cqan i chain this code together in prototype?

Hi,

 I had this code:
 var newCopy = new Element(''div'', { ''id'' :
obj.id, ''class'' :
''de_small'' }).update(obj.innerHTML);

which worked fine but now i add this and it breaks my script...it''s
hard to explain exactly how it breaks but it involves a draggable
object not being droppable anymore

var newCopy = new Element(''div'', { ''id'' :
obj.id, ''class'' :
''de_small''
}).update(obj.innerHTML).observe(''click'', deleteThis());

can i not do it like this?

Re: cqan i chain this code together in prototype?

HI There,

Yes the new element is being inserted later ( $
(dropZoneCount.id).appendChild(newCopy);)....that''s all working
fine....i only posted the relevant code....the bit of code when it was
working and then the same bit of code with the extra code taht breaks
the script. Can you see anything wrong with it?

Re: cqan i chain this code together in prototype?

Looking at this brief snippet I see one potential error,  You''re
executing your callback, try sending just the reference.

Re: cqan i chain this code together in prototype?

In other words, change:

.observe(''click'', deleteThis());

To:

.observe(''click'', deleteThis);

You''re passing deleteThis() as the value of your callback, which
isn''t
a function, but the return value of calling it.

Re: cqan i chain this code together in prototype?

Ah What about in the event that i need to feed a parameter to the
function??
 like: .observe(''click'', deleteThis(param));

I wouldn''t mind just running the funcion from here:

 var newCopy = new Element(''div'', { ''id'' :
obj.id, ''class'' :
''de_small''
}).update(obj.innerHTML).observe(''click'', function{(...)};

(so just have the function code just after click...like above) ...but
i don''t know if you can do it/get the syntax right

Re: cqan i chain this code together in prototype?

Just wrap in another function:

.observe(''click'', function(){ deleteThis(param) });

Or:
