Vue用v-for给循环标签自身属性添加属性值的方法

<RadioGroup v-model="animal">
 <Radio v-for='a in radio_arr' label={{a}}></Radio>
</RadioGroup>
export default {
 data(){
 return{
  radio_arr:['循环1','循环2','循环3'],
    animal:'循环2'
 }
 }
} 

<RadioGroup v-model="animal">
 <Radio v-for='a in radio_arr' :label='a'></Radio>
</RadioGroup>
export default {
 data(){
  return{
   radio_arr:['循环1','循环2','循环3'],
   animal:'循环2',
  }
 }
}

<img v-for='url in imgurl' :src='url' />
export default {
 data(){
  return{
      imgurl:['../assets/img/icon1.png' ,
           '../assets/img/icon2.png']  
     }
  }
}

 imgurl:['../assets/img/icon1.png' , '../assets/img/icon2.png']

imgurl:[require('../assets/img/icon1.png') ,require('../assets/img/icon2.png')]

<img v-for='url in imgurl' :src='url' />
export default {
 data(){
  return{
   imgurl:[require('../assets/img/icon1.png') 
         ,require('../assets/img/icon2.png')]
  }
 }
}

/*错误写法*/
imgUrl:'../assets/logo.png'

<img :src="avatar" />
import avatar from '@/assets/logo.png'

imgUrl ： '../../static/logo.png'
<img :src="imgUrl" />
