src dynamic assignment of img in vue (require method)

• If you don't want to change the path, you can use require to load the image as a module
• Using require is to import the picture as a module first, and then bind it.

<!--静态-->
<v-img :src="require('../../assets/img/classic.jpg')" alt="picture"/>
<!--动态-->
<v-img :src="require('@/assets/img/'+testUrl+'.png')"/>

• When you need to implement dynamic loading of pictures, you need to pass a variable to require, and assign a value to this variable in the method

<template>
    <v-card class="my-auto mx-0" flat tile>
       <v-img :src="require('@/assets/img/'+testUrl+'.png')"/>
    </v-card>
</template>

<script>

export default {
  name: "assessmentResults",
  data() {
    return {
      testUrl:"1img",//测评图片路径
    }
  },
  methods: {
    ingUrl(){
      //...
      this.testUrl="222img";
    },
  },
}

</script>
