替换DOM3的getUserData / setUserData方法 [英] Replacement for DOM3 getUserData/setUserData methods

问题描述

因此，我们有一些旧版的Firefox扩展代码，使用 DOM3方法 get / setUserData（）传递DOM中的数据。很遗憾，这些网址已在DOM4中弃用，因此Firefox是计划停止支持他们，Chrome从来不支持他们。

So we've got some old-school Firefox extension code that uses the DOM3 methods get/setUserData() to pass around data in the DOM. Unfortunately, these have been deprecated in DOM4, so Firefox is planning to drop support for them, and Chrome never supported them in the first place.

是否有跨浏览器替换？ jQuery的 $。data 似乎是一个选项，但是纯粹的JavaScript是更可取的。

Is there a cross-browser replacement? jQuery's $.data seems to be an option, but 'pure' JavaScript would be preferable.

推荐答案

所以最后我们决定使用jQuery，核心库只有大约75k，它很清楚地解决了这个问题：

So in the end we decided to go with jQuery after all, the core library is only around 75k and it solves the problem very cleanly:

element.getUserData('foo') --> $(element).data('foo')

element.setUserData('foo', 'bar', null) --> $(element).data('foo', 'bar')
