function reflect(promise){ return promise.then(function(v){ return {v:v, status: "resolved" }}, function(e){ return {e:e, status: "rejected" }}); } var promises = [promise1, promise2, promise3]; Promise.all(promises.map(reflect)).then(function(results){ // do something });
【备忘录】Promise.all包含rejected状态的多个promise完成后执行事件
