Just for reference, the way that I got this to work in Prototype 1.6
was (hopefully this accounts for all cases):
var prev = {};
["insert","remove","replace","update","wrap"].each(function(s){prev[s]
= Element[s]});
var add = {
insert: function(){
var args = $A(arguments), element = $(args.shift()), insertions
=
args[0], fireEs = [];
if (Object.isString(insertions) || Object.isNumber(insertions)
||
Object.isElement(insertions) || (insertions &&
(insertions.toElement || insertions.toHTML)))
insertions = {bottom:insertions};
for (position in insertions) {
position = position.toLowerCase();
if (position == "before" || position == "after")
{
fireEs.push($(element.parentNode));
}
else
{
fireEs.push(element);
}
}
var retVal = prev.insert(element, args);
fireEs.each(function(e){
fireE.fire("nodeadded");
fireE.fire("domchanged");
});
},
remove: function(){
var args = $A(arguments), element = $(args.shift()), fireE = $
(element.parentNode);
var retVal = prev.remove(element, args);
fireE.fire("noderemoved");
fireE.fire("domchanged");
return retVal;
},
replace: function(){
var args = $A(arguments), element = $(args.shift()), fireE = $
(element.parentNode);
var retVal = prev.replace(element, args);
fireE.fire("noderemoved");
fireE.fire("nodeadded");
fireE.fire("domchanged");
return retVal;
},
update: function(){
var args = $A(arguments), element = $(args.shift());
var retVal = prev.update(element, args);
element.fire("domchanged");
return retVal;
},
wrap: function(){
var args = $A(arguments), element = $(args.shift()), fireE = $
(element.parentNode);
var retVal = prev.wrap(element, args);
fireE.fire("nodeadded");
fireE.fire("domchanged");
return retVal;
}
}
Element.addMethods(add);
