jQuery pagination plugin

hi could you help me with jquery pagination plugin. I wanna hide pagination panel (prev, curent, next buttons) when items on the page is too few to showed up the next page, I mean when items are only for first page.

this id from - https://github.com/gbirke/jquery_pagination

JS CODE

 (function($){
    /**
     * @class Class for calculating pagination values
     */
    $.PaginationCalculator = function(maxentries, opts) {
        this.maxentries = maxentries;
        this.opts = opts;
    }

    $.extend($.PaginationCalculator.prototype, {
        /**
         * Calculate the maximum number of pages
         * @method
         * @returns {Number}
         */
        numPages:function() {
            return Math.ceil(this.maxentries/this.opts.items_per_page);
        },
        /**
         * Calculate start and end point of pagination links depending on 
         * current_page and num_display_entries.
         * @returns {Array}
         */
        getInterval:function(current_page)  {
            var ne_half = Math.floor(this.opts.num_display_entries/2);
            var np = this.numPages();
            var upper_limit = np - this.opts.num_display_entries;
            var start = current_page > ne_half ? Math.max( Math.min(current_page - ne_half, upper_limit), 0 ) : 0;
            var end = current_page > ne_half?Math.min(current_page+ne_half + (this.opts.num_display_entries % 2), np):Math.min(this.opts.num_display_entries, np);
            return {start:start, end:end};

Available Options

next_show_always

If this is set to false, the "Next"-link is only shown when the page number can be increased. Default: true

prev_show_always

If this is set to false, the "Previous"-link is only shown when the page number can be decreased. Default: true

num_display_entries

Maximum number of pagination links that are visible. Set to 0 to display a simple "Previous/Next"-Navigation. Set to an odd number for maximum symmetry and aesthetic pleasure. Default: 11

if (content.length<perPage){
//pass those options to the class
}

EDIT and since apparantly giving the solution isn't enough, I've put the all the code neatly together for you to just copy&paste now:

Less than number of items per page: http://jsfiddle.net/niklasvh/EQVBv/

More than number of items per page: http://jsfiddle.net/niklasvh/EQVBv/20/
