addressModel是父组件传来的字符串
option 是接口获取的数组 { address:'',id:* }
选完后会将报错‘Invalid prop: type check failed for prop "addressModel". Expected String with value "[object Object]", got Object ’

<el-select v-model="addressModel"
             @change="emitValue">
    <el-option v-for="item in option"
               :key="item.id"
               :label="item.full_address"
               :value="item">
    </el-option>
  </el-select>
