q.js :是否可以知道承诺是否已解决/拒绝 [英] q.js : Is it possible to know if a promise has resolved/rejected or not

问题描述

在我的场景中，我在提出请求时返回一个 promise.

In my scenario I return a promise when I'm making a request.

最后我解决/拒绝了延迟的对象.

In the end I resolve/reject the deferred obj.

如果尚未解决/拒绝，我想重用承诺.

I want to reuse the promise if it hasn't been resolved/rejected.

任何信息都会有用.

推荐答案

我通过查看 q.js 源得到了答案.

I got the answer by looking into q.js source.

deferred.promise.inspect().state

这将返回承诺的状态.

returns "fulfilled" if it was resolved or fulfilled
returns "rejected" if it was rejected
returns "pending" if it hasn't been resolved or rejected
