从 javascript 异步 function 获取状态回调

Question

I'm not so skilled on JS.

I'm importing a function from an external lib

import { doSomething } from '@/javascript/solana.ts';

Into this lib execute is defined in this way..

export async function doSomething(...) { 
 ....
 try {
  ... 
} catch (e) {
  ...  
}
}

In my code I need to catch for error and for success.

I have a function that call my imported function

function drawImages() {
  doSomething( ... ).catch(e => {
    console.log('There has been a problem with your fetch operation: ' + e.message);
  });
}

How can I manage the success?

Answer 1

Use Promise#then to handle the value returned when it is successful.

function drawImages() {
  doSomething( /* ... */ ).then(result => console.log(result)).catch(e => {
    console.log('There has been a problem with your fetch operation: ' + e.message);
  });
}
