如何在 react-hook-form 中的 react-select 中从 useEffect 获取条件默认值？
How to have conditional defaultValues from useEffect in react-select within react-hook-form?
我正在使用包含 react-select CreatableSelect multiselect 输入的 react-hook-form 处理表单。 multiselect 用于给定 post 的标签，它是有条件的，取决于用户 select 是否更新现有 post.[=28 的标签=]
我的问题是，当用户 select 现有 post 包含标签时，multiselect 的默认值不起作用。
总体流程是：用户 select 现有 post（在我的示例中为 PublicShareNetworkSelect） > onChange 函数更改存储在挂钩中的 post ID（selectedNetwork 在我的示例中）> selectedNetwork 中的更改会触发 getNetworkData 函数，该函数设置用作 multiselect defaultValue
的标签变量 (networkTags)
另外，getTags() 函数用于填充 multiselect 中的 options。
我认为这个问题与从 API 获取数据有关，因为我试图创建一个 minimum reproducible example，但它在没有 axios 调用的情况下完全按照我想要的方式工作。但是，当我在我的完整示例中 console.log allTags 和 networkTags 时，数组中有匹配的对象（匹配应该是默认值）。

问题是，defaultValue 在第一次渲染时被缓存。这同样适用于 defaultValues 属性 传递给 useForm.
Important: defaultValues is cached at the first render within the custom hook. If you want to reset the defaultValues, you should use the reset api.
正如文档中引述的那样——您必须使用 reset。我相应地修改了你的例子。看看here。如您所见，我正在异步重置表单并且它有效。
此外，请注意 Controller 的 render 道具 - 我将传递给定的所有道具，而不仅仅是 onChange。之所以如此，是因为这里还有其他重要的东西（比如 value）。通过将您的组件包装在 Controller 中，您必须至少提供 onChange 和 value 对。
