jquery分頁只顯示上一頁和下一頁

Question

我正在使用jquery在頁面上分頁一些div。此刻的分頁顯示爲：

先前1 2 3 4 5 6 7 8 9下

如何可以定製，以只示出了一個和下一個鍵：前一個下一個?????

CODE：

// JavaScript Document 
$(document).ready(function(){ 

    //how much items per page to show 
    var show_per_page = 5; 
    //getting the amount of elements inside content div 
    var number_of_items = $('#paginationcontent').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 
    $('#paginationcontent').children().css('display', 'none'); 

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

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++; 
    } 

Answer 2

如果你要使用別人的代碼，從一個更好的來源至少得到它。你使用的代碼絕對不是高質量的。

要刪除所有鏈接在中間，只需刪除下面的代碼塊：

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++; 
}
