vue中v-for图片src路径错误

一、问题概述

<img :src="data.src" class="nav-img">

1. html结构如下：

1.  
   <ul class="nav-list">
2.  
   <li v-for="data in navlist" :key="data.index">
3.  
   <div class="item">
4.  
   <!--{{ data.src }}-->
5.  
   <img :src="data.src" class="nav-img">
6.  
   <p class="nav-title">{{ data.title }}</p>
7.  
   <p class="nav-desc">{{ data.desc }}</p>
8.  
   </div>
9.  
   </li>
10.  
    </ul>

2. navlist数据如下：

图片存在 ../../assets/images/index/ 文件夹下

1.  
   navlist: [
2.  
   {'title': '鱼塘', 'desc': 'world', 'src': '../../assets/images/index/navlist01.png'},
3.  
   {'title': '鱼塘', 'desc': 'world', 'src': '../../assets/images/index/navlist01.png'},
4.  
   {'title': '社群', 'desc': 'world', 'src': '../../assets/images/index/navlist02.png'},
5.  
   {'title': '积分', 'desc': 'world', 'src': '../../assets/images/index/navlist03.png'},
6.  
   {'title': '活动', 'desc': 'world', 'src': '../../assets/images/index/navlist04.png'},
7.  
   {'title': '直播', 'desc': 'world', 'src': '../../assets/images/index/navlist05.png'},
8.  
   {'title': '资源', 'desc': 'world', 'src': '../../assets/images/index/navlist06.png'},
9.  
   {'title': '鱼友', 'desc': 'world', 'src': '../../assets/images/index/navlist07.png'},
10.  
    {'title': '鱼圈', 'desc': 'world', 'src': '../../assets/images/index/navlist08.png'},
11.  
    {'title': '会员', 'desc': 'world', 'src': '../../assets/images/index/navlist09.png'}
12.  
    ]

 3. 页面效果如下

图片无法显示

 

4. 浏览器中html解析如下

路径正确，但图片不显示

 

5. assets与static文件夹的区别

assets：在项目编译的过程中会被webpack处理解析为模块依赖，只支持相对路径的形式，如< img src=”./logo.png”>和background:url(./logo.png),”./logo.png”是相对资源路径，将有webpack解析为模块依赖 

static：在这个目录下文件不会被被webpack解析。他会直接被复制到最终的打包目录(默认是dist/static)下。必须使用绝对路径引用这些文件，这是通过config.js文件中的build.assetsPublic和build.assertsSubDirectory链接来确定的。任何放在static/中文件需要以绝对路径的形式引用：/static[filename] 
根据webpack的特性，总的来说就是static放不会变动的文件，asserts放可能会变动的文件

二、解决方案

1. 用require()处理src路径

{'title': '鱼塘', 'desc': 'world', 'src': require('../../assets/images/index/navlist01.png')}

1.  
   data () {
2.  
   return {
3.  
   navlist: [
4.  
   {'title': '鱼塘', 'desc': 'world', 'src': require('../../assets/images/index/navlist01.png')},
5.  
   {'title': '鱼塘', 'desc': 'world', 'src': require('../../assets/images/index/navlist01.png')},
6.  
   {'title': '社群', 'desc': 'world', 'src': require('../../assets/images/index/navlist02.png')},
7.  
   {'title': '积分', 'desc': 'world', 'src': require('../../assets/images/index/navlist03.png')},
8.  
   {'title': '活动', 'desc': 'world', 'src': require('../../assets/images/index/navlist04.png')},
9.  
   {'title': '直播', 'desc': 'world', 'src': require('../../assets/images/index/navlist05.png')},
10.  
    {'title': '资源', 'desc': 'world', 'src': require('../../assets/images/index/navlist06.png')},
11.  
    {'title': '鱼友', 'desc': 'world', 'src': require('../../assets/images/index/navlist07.png')},
12.  
    {'title': '鱼圈', 'desc': 'world', 'src': require('../../assets/images/index/navlist08.png')},
13.  
    {'title': '会员', 'desc': 'world', 'src': require('../../assets/images/index/navlist09.png')}
14.  
    ]
15.  
    }
16.  
    }

2. html结构不变

1.  
   <ul class="nav-list">
2.  
   <li v-for="data in navlist" :key="data.index">
3.  
   <div class="item">
4.  
   <!--{{ data.src }}-->
5.  
   <img :src="data.src" class="nav-img">
6.  
   <p class="nav-title">{{ data.title }}</p>
7.  
   <p class="nav-desc">{{ data.desc }}</p>
8.  
   </div>
9.  
   </li>
10.  
    </ul>

3. 页面效果如下

正常显示

 

4. 浏览器中html解析如下

webpack打包之后src路径
