如何找到实现某些接口的函数的参数类型? [英] How do I find the parameter type of a function implementing certain interface?

问题描述

例如，我有一个

<form onSubmit={this.handleSubmit}>   
</form>

我需要实现handleSubmit功能.因此，我做

I need to implement the handdleSubmit funciton. Therefore, I do

 handleSubmit(event:any) {
      this.setState({ password: event.target.value });
 }

对于我不知道的参数类型，我总是将其放在上面.有没有一种方法可以找到传递参数的类型，而不是放置任何参数?

For the type of a parameter I do not know, I always put any on it. Is there a way to find the type of the passing parameter instead of putting any?

推荐答案

Dom事件在

Dom events are defined in lib.dom.d.ts, see WindowEventMap, GlobalEventHandlersEventMap, WindowEventHandlersEventMap

interface GlobalEventHandlersEventMap {
    "abort": UIEvent;
    "animationcancel": AnimationEvent;
    .....
    "submit": Event;
    .....
    "waiting": Event;
    "wheel": WheelEvent;
}
