Thanks again david and Alex.
I looked but could not find the code to check to see if the variable
held an instance or was null.
myInstance=new Ajax.PeriodicalUpdater(
TO check it ...
If(myInstace) {
do some code here
}

Gee, that is easy, no wonder I couldn't find it :-)
I am more used to PHP so I was looking for something like if
(isset(myinstance))
should be a piece of cake.
Hi,
I also think delegation is the better approach.
However, I did notice that none of the examples was dealing with the
case where the user click on something that is not a '.item'.
You may want to do something like this:
function doIt(e) {
var element = e.findElement('.item');
if(element
I suspect this is not a prototype question, but then again, every time I
turn around I am learning new capabilities of the framework.
I need to pass a function name as an argument to a function for a
call-back function.
Do I just pass the function name as a quoted text argument ?
If I do, do I
Not sure what u mean Bill...
Are you reffering to somehting like the onComplete of Ajax.Updater...
If so there is 2 ways to do it..
1. onComplete: myFunction (then somewhere else)
function myFunction() {
alert('i got called');
}
OR
2. (Anonymous Function)
onComplete : function() {
alert('I
Sorry i get what u mean now!..
Example:
function myFunction(options) {
alert(options.id);
eval(mySecondFunction);// Be very aware that evaluation is bad as JS can be
injected if you do not sanitise strings correctly
}
myFunction({id:1234,callback:'mySecondFunction'});
// alerts 1234 then

Hello, I am using a local autocomplete and everything is working fine
except when I search using the IN letters. When I search like that,
the drop down menu show the first match and then other 9 items that do
not match the search. This is only happening with this string. I think
this maybe because
Hi Bill,
If I'm reading you right, you want to pass a callback into another
function. Functions are first-class objects in JavaScript so there's
nothing special you need to do (and certainly no need for eval).
Say you have a logging function:
function logMsg(msg) {
alert(msg); //
Nobody an idea how to limit sortable lists?

Although it's very uncommon (and generally bad practice) in a web app
to have really blocking events (since users can navigate away from a
page or close the window while the request is running), if you really
want to do that, you have to make sure the user isn't able to click
anything else

I have several draggables and several droppables on the page. Using
script.aculo.us, I have the ability to put draggables into droppables.
I'm using this code for the onDrop to achieve this:

dragged.style.top = 0;
dragged.style.left = 0;
