链接到 Vue.js 中 vuex 存储中引用的图像 [英] Linking to images referenced in vuex store in Vue.js

问题描述

我是第一次使用 Vue.js 如果这是一个基本问题，我很抱歉 - 我已经使用 vue-cli、vue-router 和 vuex 如果此信息有帮助.

我在这里的主要问题是显示图像或访问资产.我能够通过getter"从数据存储中提取适当的数据/状态并在其中迭代数组等(例如，{{student.name}} 工作得很好)但是当我尝试使用 <img :src='student.image'> 显示图像，但它无法加载，并且我得到一个断开的链接图标.我做了一些研究，似乎有一个 webpack 命名约定用于将资产与 ~/ 或 ~@/ 链接，但是这些似乎都不起作用.

我见过其他示例，其中人们只是从组件链接到固定资产，但因为我正在迭代 students 数组，所以我需要一种更具编程性的方法.我看过一些使用 computed() 属性的例子，但我觉得这应该是不必要的?

以下是我的组件中的代码以及我的 store.js 文件的相关部分.

Store.js:

从'vue'导入Vue从 'vuex' 导入 VuexVue.use(Vuex)导出默认新 Vuex.Store({状态: {用户:{得分:0},学生们: [{编号:1，name: 'Advik',年龄:'19'，学习:物理治疗"，图像:'~/assets/images/students/advik-1.png'},{编号:2，name: '杰克',年龄:'19'，学习:戏剧"，图像:'~/assets/images/students/jake-1.png'},{编号:3，name: '梅尔',年龄:'20'，学习:土木工程"，图像:'~/assets/images/students/mel-1.png'},{编号:4，name: 'Kaya',年龄:'18'，学习:'法律'，图像:'~/assets/images/students/kaya-1.png'}]},突变:{},方法: {},吸气剂:{getStudents:状态 =>学生},动作:{}})

介绍组件:

 <模板><div><div class="m-background"></div><品牌/><div class="l-container"><div v-for="student in getStudents":key="student.id"><router-link class="m-btn m-btn--left m-btn__primary":to="{ name: 'home' }">{{ student.name }}</路由器链接>

<脚本>从 'vuex' 导入 { mapGetters }从../../components/Brand"导入品牌导出默认{成分: {牌},计算:{...mapGetters(['getStudents'])},名称:'介绍'}<风格></风格>

非常感谢！

解决方案

:src='student.image' (v-binding) 在运行时执行，但 webpack 别名在编译时工作.所以你必须在require中包装别名文件路径.

<代码>{编号:1，name: 'Advik',年龄:'19'，学习:物理治疗"，图像:需要('~@/assets/images/students/advik-1.png')}

I am using Vue.js for the first time so apologies if this is a basic question – I have set up the vue project with the vue-cli, vue-router and vuex if this information is helpful.

My main issue here is with displaying images or accessing assets. I am able to pull the appropriate data/state in from a data store via a 'getter' and iterate arrays, etc within it (for example, {{student.name}} works perfectly) however when I attempt to display an image with <img :src='student.image'> it fails to load and I get a broken link icon. I've done some research and it seems that there is a webpack naming convention for linking assets with ~/ or ~@/ however neither of these seem to work.

I've seen other examples where people simply link to a fixed asset from the component but because I am iterating the students array I need a more programmatic method. I've seen some examples using computed() properties but I feel like this should be unnecessary?

Below is the code from my component and the relevant parts of my store.js file.

Store.js:

import Vue from 'vue'
import Vuex from 'vuex'

Vue.use(Vuex)

export default new Vuex.Store({
  state: {
    user: {
      score: 0
    },
    students: [
      {
        id: 1,
        name: 'Advik',
        age: '19',
        studying: 'Physiotherapy',
        image: '~/assets/images/students/advik-1.png'
      },
      {
        id: 2,
        name: 'Jake',
        age: '19',
        studying: 'Drama',
        image: '~/assets/images/students/jake-1.png'
      },
      {
        id: 3,
        name: 'Mel',
        age: '20',
        studying: 'Civil Engineering',
        image: '~/assets/images/students/mel-1.png'
      },
      {
        id: 4,
        name: 'Kaya',
        age: '18',
        studying: 'Law',
        image: '~/assets/images/students/kaya-1.png'
      }
    ]
  },
  mutations: {

  },
  methods: {

  },
  getters: {
    getStudents: state => state.students
  },
  actions: {

  }
})

Intros component:

 <template>
  <div>
    <div class="m-background"></div>
    <Brand />
    <div class="l-container">
      <div v-for="student in getStudents"
           :key="student.id">
           <img :src='student.image'>
           <router-link class="m-btn m-btn--left m-btn__primary"
            :to="{ name: 'home' }">{{ student.name }}
           </router-link>
      </div>
    </div>
  </div>
</template>

<script>
import { mapGetters } from 'vuex'
import Brand from '../../components/Brand'

export default {
  components: {
    Brand
  },
  computed: {
    ...mapGetters(['getStudents'])
  },
  name: 'Intros'
}
</script>

<style>

</style>

Thank you so much!

解决方案

:src='student.image' (v-binding) is executed at runtime, but webpack aliases work in compile time. So you have to wrap the aliased file path in require.

{
  id: 1,
  name: 'Advik',
  age: '19',
  studying: 'Physiotherapy',
  image: require('~@/assets/images/students/advik-1.png')
}
