jQuery是否承诺遵守Promises/A + [英] do jQuery promises conform Promises/A+
问题描述
我已阅读本文是基于著名的 Domenic Denicola的文章.第一个说:
I have read this article which is based on famous Domenic Denicola's article. The first one says:
jQuery的实现问题(直到1.9版)是 它不遵守规范的第二部分，这 函数应该返回一个新的promise…"，即然后"不返回 执行其中一个处理程序时，新的Promise对象( 填充，拒绝或进度处理程序).
The problem with jQuery’s implementation (up until version 1.9) is that it doesn’t respect the second part of the specification, "This function should return a new promise…", that is "then" doesn’t return a new promise object when executing one of the handlers (either the fullfillment, the rejection or the progress handler).
我发现了与该问题相对应的以下错误:
I have found these bugs corresponding to this problem:
- http://bugs.jquery.com/ticket/14510
- https://github.com/jquery/jquery/issues/1722
我的问题是:此问题的当前状态是什么?两者均已打开，因此工作仍在进行中.但是，使用jQuery 2，您可以使用.then链接promise.所以:仍然是jQuery.Promises实现坏了吗?自1.9版以来，有什么变化吗?
My question is: what is the current state of this issue? Both are opened, so the work is still in progress. But, using jquery 2, you can chain promises with .then. So: is still jQuery.Promises implementation broken? Did anything change since version 1.9?
推荐答案
更新:从jQuery 3.0开始，答案是是. jQuery Promise是Promises/A +兼容的，可以安全使用.
Update: As of jQuery 3.0 the answer is yes. jQuery promises are Promises/A+ compatible and can be safely used.
jQuery承诺当前不遵守Promises/A +规范，因此 有一些问题 ，Domenic的文章仍然有效.
jQuery promises do not currently adhere to the Promises/A+ specification and thus have some issues and Domenic's article is still valid.
表示正在进行中的工作已经完成，jQuery承诺最终将在下一个版本中符合Promises/A + .它仍在进行中此处是相关的提取请求和
That said active work is being done and jQuery promises will finally be Promises/A+ compliant in the next version. It's still work in progress here is the relevant pull request and here. The last bit of work on it was two days ago.
激动人心的时刻.
