Question

我在 material-ui/lab 中使用自动完成组件我所做的是检查用户是否已经定义了一个值。例如。用户可以在模态中编辑输入，然后用用户选择的选项预填充自动完成）

在这种情况下，我正在传递记录中的值，但它向我发出以下警告。

<configuration>
    <excludes>
        <exclude>
            <groupId>org.projectlombok</groupId>
            <artifactId>lombok</artifactId>
        </exclude>
    </excludes>
</configuration>

这是我的自动完成组件

问题是如何删除这个 getOptionSelected 警告。我正在使用 getOptionSelected 检查国家 ID 是否与选项匹配。

虽然不是错误，只是警告，但似乎影响了系统速度。

提前致谢

问题取决于您对 "" 的回退：

countryList.filter((item) => {
  return item.countryId === values.countryId;
})[0] || ""

您得到的错误是当值为 "" None of the options match with "" 时，因为它会尝试针对 getOptionSelected 运行 ""。

getOptionSelected={(option, value) =>
  option.countryId === value.countryId // Here, option is ""
}

自动完成材质 UI getOptionSelected 警告
