleGalleryClick () {
      this.$emit('close')
    }
  }
}
</script>
<style lang="stylus" scoped>
.container >>> .swiper-container
    overflow:inherit
.container
    display:flex
    flex-direction:column
    justify-content:center
    overflow:hidden
    z-index:99
    position:fixed
    left:0
    right:0
    top:0
    bottom:0
    background:#000
    .wrapper
        width:100%
        height:0
        padding-bottom:100%
        .gallary-img
            width:100%
        .swiper-pagination
            color:#fff
            bottom:-1rem

</style>

我们在banner中引用gallery组件

//banner
<template>
    <div>
      <div class="banner" @click="handleBannerClick">
          <img src="//img1.qunarzz.com/sight/p0/1409/19/adca619faaab0898245dc4ec482b5722.jpg_600x330_f922b488.jpg" alt="" class="banner-img">
          <div class="banner-info">
            <div class="banner-title">
              故宫(AAAAA景区)
            </div>
            <div class="banner-number">
              <span class="iconfont">&#xe758;</span>
              39
            </div>
        </div>
      </div>
      <common-gallary
        :imgs="imgs"
        v-show="showGallery"
        @close="handlegalleryClose"
      ></common-gallary>
    </div>
</template>
<script>
import CommonGallary from 'common/gallary/Gallary'
export default {
  name: 'DetailBanner',
  data () {
    return {
      showGallery: false,
      imgs: [
        'http://img1.qunarzz.com/sight/p55/201211/04/fbcab3e5d6479ce893835fbb.jpg_r_800x800_6360f514.jpg',
        'http://img1.qunarzz.com/wugc/p180/201306/16/7f08e81624346b1693835fbb.jpg_r_800x800_5f03ad73.jpg'
      ]
    }
  },
  components: {
    CommonGallary
  },
  methods: {
    handleBannerClick () {
      this.showGallery = true
    },
    handlegalleryClose () {
      this.showGallery = false
    }
  }
}
</script>
<style lang="stylus" scoped>
.banner
  overflow:hidden
  height:0
  padding-bottom:55%
  position:relative
  .banner-img{
    width:100%
  }
  .banner-info
    display:flex
    position:absolute
    left:0
    right:0
    bottom:0
    line-height:0.6rem
    background-image:linear-gradient(top,rgba(0,0,0,0),rgba(0,0,0,0.8))
    color:#fff
    .banner-title
      flex:1
      font-size:.32rem
      padding:0 .2rem
    .banner-number
      padding:0 .4rem
      height:.32rem
      line-height:.4rem
      margin-top:.24rem
      border-radius:.2rem
      background:rgba(0,0,0,.8)
      font-size:0.24rem
      .iconfont
        font-size:.24rem

</style>
