element-ui的select组件v-model是个字符串，而option的:value需要对象

Question

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>

Answer 1

value 的值要与 addressModel的类型匹配，addressModel是字符串，而value是对象，v-model指令自然不能正常工作，看代码，你是想用对象做匹配，建议使用对象的id来做匹配，

v-model="JSON.parse(addressModel).id"

:value="item.id"
