打字稿事件类型注释

Question

如何为该事件提供正确的类型注释？

控制台：

{
 originalEvent: InputEvent {isTrusted: true, data: " ", isComposing: false, 
 inputType: "insertText", dataTransfer: null, …}
 value: " "
 __proto__: Object
}

打字稿代码：

const InputEvent = (event: ??? ) => console.log(event)

有没有办法将preventdefault函数附加到此？

Answer 1

InputEvent.ts文件

export class InputEvent {
   isTrusted: boolean;
   data: string;
   isComposing: boolean;
   inputType: string;
   dataTransfer: string;
   //and whatever more variables you have.
}

您可以这样定义它。

const InputEvent = (event: InputEvent ) => console.log(event);
