Either way is fine, it just needs to be clarified. if SVGViewSpec is just a copy of the original and never changes once copied, that's easier to implement. One possible implementation problem if it tracks changes to SVGSVGElement, is what happens when that SVGSVGElement is removed from the document? Do then all of the viewPort, targetElement, preserveAspectRatio accessors then go undefined? var svg = document.getElementById("mysvg"); var currentView = svg.currentView; var svgParent = svg.parentNode; svgParent.removeNode(svg); alert(currentView.targetNode); // does this still work? One particularly thorny side effect of them *not* changing to undefined is that targetElement could be used to re-insert the SVGSVGElement, example: svgParent.removeNode(svg); svgParent.appendNode(currentView.targetNode.ownerSVGElement); Or equally fun to implement, I assume targetNode should at least update when nodes come and go from the document/change ids? Just looking for some guidance from you spec folks, thanks. 17179 1 494 eseidel 2007-10-14 05:29:54 +0000 Created attachment 494 an example test case of currentView "standard" behavior Note the test case is not stand alone and will not run in your browser. This test case assumes that SVGViewSpec objects *should* update when the original SVGSVGElement changes. 84410 2 dschulze 2013-03-14 13:28:48 +0000 Putting it into the scope of SVG2. It needs testing what current browsers do here. 84420 3 longsonr 2013-03-14 14:40:28 +0000 You mean should this animate? http://hoffmann.bplaced.net/svgtest/viewviewbox01.svg#view1 It does in Opera and Firefox. 84421 4 fmalita 2013-03-14 15:20:32 +0000 (In reply to comment #3) > You mean should this animate? > http://hoffmann.bplaced.net/svgtest/viewviewbox01.svg#view1 > > It does in Opera and Firefox. No, this is related to SVGViewSpec, as accessed via SVGSVGElement.currentView: http://www.w3.org/TR/SVG/struct.html#__svg__SVGSVGElement__currentView AFAICT currentView is not supported in FF19: Error: NS_ERROR_NOT_IMPLEMENTED: Component returned failure code: 0x80004001 (NS_ERROR_NOT_IMPLEMENTED) [nsIDOMSVGSVGElement.currentView] 84425 5 longsonr 2013-03-14 16:33:13 +0000 Oh that.
