Hey, I'm trying to get my pagination numbers to update when the user uses the filter options at the side of the page.
Here is what I'm working on: Click Here
The problem is, when you click the color - Yellow - you should only get 1 result(Giant) and only 1 page number should display. however the pagination is not updating properly and still displays all page numbers.
EDIT:
I have placed the paginateIt() function at the end of the filter script but now I get an unresponsive script warning
I have updated the script with my recent changes below:
$(document).ready(function(){
function paginateIt(){
//how much items per page to show
var show_per_page = 3;
//getting the amount of elements inside content div
var number_of_items = $('#content ul').filter(":not(.hidden)").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);
//now when we got all we need for the navigation let's make it '
/*
what are we going to have in the navigation?
- link to previous page
- links to specific pages
- link to next page
*/
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>';
$('#page_navigation').html(navigation_html);
//add active_page class to the first page link
$('#page_navigation .page_link:first').addClass('active_page');
//hide all the elements inside content div
$('#content ul').filter(":not(.hidden)").children().css('display', 'none');
//and show the first n (show_per_page) elements
$('#content ul').filter(":not(.hidden)").children().slice(0, show_per_page).css('display', 'block');
// Start filter script
