如何让vue-loader插值资产网址? [英] How can I get vue-loader to interpolate asset urls?

问题描述

我有一幅具有动态(内插)src属性的图像.

I have an image with a dynamic (interpolated) src attribute.

<img src="./{{bar}}.jpg"/>

<img src="./{{bar}}.jpg"/>

如何让vue-loader插值{{bar}}?

How do I get vue-loader to interpolate {{bar}}?

推荐答案

我很确定您的代码会引发警告(未引用):

I'm pretty sure that your code throws a warning (not referred it):

[Vue警告]:src ="./{{bar}}.jpg":在"src"属性中进行插值将导致404请求.改用v-bind:src.

[Vue warn]: src="./{{bar}}.jpg": interpolation in "src" attribute will cause a 404 request. Use v-bind:src instead.

因此，您应该绑定值:

<img :src="'/assets/' + bar + '.jpg'">

上面的示例从静态目录assets加载图像xxx.jpg，但尚未通过加载器加载.

The above example it loads an image xxx.jpg from the static directory assets, but not via loader yet.

要实现此目的，您应该使用动态需求:

To accomplish that, you should use a dynamic require:

<img :src="loadImage(name)">

methods: {
  loadImage (imgName) {
    return require('./assets/' + imgName + '.jpg')
  }
}

注意

不建议目录中包含大量文件，因为Webpack将加载与您的请求匹配的所有文件(对于上例:./assets/*.jpg).

It is not recommended if the directory contains a large number of files, because the webpack will be load all the files which match your request (for the above example: ./assets/*.jpg).
