Its not much different, but this is what i do:
if ( $('some_button') ) {
$('some_button').observe('click', function (e) {
//do stuff.
});
}
Ideally, i wish prototype was a bit more strict about this stuff...
If you're using Firebug, you could replace your $() definition:
function $(element) {
if (arguments.length > 1) {
for (var i = 0, elements = [], length = arguments.length; i < length;
i++)
elements.push($(arguments[i]));
return elements;
}
* if (Object.isString(element)) {
var _element = element;
element = document.getElementById(element);
if ( element == null ) {
console.log('"' + _element + '" is null or does not exist');
return;
}
}
* return Element.extend(element);
}
