在node.js中永远重复这一组操作

我正在使用node.js 我有这个function，它使用承诺在执行某些操作之间引入延迟。

function do_consecutive_action() { Promise.resolve() .then(() => do_X() ) .then(() => Delay(1000)) .then(() => do_Y()) .then(() => Delay(1000)) .then(() => do_X()) .then(() => Delay(1000)) .then(() => do_Y()) ; } 

我想要做的就是让这一套行动永远重演。 这怎么能在node.js中完成？

 //make following actions repeat forever do_X() Delay(1000) do_Y() Delay(1000) 

编辑：我开始赏金的答案，使用重复队列来解决问题。

Answer 1

只要使用recursion

 function do_consecutive_action() { Promise.resolve() .then(() => do_X() ) .then(() => Delay(1000)) .then(() => do_Y()) .then(() => Delay(1000)) .then(() => do_consecutive_action()) // You will also want to include a catch handler if an error happens .catch((err) => { ... }); } 

Answer 2

 function cb(func) { try { func(); } catch (e) { do_consecutive_action(); } } function do_consecutive_action() { Promise.resolve() .then(() => cb(do_X)) .then(() => Delay(1000)) .then(() => cb(do_Y)) .then(() => Delay(1000)) .then(() => do_consecutive_action()) // You will also want to include a catch handler if an error happens .catch((err) => { ... }); 

}
