I don't see why not. It doesn't violate the standard by *also* supporting non-standard extensions. (Though strictly speaking, the standard doesn't say attachEvent() doesn't exist so relying on its nonexistence is not standard-compliant; but that's nitpicking, since if W3C ever adds attachEvent() they're surely to make it MSIE-compatible). > But I haven't decided yet with what to replace attachEvent for example, > my best alternative right now is using the popular workaround I described... > Can anyone offer a better solution(I wish to create pages which are standard > as possible). The workaround is a very reasonable solution (as long as you wrap it up in a function and don't litter the whole page with conditionals). Where possible, include a piece of JavaScript that emulates the standard functionality using the MSIE functionality, and write the rest of the page in a strictly standard-conforming way. I wonder if you can tell MSIE to add an "addEventListener" method to all elements. If you have existing code you don't want to change, you can do it the other way around: emulate the MSIE functionality using the standard. Here's a set of scripts that does this for many MSIE quirks: http://webfx.eae.net/dhtml/ieemu http://webfx.eae.net/dhtml/mozInnerHTML/mozInnerHtml.html It claims to be Mozilla-specific, but I suspect it's actually standard-compliant or nearly so. Alas, it doesn't work well in Konqueror (e.g., the "setColor" demo at http://webfx.eae.net/dhtml/ieemu/js.html fails in Konqueror, even though it looks OK according to ECMAScript 3rd edition).
