I have this code to capture all clicks on the document:
document.observe("click", function(this) {
alert(this.id);
Its throwing an error saying missing formal parameter, pointing at the
this reference in my function. I know i must be doing something wrong.
What i want to do is alert out the id ( if any) on whatever has been
clicked on.
Any ideas?

"this" is a keyword, it can not be used as a function argument. Choose any other valid name and you''ll be just fine. - kangax --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Spinoffs" group.

aha of course...thanks....unfortunately it doesnt seem to work....i
get an alert back every time i click but its always undefined....i''ve
posted it in the context of the rest of my code just in case something
else might be causing the problem....the bit directly concerned is at
the bottom
document.observe("dom:loaded", function() {
var forms = $$(''select'');
var container = $(''container'');
forms.each(function(select, index) {
select.hide();
var ul = new Element(''ul'', { id:
''list_'' + (index +1) +
''_body''});
var options = select.select("option");
options.each(function(option) {
var li = new Element(''li'');
var anchor = new Element(''a'', {class:
''listelement''}).update(option.innerHTML);
li.appendChild(anchor);
ul.appendChild(li);
container.appendChild(ul);
});
var aTag = new Element(''a'', { id:
''list_'' + (index +1), class:
''selectelement'', href:''#''
}).update(''select...'');
container.appendChild(aTag);
})
document.observe("click", function(itt) {
alert(itt.innerHTML);
})
})

Event handler (in this context) gets event object as a first
argument.
This event object does NOT have innerHTML property.
Since you are using 1.6, a preferred way to access element is via
"this",
event.element() or event.target.
document.observe(''click'', function(event) {
alert(event.element().innerHTML);
// or
alert(this.innerHTML);
...
})
