如何将jQuery Deferred对象转换为ES6 Promise [英] How to convert a jQuery Deferred object to an ES6 Promise

问题描述

这是转换jQuery Deferred 的正确方法吗？到 承诺 ？

Is this the correct way to convert jQuery Deferred to a Promise?

var p = Promise.resolve($.getJSON('api/values', null));

还有其他方法吗？

有什么限制？我已经读过某个地方，jQuery延迟不支持异常，所以我假设从延迟创建的承诺都不会。它是否正确？

What are the limitations? I've read somewhere that jQuery deferred does not support exceptions, so I assume that a promise created out of a deferred would neither. Is this correct?

推荐答案

是的，Promise.resolve（）API支持thenable作为参数。所以传递一个jquery defer对象就可以了。

Yes it should, the Promise.resolve() API supports thenable as argument. So passing a jquery defer object would work just fine.
