<mt-radio
  v-model="duration"
  :options= options
  align="right">
</mt-radio>

align="right"表示单选在文字的右边,有left和right两个属性

获取单选的value值和label值:

watch:{  
duration(newval,oldval){
  for(var i=0;i<this.options.length;i++){
    if(newval==this.options[i].value){
      console.log(this.options[i].label)
      this.bindduration = this.options[i].label;
    }
  }
}
