Question

我正在使用Jquery在我的页面上对一些div进行分页。目前，分页显示为：

上一页1 2 3 4 5 6 7 8 9下一页

如何自定义它以仅显示上一个和下一个按钮：prev next ?????

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);
}

Answer 1

如果您要使用其他人的代码，至少从更好的来源获取它。您使用的代码绝对不是高质量的。

要删除中间的所有链接，只需删除以下代码块：

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++;
}

祛瘀

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++;
    }

Jquery Pagination只显示prev和next
