As long as we're using Function and String extensions and Element methods from Prototype.js - someone should keep an eye out for relevant prototype.js bug fixes.
Between 2007/1/18 and 2007/6/20, prototype changed its Element.getStyle method from
getStyle: function(element, style) {
element = $(element);
if (['float','cssFloat'].include(style))
style = (typeof element.style.styleFloat != 'undefined' ? 'styleFloat' : 'cssFloat');
style = style.camelize();
var value = element.style[style];
if (!value) {
if (document.defaultView && document.defaultView.getComputedStyle) {
var css = document.defaultView.getComputedStyle(element, null);
value = css ? css[style] : null;
} else if (element.currentStyle) {
value = element.currentStyle[style];
}
}
if((value == 'auto') && ['width','height'].include(style) && (element.getStyle('display') != 'none'))
value = element['offset'+style.capitalize()] + 'px';
if (window.opera && ['left', 'top', 'right', 'bottom'].include(style))
if (Element.getStyle(element, 'position') == 'static') value = 'auto';
if(style == 'opacity') {
if(value) return parseFloat(value);
if(value = (element.getStyle('filter') || '').match(/alpha\(opacity=(.*)\)/))
if(value[1]) return parseFloat(value[1]) / 100;
return 1.0;
}
return value == 'auto' ? null : value;
},
to
getStyle: function(element, style) {
element = $(element);
style = style == 'float' ? 'cssFloat' : style.camelize();
var value = element.style[style];
if (!value) {
var css = document.defaultView.getComputedStyle(element, null);
value = css ? css[style] : null;
}
if (style == 'opacity') return value ? parseFloat(value) : 1.0;
return value == 'auto' ? null : value;
},
This seems relevant. There are likely other changes.
