An even more important performance gain can be had by
not doing string concatenation (I put a caveat about this in the code
comment's also), but build an array of your html and then join the
array; it's siginficantly faster.
Funny that you mention this. In current browser
Hi Michael,
It is working fine. Thank You Very Much.
Just one final question. This is part of a form.
When the form is submitted but not validated on the server I rebuild
the themes list.
There is only one problem: when I delete a theme all disappear.
I think it is because themes is being
You could post to the server with ajax, or since you have all the data
server-side, just render the page with the themes array already
populated and call the build function

I am not using Ajax because I need to submit the form all at once.
I cannot submit the themes because the user is not created yet.
Anyway, the other option you suggested me was what I was trying:
$test = $('#Test');
$test.append(themes);
Where Test would be an hidden input.

Hi Miguel, not sure if it will solve your problem, but I find it is
much faster to create a complete html string and then append it
instead of doing lots of appends, which are slow.
//this handles the li content
var li =
Creating a complete html string won't solve the current problem; it is
faster, and usually the way I prefer doing it also (see my note
further below though), but as I indicated in a code comment, since
this appears to be based on user input, the list (hopefully) won't be
very big, so the speed
@Michael,
I just installed Firebug and I almost made this working.
The only problem I have is when I am adding the levels to the list as
html and as hidden input:
+friendlyLevels(t[1].text.join(', '))+'br /'
$('input').attr({'type':'hidden','name':'Themes['+i
The problem is t[1] is now an array of objects, so you have to access
the text and value attributes of the objects by their array index.
Here are the buildThemesList function and the friendlyLevels functions
rewritten to account for that.
function buildThemesList(){
Hello,
I tried to make the change:
levels.each(function(){
levelsCsv.push({'text':this.value,'value':$(this).next().text()})
})
But I get an error on Firebug:
levels.each is not a function
Am I doing something wrong?
I also made a change on
P.S: I updated my example as usually:

That's because you changed levels to an object, which you don't need
to. Just use the original var levels = $('input:checkbox:checked'),
and then
levels.each(function(){

Hi,
I followed your tips but I still have a few problems.
The subject is working fine but when I do the same to the levels it
does not work.
I think the problem, but I am not sure, is in:
levels.each(function(){
levelCsv.push(this.value);//array to hold the levels
});
I changed
levels.text = $('input[name=Levels]:checked + label');
levels.value = $('input[name=Levels]:checked');
Those don't get you the right values for the levels object, they both
return a jQuery object.
Accessing the levels object as this.value won't work either.
Try this:
levels.each(function(){
Hi Michaell,
Sorry for the delay but when I started using JQuery 1.3 I solved this
problem but I got a few others on my application.
Anyway, there is just something else that I am not able to solve.
When I add a theme I need to:
1. For the Select (Subject), add the selected value to hidden
You could modify the subject variable being put into the array to make
it an object: subject = {}
then add the option's value and text to it:
subject.value = $('#Subject option:selected').val();
subject.text = $('#Subject option:selected').text();
or in one line to replace what's there now:

The problem is with the version of jQuery you're using. Update to 1.3
(and don't include a space in the URI).
Try your code with the Google js api and it will work (I just did,
even with the duplicate jQuery wrapper functions).

The function should be called, I think, after adding or removing an
item to reorder the ids.
Anyway, I created an example:

The problem is that I am not able to reorder the list so it is 0

Any idea?

That's because you have that empty li style=display:none/li. Is
it really necessary?
just decrement the index to start at 0:
$('#Themes li').each(function(index){
index--;
$('input:hidden', this).each(function(){
var fixName = $(this).attr('name').replace(/\[\d\]/, '['+index
+']');
Here's a wholly different approach for consideration. Rather than try
and keep track of LI elements and regex their names with the current
index, just use an array placeholder and rebuild the list. Chances are
if the user is required to add items, the list isn't going to get
unmanageably huge (at
You could remove the entire list everytime and regenerate it from
javascript. Is Themes[0].Subject the actual name, or are you trying
to refer to a javascript object in an array with the attribute
'Subject' which contains the name you are looking for? If it is the
latter, this won't work.
Themes[0].Subject is the actual name ... It is so to be read by an MVS
framework into a List.
Basically when the page loads some items are already there rendered on
the server.
They are always with the correct order.
However, when I add / remove items to that list the order might
change ...
So
At the risk of repeating myself from other posts, You might save
yourself future problems if you use standards-based id/name attributes
(and if the framework you're using doesn't allow that, seriously
consider a different framework):

I think your naming should be fine.because i sometimes use these kind of

Probably not the most efficient function, but should work:
$('#ThemesList li').each(function(index){
$('input:hidden', this).each(function(){
var fixName = $(this).attr('name').replace(/\[\d\]/, '['+index

$(this).attr('name', fixName);
