so.. im tryign to paginate a div with content being added by an input. but its not working at all...

first, I got this input:


<form name="postbar_add_post" id="postbar_add_post" method="post">
<fieldset>
<legend>What chu doign? ...</legend>
<input type="text" name="addcontentbox" id="addcontentbox" maxlength="200" />
<input type="submit" name="addpost" value="Submit" class="submit" />
</fieldset>
</form>

then, what i will happen is that, the content being submited, will be posted to an unsorted list, named wall, i used jquery to help me out on this, heres the script:


<script type="text/javascript">
$(document).ready(function(){
$("form#postbar_add_post").submit(function() {
var addcontentbox = $('#addcontentbox').attr('value');

if ( addcontentbox.replace(/\s/g,"") == "" ) return false;

$.ajax({
type: "POST",
url: "postear.php",
data:"addcontentbox="+ addcontentbox,
success: function(){
$("ul#wall").prepend("<li>"+addcontentbox+"</li>");
$("ul#wall li:first").fadeIn();
document.postbar_add_post.addcontentbox.value='';
document.postbar_add_post.addcontentbox.focus();
}
});
return false;
});
});
</script>

the div where it is beign opsted at, looks like this:


<div id="cuerpo"><ul id="wall"></ul></div>


adn then, below i got this div, wich is where the navgiation links will be at:
(before u read, "current_page" and "show_per_page" are 2 hidden inputes to save the values.)


<div id="navwrapper"></div>

so, to make the navigation, i found a script online and tried to adapt it to the div, i got this:



$(document).ready(function(){

//how much items per page to show
var show_per_page = 5;
//getting the amount of elements inside content div .
var number_of_items = $('#wall').children().size();
//calculate the number of pages we are going to have
var number_of_pages = Math.ceil(number_of_items/show_per_page);

//set the value of our hidden input fields
$('#current_page').val(0);
$('#show_per_page').val(show_per_page);


//navigation '


var navigation_html = '<a class="previous_link" href="javascript:previous();">Prev</a>';
var current_link = 0;
while(number_of_pages > current_link){
navigation_html += '<a class="page_link" href="javascript:go_to_page(' + current_link +')" longdesc="' + current_link +'">'+ (current_link + 1) +'</a>';
current_link++;
}
navigation_html += '<a class="next_link" href="javascript:next();">Next</a>';

$('#navwrapper').html(navigation_html);

//add active_page class to the first page link
$('#navwrapper .page_link:first').addClass('active_page');

//hide all the elements inside content div
$('#wall').children().css('display', 'none');

//and show the first n (show_per_page) elements
$('#wall').children().slice(0, show_per_page).css('display', 'block');

});

function previous(){

new_page = parseInt($('#current_page').val()) - 1;
//if there is an item before the current active link run the function
if($('.active_page').prev('.page_link').length==true){
go_to_page(new_page);
}
}

function next(){
new_page = parseInt($('#current_page').val()) + 1;
//if there is an item after the current active link run the function
if($('.active_page').next('.page_link').length==true){
go_to_page(new_page);
}
}

function go_to_page(page_num){
//get the number of items shown per page
var show_per_page = parseInt($('#show_per_page').val());

//get the element number where to start the slice from
start_from = page_num * show_per_page;

//get the element number where to end the slice
end_on = start_from + show_per_page;

//hide all children elements of content div, get specific items and show them
$('#wall').children().css('display', 'none').slice(start_from, end_on).css('display', 'block');

/*get the page link that has longdesc attribute of the current page and add active_page class to it
and remove that class from previously active page link*/
$('.page_link[longdesc=' + page_num +']').addClass('active_page').siblings('.active_page').removeClass('active_page');

//update the current page input field
$('#current_page').val(page_num);
}



but all looks cool but... it is actually not working... everything its being posted great to the unsorted listt, but its not paging =S. .. it just all shows on the div, and scrolls.

Could it be somethign on the css? ... or... what ...? =|


Guidance? =( . my brains toasted. =\
