javascript - 動的ページネーション

Question

私は自分のウェブサイトの製品のページネーションにこのコードを使用しています。ここでの問題は、すべての製品が一度にロードされ、ページごとに 36 個の製品が表示されることです。

ここで私がしなければならないことは、一度に 36 個の製品をロードする必要があることです。次にクリックすると、次の 36 個をロードする必要があります。誰かがそれを手伝ってくれる？

    script type="text/javascript"> 
var jQuery12 = jQuery.noConflict();
jQuery12(document).ready(function(){
paginationhello();

});
function paginationhello(){

    //how much items per page to show
    var show_per_page = 36; 
    //getting the amount of elements inside content div
    var number_of_items = jQuery12('#content').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
    jQuery12('#current_page').val(0);
    jQuery12('#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>';

    jQuery12('#page_navigation').html(navigation_html);

    //add active_page class to the first page link
    jQuery12('#page_navigation .page_link:first').addClass('active_page');

    //hide all the elements inside content div
    jQuery12('#content').children().css('display', 'none');

    //and show the first n (show_per_page) elements
   jQuery12('#content').children().slice(0, show_per_page).css('display', 'block');
