 <Option v-for="item in dataArr" :key="item.code" :value="item.code" :label="item.codename" :disabled="item.disabled"></Option>
</Select>

methods: {
 selectInsurance(){ //刷新车辆保险可选状态
 for(var i=0; i<this.dataArr.length; i++){ 
  var flag = false; //默认没有选中
  var itemI = this.dataArr[i];
  for(var j=0; j<this.form.carInsuranceVOList.length; j++){ //检测选项是否已被选中过
  var itemJ = this.form.carInsuranceVOList[j];
  if(itemI.code == itemJ.insuranceName){
   flag = true;
   break;
  }
  }
  if(flag){
  itemI.disabled = true;
  }else{
  itemI.disabled = false;
  }
 }
