分页链接

标签: javascript html pagination

我已经在我的网站上添加了分页插件,但是我不知道如何添加页面链接以及在何处添加它们。由于每当我刷新任何页面时,我所有的内容都在同一个页面中,因此它会返回索引页面。我仍然在Java语言方面还是个菜鸟,不知道该怎么做。任何帮助将不胜感激。

<script type="text/javascript">
$(document).ready(function(){

    //how much items per page to show
    var show_per_page = 9; 
    //getting the amount of elements inside content div
    var number_of_items = $('#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
    $('page1').val(0);
    $('#show_per_page').val(show_per_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 active_page" href="javascript:go_to_page(' + current_link +')" longdesc="' + current_link +'">'+ (current_link + 1) +'</a>';
        current_link++;
    }
    navigation_html += '<a class="next_link active_page" 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').removeClass('active_page');

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

    //and show the first n (show_per_page) elements
    $('#content').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
    $('#content').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);


}

</script>
<input type='hidden' id='current_page'/>
    <input type='hidden' id='show_per_page'/>
   <div id="content">
   //content of my website
   </div>

  <div id='page_navigation'> 
  </div>
