react

import imgURL from './../images/photo.png';
<img src={imgURL } />

<img src={require('./../images/photo.png')} />

React src里面引入图片的几种方式es6不支持在<img />标签内直接写图片的路径，即<img src="../images/photo.png”/>

以下是错误的

正确引入方法

vue

import imgURL from './../images/photo.png';
<img :src="imgURL" />

<img :src="require('./../images/photo.png')" />

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

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>
