第二编辑:

我已经尝试这一功能,但似乎并没有得到期望的结果

function generatePages(currentPage, LastPage) {
    if (LastPage <= 5) {
        var pages = '';
        for(var i=1;i<=5;i++)
        {
            pages += "<a class='page-numbers' href='#'>" + i + "</a>"
        }
        $("#PagerDiv").append(pages);
    }
    if (LastPage > 5) {
        var pages = '';
        for (var i = 1; i <= 5; i++) {
            pages += "<a class='page-numbers' href='#'>" + i + "</a>"
        }
        $("#PagerDiv").append(pages);
    }
}

lastPagecurrentPage 值,请帮帮我得到这个...

有帮助吗?

解决方案

您正在寻找被称为“分页”和什么有(总是)一个jQuery插件,没有工作适合你:

(下载它 rel="noreferrer">这里)


编辑:因为你似乎没有能够得到它的工作,这里是单向的(几个不同的),您可以如何使用插件

<强>步骤1:从JSON数据像下面生成标记:

<div id="display">
    <!-- This is the div where the visible page will be displayed -->
</div>

<div id="hiddenData">
    <!-- This is the div where you output your records -->
    <div class="record">
        <!-- create one record-div for each record you have in your JSON data -->
    </div>
    <div class="record">
    </div>
</div>

的想法是一个页链接上点击时,各自的记录复制到所述显示格。因此,该插件提供一个pageSelect回调函数。的步骤2 是为了实现该功能,例如:

function pageselectCallback(pageIndex, jq){
    // Clone the record that should be displayed
    var newContent = $('#hiddenData div.record:eq('+pageIndex+')').clone();
    // Update the display container
    $('#display').empty().append(newContent);
    return false;
}

这将意味着你必须记录每一个页面。如果你想每页显示多条记录,你必须相应地修改上述功能。

<强>第三和最后的步骤是正确初始化整个事情。

function initPagination() {
    // Hide the records... they shouldn't be displayed
    $("#hiddenData").css("display", "none");
    // Get the number of records
    var numEntries = $('#hiddenData div.result').length;
    // Create pagination element
    $("#pagination").pagination(numEntries, {
        num_edge_entries: 2,
        num_display_entries: 8, // number of page links displayed 
        callback: pageselectCallback,
        items_per_page: 1  // Adjust this value if you change the callback!
    });
}

所以,你只需要事后从您的JSON数据生成的HTML标记,并调用init-功能。

这并不难,不是吗?

其他提示

耶@SLaks是正确的。没有什么太疯狂了这里。您将有2个变量currentPageNumber和lastPageNumber。

$("div.paginator").append("<a...>prev</a>");
$("div.paginator").append("<a...>1</a>");

for (x = (currentPageNumber - 2; x <= (currentPageNumber + 2); x++) {
    $("div.paginator").append("<a...>"+ x +"</a>");
} 

$("div.paginator").append("<a...>"+ lastPageNumber +"</a>");
$("div.paginator").append("<a...>next</a>");

// you could apply styles to and a tag in the div.paginator
// you could apply a special class to the a tag that matches the currentPageNumber 
// you can also bind some click events to each a tag and use the $(this).text() to grab the number of the page to go to

使用 插件。他们都容易html页插件。把一切都在html一次和分与其中的一个。

...添加两个新的隐藏的输入

<input type='hidden' id='current_page' />  
<input type='hidden' id='show_per_page' /> 

接着添加一个空div来创建分页控件

<!-- An empty div which will be populated using jQuery -->  
<div id='page_navigation'></div>

$(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 = $('#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
    $('#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
    $('#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);
}
