問題描述

參數連接問題。我該如何處理 (parameter connection problem. How can I deal with this)

不幸的是，我的理解混亂了。

function sendRequest(data: string, cb: (response: any) => void) {
  return cb({ data: "Hi there!" });
}

sendRequest("Send this!", response => {
  console.log(response);
  return true;
}

我以為結果是{“發送這個！” : "Hi there!} 但答案是 {data : "Hi there!"}

什麼參數“data”不能連接到對象內部的數據？如果我想要這個結果，我應該改變什麼？

參考解法

方法 1:

If you wanna do that, you could do:

function sendRequest(data: string, cb: (response: any) => void) {
  let result = {};
  result[data] = "Hi there!";
  return cb(result);
}

sendRequest("Send this!", response => {
  console.log(response);
  return true;
});

方法 2:

This behavior is due to your object understanding data as the name of the key and is not trying to get the content of the variable. You need to put [data] so it will resolve to the string inside your variable. You can just do this : return cb({ [data]: "Hi there!" });
