jQuery分页+ Twitter Bootstrap

Question

我正在尝试修改Jquery分页(基于此Jquery分页教程 - 演示)以使用令人敬畏的twitter引导程序.

Twitter Bootstrap的标准分页设置如下所示,因此这是分页输出结构的目标.

<div class="pagination">
    <ul>
        <li class="prev disabled"><a href="#">&larr; Previous</a></li>
        <li class="active"><a href="#">1</a></li>
        <li><a href="#">2</a></li>
        <li><a href="#">3</a></li>
        <li><a href="#">4</a></li>
        <li><a href="#">5</a></li>
        <li class="next"><a href="#">Next &rarr;</a></li>
    </ul>
</div>

到目前为止,我可以通过更改html输出结构来使其工作,但由于我将输出更改<a>为<li>标记,因此活动突出显示无法正常工作.

这就是我现在卡在ATM的地方!

我仍然需要做以下事情:

• prev在第一页时禁用按钮
• 更改<li>页面时更改活动
• next在最后一页上禁用按钮
• 修复prev按钮,使其再次工作
• 修复下一个按钮,使其再次工作

下面是JsFiddle的链接- 不知何故它不起作用,但代码应该是正确的(与此代码相同)

Answer 1

这是标准的jQuery.pagination库,我已经修改它以使用twitter bootstrap.

创建div -

<div id="myPager" class="pagination"></div>

然后

$('#myPager').pagination(100,{callback:function(page,component){
    console.info(page);
}})

这是图书馆的代码.

jQuery.fn.pagination = function(maxentries, opts){
    opts = jQuery.extend({
        items_per_page:10,
        num_display_entries:10,
        current_page:0,
        num_edge_entries:0,
        link_to:"javascript:void(0)",
        first_text:"First",
        last_text:"Last",
        prev_text:"Prev",
        next_text:"Next",
        ellipse_text:"...",
        prev_show_always:true,
        next_show_always:true,
        callback:function(){return false;}
    },opts||{});

    return this.each(function() {
        /**
         * Calculate the maximum number of pages
         */
        function numPages() {
            return Math.ceil(maxentries/opts.items_per_page);
        }

        /**
         * Calculate start and end point of pagination links depending on 
         * current_page and num_display_entries.
         * @return {Array}
         */
        function getInterval()  {
            var ne_half = Math.ceil(opts.num_display_entries/2);
            var np = numPages();
            var upper_limit = np-opts.num_display_entries;
            var start = current_page>ne_half?Math.max(Math.min(current_page-ne_half, upper_limit), 0):0;
            var end = current_page>ne_half?Math.min(current_page+ne_half, np):Math.min(opts.num_display_entries, np);
            return [start,end];
        }

        /**
         * This is the event handling function for the pagination links. 
         * @param {int} page_id The new page number
         */
        function pageSelected(page_id, evt){
            current_page = page_id;
            drawLinks();
            var continuePropagation = opts.callback(page_id, panel);
            if (!continuePropagation) {
                if (evt.stopPropagation) {
                    evt.stopPropagation();
                }
                else {
                    evt.cancelBubble = true;
                }
            }
            return continuePropagation;
        }

        /**
         * This function inserts the pagination links into the container element
         */
        function drawLinks() {
            panel.empty();
            var list = jQuery("<ul></ul>");
            panel.append(list);

            var interval = getInterval();
            var np = numPages();
            // This helper function returns a handler function that calls pageSelected with the right page_id
            var getClickHandler = function(page_id) {
                return function(evt){ return pageSelected(page_id,evt); }
            }
            // Helper function for generating a single link (or a span tag if it's the current page)
            var appendItem = function(page_id, appendopts){
                page_id = page_id<0?0:(page_id<np?page_id:np-1); // Normalize page id to sane value
                appendopts = jQuery.extend({text:page_id+1, classes:""}, appendopts||{});
                if(page_id == current_page){
                    var clazz = appendopts.side ? 'disabled' : 'active';
                    var lstItem = jQuery("<li class='"+clazz+"'><a>"+(appendopts.text)+"</a></li>")
                }
                else
                {
                    var a = jQuery("<a>"+(appendopts.text)+"</a>")
                        .attr('href', opts.link_to.replace(/__id__/,page_id));;
                    var lstItem = jQuery("<li></li>")
                        .bind("click", getClickHandler(page_id));
                    lstItem.append(a);
                }
                if(appendopts.classes){lstItem.addClass(appendopts.classes);}
                list.append(lstItem);
            }
            // Generate "Previous"-Link
            if(opts.prev_text && (current_page > 0 || opts.prev_show_always)){
                appendItem(0, { text: opts.first_text, side: true });
                appendItem(current_page-1,{text:opts.prev_text, side:true});
            }
            // Generate starting points
            if (interval[0] > 0 && opts.num_edge_entries > 0)
            {
                var end = Math.min(opts.num_edge_entries, interval[0]);
                for(var i=0; i<end; i++) {
                    appendItem(i);
                }
                if(opts.num_edge_entries < interval[0] && opts.ellipse_text)
                {
                    jQuery("<li class='disabled'>"+opts.ellipse_text+"</li>").appendTo(list);

我完全忘记了这篇文章
但是我设法让它与以下代码一起工作：

// Based on http://stackoverflow.com/questions/1262919/jquery-active-class-assignment and http://stackoverflow.com/questions/2037501/javascript-add-class-when-link-is-clicked

$(function() {
    $('ul.nav li:first').addClass('active').show(); //Activate first tab
    $('li a').click(function(e) {
        //e.preventDefault();
        var $this = $(this);
        $this.closest('ul').children('li').removeClass('active');
        $this.parent().addClass('active');

        //Remove active from dropdown li
        $('.dropdown').removeClass('active');

        // Activate Home when clicked on the logo
        $('.thelogo').click(function()
            {
              $('.nav li').removeClass('active');
              $('.home').addClass('active');
            });
    });
});
