vue+element ui 走馬燈添加圖片+圖片自適應

上面是最終效果圖~
代碼 (zmd.vue) ：

<template>
  <el-carousel :interval="4000" type="card" height="200px">
      <el-carousel-item v-for="item in imagebox" :key="item.id">
        <img :src="item.idView" class="image">
      </el-carousel-item>
    </el-carousel>
</template>

<script>
  export default{
    name:'zmd',
    data(){
      return {
        imagebox:[{id:0,idView:require('../assets/imagebox/1.jpg')},
        {id:1,idView:require('../assets/imagebox/2.jpg')},
        {id:2,idView:require('../assets/imagebox/3.jpg')}
        //imagebox是assets下一個放圖片的文件夾
        ]
      }
    }
  }
</script>

<style>
   .el-carousel__item h3 {
      color: #475669;
      font-size: 14px;
      opacity: 0.75;
      line-height: 200px;
      margin: 0;
    }

    .el-carousel__item:nth-child(2n) {
      background-color: #99a9bf;
    }

    .el-carousel__item:nth-child(2n+1) {
      background-color: #d3dce6;
    }
</style>

別忘了在APP.vue添加import

<script>
  import Zmd from './components/zmd.vue'
export default {
  name: 'App',
   components:{
    Zmd
  }
}
</script>

保存刷新我們發現圖片的比例似乎和框架不太匹配，這樣每次都要調節圖片大小，很麻煩。接下來我們來調節使圖片自適應。

<template>
  <!--動態將圖片輪播圖的容器高度設置成與圖片一致-->
  <el-carousel :interval="4000" type="card" height="zmdHeight + 'px'">
      <el-carousel-item v-for="item in imagebox" :key="item.id">
        <img :src="item.idView" class="image">
      </el-carousel-item>
    </el-carousel>
</template>

<script>
  export default{
    name:'zmd',
    data(){
      return {
        imagebox:[{id:0,idView:require('../assets/imagebox/1.jpg')},
        {id:1,idView:require('../assets/imagebox/2.jpg')},
        {id:2,idView:require('../assets/imagebox/3.jpg')}
        ],
         // 圖片父容器高度
        zmdHeight :700,
        // 瀏覽器寬度
        screenWidth :0
      }
    },
     methods:{
              setSize:function () {
                // 通過瀏覽器寬度(圖片寬度)計算高度
                this.bannerHeight = 400 / 1920 * this.screenWidth;
              },
            },
          mounted() {
              // 首次加載時,需要調用一次
              this.screenWidth =  window.innerWidth;
              this.setSize();
              // 窗口大小發生改變時,調用一次
              window.onresize = () =>{
              this.screenWidth =  window.innerWidth;
              this.setSize();
            }
          }
  }
</script>

<style>
   .el-carousel__item h3 {
      color: #475669;
      font-size: 14px;
      opacity: 0.75;
      line-height: 200px;
      margin: 0;
    }

    .el-carousel__item:nth-child(2n) {
      background-color: #99a9bf;
    }

    .el-carousel__item:nth-child(2n+1) {
      background-color: #d3dce6;
    }
    img{
     /*設置圖片寬度和瀏覽器寬度一致*/
      width:100%;
      height:inherit;
    }
</style>

這樣保存刷新之後圖片就很好看了！
