打字稿强类型void功能

Question

I'm trying to write an interface which takes a function in as a parameter: 我正在尝试编写一个将函数作为参数的接口：

Currently I'm trying this 目前我正在尝试

export interface EditOptions {
     isEditing: boolean;
     save: () => {};
}

I've tried a few things to assign the function: 我尝试了一些分配功能的方法：

editOptions: EditOptions = { isEditing: false, save: this.save };
editOptions: EditOptions = { isEditing: false, save: () => { this.save() } };

Neither work instead I receive this error: 两者都不起作用，但我收到此错误：

I Know that for now I can use :any but what is the proper way to strongly type a void function 我知道现在我可以使用:any但是强类型键入void函数的正确方法是什么？

Answer 1

interface you can define as : 您可以将接口定义为：

export interface EditOptions {
 isEditing: boolean;
 save: () => void;
 }

and you can use/assign it as : 您可以将其使用/分配为：

editOptions: EditOptions = { isEditing: false, save: () => { this.anyFunction() } };
