javascript 等待来自api的回调

Posted 2021-05-03

function apiOn(event) {
  return new Promise(resolve => {
    api.on(event, response => resolve(response));
  });
}

async function test() {
  return await apiOn( 'someEvent' ); // await is actually optional here
                                      // you'd return a Promise either way.
}

async function whatever() {
  // snip
  const response = await test();
  // use response here
  // snip
}
