Hi guys. I'm new in prototypejs and script.aculo.
But, lets consider Andrew Dupont's example again:
var f = new String("foo");
alert($(f)) //-> foo
alert(document.getElementById('foo')) //-> [object HTMLElement]
It has cause:
"When String( ) is used as a constructor with the new operator, it
returns a String object, which holds the string s or the string
representation of s. When the String( ) constructor is used without
the new operator, it simply converts s to a primitive string and
returns the converted value."
it's mean:
alert(typeof new String()) //-> object
alert(typeof String()) //-> string
Possible, it will be better to redefine $ like this:
function $(element) {
if (arguments.length > 1) {
for (var i = 0, elements = [], length = arguments.length; i <
length; i++)
elements.push($(arguments[i]));
return elements;
}
if (typeof element == 'string' || element instanceof String) //<-
NEW CONDITION
element = document.getElementById(element);
return Element.extend(element);
}
Or it isn't good idea. What do you think?
