jQuery Fx.frame (among others) problem

[IGx89]

The problem is that the jQuery adapter doesn't handle "from" arguments in its animation method. It is most easily brought to light when using the Fx.frame method, because the animation element's left and top attributes default to auto and then jQuery chokes when trying to parseInt them.

Here's my partial, unoptimized fix for Ext v1.1b1 (in jquery-bridge.js, inside Ext.lib.Anim):

        run : function(el, args, duration, easing, cb, scope, type){
            var anim = createAnim(cb, scope);
            var o = {};
            for(var k in args){
                switch(k){   // jquery doesn't support, so convert
                    case 'points':
                        var by, pts, e = Ext.fly(el, '_animrun');
                        e.position();
                        if(by = args.points.by){
                            var xy = e.getXY();
                            pts = e.translatePoints([xy[0]+by[0], xy[1]+by[1]]);
                        }else{
                            pts = e.translatePoints(args.points.to);
                        }
                        o.left = pts.left;
                        o.top = pts.top;
                        if(!parseInt(e.getStyle('left'), 10)){ // auto bug
                            e.setLeft(0);
                        }
                        if(!parseInt(e.getStyle('top'), 10)){
                            e.setTop(0);
                        }
                    break;
                    case 'width':
                        o.width = args.width.to;
+                       Ext.fly(el, '_animrun').setWidth(args.width.from);
                    break;
                    case 'height':
                        o.height = args.height.to;
+                       Ext.fly(el, '_animrun').setHeight(args.height.from);
                    break;
                    case 'opacity':
                        o.opacity = args.opacity.to;
                    break;
+                   case 'left':
+                   	o.left = args.left.to;
+                       Ext.fly(el, '_animrun').setLeft(args.left.from);
+                   break;
+                   case 'top':
+                   	o.top = args.top.to;
+                       Ext.fly(el, '_animrun').setTop(args.top.from);
+                   break;
                    default:
                        o[k] = args[k].to;
                    break;
                }
            }
            // TODO: find out about easing plug in?
            jQuery(el).animate(o, duration*1000, undefined, anim.proxyCallback);
            return anim;
        }

Thanks I will check it tomorow.

Jack, has this made it into SVN yet? It'd be nice to have in 1.1 final...

Thanks iGx89, I will do some testing with this!

Ok, I made some changes and it appears to work great. It was indeed the lack of "from".

run : function(el, args, duration, easing, cb, scope, type){
            var anim = createAnim(cb, scope), e = Ext.fly(el, '_animrun');
            var o = {};
            for(var k in args){
                if(args[k].from){
                    if(k != 'points'){
                        e.setStyle(k, args[k].from);
                    }
                }
                switch(k){   // jquery doesn't support, so convert
                    case 'points':
                        var by, pts;
                        e.position();
                        if(by = args.points.by){
                            var xy = e.getXY();
                            pts = e.translatePoints([xy[0]+by[0], xy[1]+by[1]]);
                        }else{
                            pts = e.translatePoints(args.points.to);
                        }
                        o.left = pts.left;
                        o.top = pts.top;
                        if(!parseInt(e.getStyle('left'), 10)){ // auto bug
                            e.setLeft(0);

                        }
                        if(args.points.from){
                            e.setXY(args.points.from);
                        }
                    break;
                    case 'width':
                        o.width = args.width.to;
                    break;

                    break;
                    default:
