Mozilla 0.9.8 works - but no configuration option to disable windows opening - UAAG violation AIUI Any browser with Proximitron (this does the same as Snufkin, but is probably used by more than 3 people! I believe other similar proxy window.open blockers do the same) it fails - no-op the reason is to prevent javascript errors, they return a reference to the current window when they supress window.open - so you can't detect - you could perhaps do: window.name="moomin" windowref=window.open('','snork') if (windowref && windowref.name=='snork') return false return true but I can still see that failing my snufkin it does fail in (I don't let people name my windows) but that's me, and you can probably forget about me. > > and self.focus() is not a solution in many scenarios, and is a > > WCAG 1.0 A > > violation, so is clearly not an option. > > Can you give me a chapter-and-verse on that? I apologise, that was of course my mistake it's a UAAG requirement (guideline 5), of course browsers aren't UAAG compliant in this, so I'd certainly want to be kind to the users. My own memory was effected by the fact this is a usability problem for me. > Of course, opening new windows at all ("until > user agents" yadda yadda) is a violation, so we're probably moot. Indeed, my other prohibition was that it simply doesn't work - almost every window manager prevents applications taking control of focus - of course in that situation nothing bad probably happens. > I think you are too ready to ascribe godlike qualities to human > spec/guideline authors. using a target attribute and not returning false is a much safer method: <a href="moomin.html" onclick="this.target='moomin';if (window.open) window.open('','moomin');"> [1] Seems to me to be much safer - of course - I'd use a HTML dtd that allowed me a target attribute, but if you really don't want to the above seems much safer.
