你在打字稿界面中给一个带孩子的对象提供什么类型

Question

I have a response

filereader.onload = function(evt: any) {
  url = evt.target.result; //sending the link to url
};

But considering the fact that removing type any makes the application faster. I tried giving the vet parameter the type of object but then the property target did not exist on type object. I also tried using an interface but giving it any still brings the same issue I am trying to get rid of.

Answer 1

The following inline type should do the trick:

filereader.onload = function(evt: { target: { result: string } }) {
  url = evt.target.result; //sending the link to url
};
