Element UI Select下拉框编辑时回显已删除数据的解决方案

代码实现示例

<el-form-item label="是否激活" prop="activationId">
    <el-select
        v-model="formParams.activationId"
        style="width: 140px"
        clearable
        placeholder="请选择"
    >
        <el-option
            v-for="item in activationList"
            :key="item.id"
            :label="item.name"
            :value="item.id"
        />
        <el-option
            v-if="!activationList.some(list=> list.id === formParams.activationId)&&formParams.activationId!==''"
            :label="formParams.activationName"
            :value="formParams.activationId"
         />
    </el-select>
</el-form-item>
export default {
  data () {
    return {
        formParams:{
            //回显被删除的id
            activationId:1,
            //回显被删除的name
            activationName: '已激活'
        },
        activationList: [
            //此处注释掉，假设第一条数据被删除
            //{id: 1, name: '已激活'},
            {id: 0, name: '未激活'}
        ]
    }
  }
}
