我正在尝试在我的项目中实现 react-select。我的代码在这里：https://gist.github.com/BikalNepal/9172b3161abfa545cc5748055c6584c6

正在使用 graphql 获取搜索数据并从后端 nodejs 服务器中继，当我在框中键入时，它会正确获取数据，但是当我单击数据时，出现以下错误：

Option selected: {value: "stark@gmail.com", label: "rickon"}// Selected data is okay
Error:

The above error occurred in the <Select> component:

Consider adding an error boundary to your tree to customize error handling behavior.

这可能是什么问题？

【问题讨论】：

发生错误时，您检查过options 和value 状态吗？

标签： javascript reactjs react-select relayjs

【解决方案1】：

这里你引用了一个你从未声明过的event 常量。在您的代码下方已修复。请参阅道具onInputChange 和onKeyDown，您必须在发送之前致电event。

 <Select
   value={selectedOption}
   onChange={this.handleChange}
   options={this.state.options}
   // onKeyDown={event => this.handleRefetch(event)}
   onInputChange={event => this.handleInput(event)}
   inputValue={this.state.value}
 />
