Vue引入img图片

时间:2022-05-22 Jesse90s 人气:0

我们在学习html的时候，图片标签<img>引入图片

<img src="../assets/images/avatar.png" width="100%">

但是这样会有2个弊端：

因为采用绝对路径引入，所以如果后面这张图片移动了目录，就需要修改代src里的路径
如果这张图片在同一页面内有多个地方要使用到，就需要引入多次，而且图片移动了目录，这么多地方都要修改src路径

怎么办？使用动态路径import、require

首先讲讲这两个兄弟，在ES6之前，JS一直没有自己的模块语法，为了解决这种尴尬就有了require.js，在ES6发布之后JS又引入了import的概念

使用import引入

import之后需要在data中注册一下，否则显示不了

<script>
import lf1 from '@/assets/images/cityOfVitality/lf1.png'
import lf2 from '@/assets/images/cityOfVitality/lf2.png'
import lf3 from '@/assets/images/cityOfVitality/lf3.png'
import lf4 from '@/assets/images/cityOfVitality/lf4.png'
import lf5 from '@/assets/images/cityOfVitality/lf5.png'
import lf6 from '@/assets/images/cityOfVitality/lf6.png'
import lf7 from '@/assets/images/cityOfVitality/lf7.png'
import top1 from '@/assets/images/cityOfVitality/icon_top1.png'
import mixins from './mixins'
export default {
  name: 'LeftPiece',
  mixins: [mixins],
  data () {
    return {
      lf1,
      lf2,
      lf3,
      lf4,
      lf5,
      lf6,
      lf7,
      top1
    }
  }
}
</script>

使用require引入

<script>
import top1 from '@/assets/images/cityOfVitality/icon_top1.png'
import mixins from './mixins'
export default {
  name: 'RightPiecr',
  mixins: [mixins],
  data () {
    return {
      rt1: require('@/assets/images/cityOfVitality/rt1.png'),
      rt2: require('@/assets/images/cityOfVitality/rt2.png'),
      rt3: require('@/assets/images/cityOfVitality/rt3.png'),
      rt4: require('@/assets/images/cityOfVitality/rt4.png'),
      rt5: require('@/assets/images/cityOfVitality/rt5.png'),
      rt6: require('@/assets/images/cityOfVitality/rt6.png'),
      top1
    }
  }
}
</script>
