Replacement for DOM3 getUserData/setUserData methods

阅读更多关于 Replacement for DOM3 getUserData/setUserData methods

问题 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. Is there a cross-browser replacement? jQuery's $.data seems to be an option, but 'pure' JavaScript would be preferable. 回答1: So in the end we decided to go with jQuery after all, the core library is only around 75k

DOM Level 3 XPath in Internet Explorer

问题 I just installed IE10 on my Windows 7, and I've noticed that, even if I'm glad that XMLs from AJAX requests are now compatible DOM documents, a rather basic function like document.evaluate is still not supported.

So I did a search on here on SO and

Since DOM mutation is marked as deprecated by the w3c (see http://www.w3.org/TR/DOM-Level-3-Events/#events-mutationevents ), is there an (fast) alternative way to detect attribute modification in the DOM ? As far as I know there is no alternative (yet) so you are stuck with DOMAttrModified which is only supported in Firefox and Opera. In IE you have the onpropertychanged event but there is no way to get similar functionality in Chrome/Safari. There are a number of things you could do depending on what you are trying to accomplish and the browsers you are targetting: define getters and setters

问题 Why is the DOMSubtreeModified event deprecated and what are we supposed to use instead? 回答1: If you scroll down a bit, you see: Warning! The MutationEvent interface was introduced in DOM Level 2 Events, but has not yet been completely and interoperably implemented across user agents. In addition, there have been critiques that the interface, as designed, introduces a performance and implementation challenge. A new specification is under development with the aim of addressing the use cases
