Vue JS 数据绑定不适用于 img src [英] Vue JS data binding not working for img src

问题描述

我正在使用 vue 2 和 vue-cli 3.我试图将标签的 src 绑定到数据中的变量.

具体来说，我正在执行以下操作:

<img class="img-time-matters" :src="`./../assets/time-comparison-${locale}.png`">导出默认{名称:家"，组件: {}，数据() {返回 {语言环境:语言环境//'en'};}}

绑定有效

使用 Chrome 开发者工具并检查网络活动，我发现绑定有效:

如何让 Vue 以正确解析绑定的方式进行数据绑定(即 time-comparison-en.74a6f0ca.png).

谢谢！

解决方案

请试试require

<img class="img-time-matters" :src="require(`../assets/time-comparison-${locale}.png`)">

I am using vue 2 and vue-cli 3. I am trying to bind the src of an tag to a variable in data.

Specifically I am doing the following:

<img class="img-time-matters" :src="`./../assets/time-comparison-${locale}.png`">

export default {
   name: "home",
   components: {},  
   data() {
       return {
           locale: locale // 'en'
       };
   }
}

The binding works

Using Chrome developer tools and examining the network activity I see that the binding works:

http://localhost:8080/assets/time-comparison-en.png

However the resource is not found.

If I remove data binding at hard code the course path to:

<img class="img-time-matters" :src="`./../assets/time-comparison-en.png`">

Vue resolves the resource link to look for the image at:

http://localhost:8080/img/time-comparison-en.74a6f0ca.png

How do I get the Vue to data bind in such a way that it resolves the binding correctly (i.e. time-comparison-en.74a6f0ca.png).

Thanks!

解决方案

Please try require

<img class="img-time-matters" :src="require(`../assets/time-comparison-${locale}.png`)">
