This could be useful for parsing Element#getStyle results (to get rid
of "px")
parseInt(element.getStyle('left'));
// vs.
element.getStyle('left').parseInt();
I don't think it's a significant difference though. Moreover, getStyle
could return null and we all know what happens then. Speaking about
getStyle and parseInt, we had to do a little trick in Prototype UI:
Element.addMethods({
getNumStyle: function(element, style) {
var value = parseInt($(element).getStyle(style));
return isNaN(value) ? null : value;
}
})
