I am working on a class now and part of the initialization is adding
event listeners to an object. I'd like to pass some value through to
the functions that are attributes of the class but I can't seem to
figure it out. Here's a sample piece of the code:
var MyClass= new Class.create();
I am trying to get a short list of supervisors into a form based on a
selection off_name in an Autocompleter, also in that form.
The code below worked until I added the getOfficerData() function,
passing an index value returned in the li as li.id.
I started getting update not defined errors in
Hi,
Since you're creating the event handler inside your `initialize`
function, you can take advantage of the fact it's already a closure by
assigning `this` to a local variable (`self` is a common name for it)
and then using `self` within the closure (the event handler), since it
will inherit it.
Hi,
`update` isn't a global symbol, you either need `Element.update` or an
element instance on which you call `.update`, e.g.:
var id = foo;
Element.update(id, pHi there/p);
// -or-
$(id).update(pHi there/p);
(In the latter case, it doesn't have to be looked up by ID, as long
The second form $(id).update(pHi there/p); seems most
appropriate, but my element is a form field, oid of the element $
('eventform'). Firebug shows me that it hasn't processed an update
because it sends my default value of $('eventform').oid to the
server. So I think the $(id) part is the
You can just add parameters to the bind call and they will show up in
execution.
$(id).observe('mousedown', this.myFunction.bind(this, otherParam);
Then I believe it shows up after the event.
function myFunction(event, param){...
but in your case, simply binding to this will allow you to
I did something similar in that I just patched Ajax.Request with some
extra functionality to allow timeouts, I never fussed with it further
than fundamental tests but it certainly worked. Take a peak and maybe
you can learn how to write something to meet your own needs
just store the reference to the listener and re-attach it to the
element after the user has successfully purchased more comment tokens
or whatnot.
var myListener = function(){};
$(button).stopObserving();
//.. user buys tokens...
$(button).observe('click', myListener);
