Der Fix im Quellcode vom ckeditor ist dann effektiv dieser diff hier: diff --git a/plugins/floatingspace/plugin.js b/plugins/floatingspace/plugin.js index 8abbcd61d..65f16025b 100644 --- a/plugins/floatingspace/plugin.js +++ b/plugins/floatingspace/plugin.js @ -26,6 +37,7 @@ function attach( editor ) { var config = editor.config, + parent = parentScroll(editor.element), // Get the HTML for the predefined spaces. topHtml = editor.fire( 'uiSpace', { space: 'top', html: '' } ).html, @@ -312,6 +324,7 @@ editor.on( 'change', changeBuffer.input ); win.on( 'scroll', uiBuffer.input ); win.on( 'resize', uiBuffer.input ); + parent.forEach(function(element) { + element.on( 'scroll', uiBuffer.input ); + }); } ); editor.on( 'blur', function() { @@ -319,11 +332,13 @@ editor.removeListener( 'change', changeBuffer.input ); win.removeListener( 'scroll', uiBuffer.input ); win.removeListener( 'resize', uiBuffer.input ); + parent.forEach(function(element) { + element.removeListener( 'scroll', uiBuffer.input ); + }); } ); editor.on( 'destroy', function() { win.removeListener( 'scroll', uiBuffer.input ); win.removeListener( 'resize', uiBuffer.input ); + parent.forEach(function(element) { + element.removeListener( 'scroll', uiBuffer.input ); + }); floatSpace.clearCustomData(); floatSpace.remove(); } ); Das sucht sich beim attachen das Ziel Element, sucht sich das/die parent-Elemente die scrollbar sind, und registrtiert den scroll handler auf diesen Elementen. Leider gibt es keine Standardfunktion parentScroll() in javascript. Es gibt ein Plugin gleichen Namens für jQuery, die Funktion da liefert aber nur den nächst-höheren div und ausserdem ist jQuery innerhalb von CKEditor nicht verfügbar. Die hier implementierte Funktion ist identisch mit dieser hier, die angelehnt ist an das jQuery verhalten, aber pures Javascript benutzt: function parentScroll(e) { var position = e.$.getAttribute("position"), excludeStaticParent = position === "absolute"; return e.getParents().filter( function(parent) { var style = window.getComputedStyle(parent.$); if ( excludeStaticParent && style.position === "static" ) return false; return (/(auto|scroll)/).test( style['overflow'] + style["overflow-y"] + style["overflow-x"] ); }); }; Im Gegensatz zum jQuery Plugin macht diese Variante keine Prüfung darauf ob der Invokant selber "fixed" position hat, und liefert nicht nur das erste Element sondern alle Treffer. Das Ergebnis ist ein normales Javascript Array. Der Code hier ist minified und direkt in unsere Variante injiziert, muss also beim Upgrade reproduziert werden. Was hier nicht gefixt ist: Das Repositioning Verhalten von floatingspace orientiert sich weiter an Body, und nicht (wie eigentlich korrekt) am umliegenden scrolling div.
