Oh, the reason I used a function instead of:
extraParams: {catID:categoryID},
is because the function acts as a callback that will execute right
before the AJAX call to get the updated data for categoryID, otherwise
it will just be the same as the URL, set only on initialization (which
is blank).
It's not really a variable scope problem. You're misunderstanding when
variables are set.
This is what's happening:
set global variable categoryID
add change event
add autocomplete with URL set to aloha/item_search/"+categoryID
-> categoryID is blank
do rest of page
When you do your change e
I haven't tested this, nor tried it before, but based on the
documentation the data type of extraParams has to be an object, or a
function (that probably returns an object).
function getCategoryID() {
return {catID:categoryID};
// 'catID' will be the name of the categoryID in your script
Thank you James for the help! I didn't know that the address is
static once you've initialized it. I'm trying to work with the
extraParams option but it doesn't seem to do anything. Here is how I
have it set:
//Item Search for food name

In this line of code:
> $('.menu_button').click(this.onClick);
you are getting a refernece to your onClick function. But that's all you get
- a *function* reference. It doesn't remember that you said 'this.onClick'
to get that reference.
As you found, when that function gets called later by jQu
Thank you Mike! It works perfect now.
The problem is the use of 'this' in the inner function. In that code it no
longer means what you want it to mean. Try this (pun intended) instead:
$('a[href^=logmar]').queue(function(){
var $this = $(this);
var args = $this.attr("href").split('?')[1];
if(args.charAt(0) ==
After getting a good nights sleep, and doing more research, it seems
the problem is not scope-related, but ajax-related. The advice I have
read suggests setting return values from within the ajax callback
function, because of the asynchronous completion of the ajax function.
So, I have attempted t

Hi,
I'm pretty new to jQuery. I'm having a problem with variable scope.
This function always returns false. The success variable is not being

Hoping someone can help me out with this. I'd appreciate any help.
There must be something else going on with your code other than the snippet
you've posted here. It's hard to believe that a local variable would not
work properly in Firefox.
If you could post a link to a complete test page, I'll bet someone could
tell you what is going wrong.

Wow I'm chatty aren't I...
I just wanted to add I changed my code to this
$(function() {
$.ajax({
type: "GET",
url: "xml/location.xml",
One thing I do notice with my code is that it is slow. If I change
provinces and type in the city field and change provinces again things
slow right down. I know this must be due to the way I have coded this.
I am wondering if you have any suggestion to improve the speed of
things? The form will p
Hi Micheal,
Thank you so much for that. I knew I was getting close to a solution
but I was well and truly stuck. It is now working and I am delighted.
This is the code that worked for me
success: function(xml) {
towncity = [];
$(xml).find("[EMAIL PROTECTED]'"+ currprov +"'] > TO
Hi Mat,
1) You're defining towncity like this:
var towncity = window.towncity = new Array();
That creates both a local variable named towncity and a window property
(global variable) of the same name. Is that what you want? Do you need to
use towncity outside this code? If not, I would chan
I tried it out and it fixes the problem - thanks a ton Michael!
Thanks Michael.
I'll try that out and see where I get!
A loop doesn't "print out" the code.
A function call *does*, in a manner of speaking.
I didn't look at the rest of your code in any detail, but if you want the
loop to work more the way you're expecting, where it saves the individual
loop values for "i" and the other variables you set up inside
Sorry about that MorningZ. My original question actually had to do
with whether somehow the value of the variable was being lost because
of the fact that when I went to actually use the variable it was
nested inside some other code blocks but what Dave said answers my
question.

There are a lot of plugins that do this, like tooltip, cluetip and

So what exactly is the question/problem with "variable scope"?
Are you losing the scope somewhere?
Are you asking if there's a better way?
it's not clear at all
