jQuery.fn.pagination = function(maxentries, opts) {
opts = jQuery.extend({
items_per_page: 10,
num_display_entries: 10,
current_page: 0,
num_edge_entries: 0,
link_to: “#”,

return this.each(function() {
/**
* Calculate the maximum number of pages
*/
function numPages() {
return Math.ceil(maxentries / opts.items_per_page);
}

/**
* Calculate start and end point of pagination links depending on
* current_page and num_display_entries.
* @return {Array}
*/
function getInterval() {
var ne_half = Math.ceil(opts.num_display_entries / 2);
var np = numPages();
var upper_limit = np – opts.num_display_entries;
var start = current_page
