Question

我有html表，并为它工作正常做了分页，但我想显示像5这样的寻呼机然后点击＆gt;＆gt;这个箭头必须显示下一个5，因为当我有更多的数据时，它会给冗长的寻呼机占用更多的空间。这是我的fiddle

任何人都可以建议我如何解决这个问题

Answer 1

如下所示，只需添加一个函数adjustPager，如果我没有误解这个问题，它就能正常工作。

$.fn.pageMe = function(opts){
             var $this = this,
                 defaults = {
                     perPage: 10,
                     showPrevNext: false,
                     hidePageNumbers: false
                 },
                 settings = $.extend(defaults, opts);

             var listElement = $this;
             var perPage = settings.perPage; 
             var children = listElement.children();
             var pager = $('.pager');

             if (typeof settings.childSelector!="undefined") {
                 children = listElement.find(settings.childSelector);
             }

             if (typeof settings.pagerSelector!="undefined") {
                 pager = $(settings.pagerSelector);
             }

             var numItems = children.size();
             var numPages = Math.ceil(numItems/perPage);

             pager.data("curr",0);

             if (settings.showPrevNext){
                 $('<li><a href="#" class="prev_link">«</a></li>').appendTo(pager);
             }

             var curr = 0;
             while(numPages > curr && (settings.hidePageNumbers==false)){
                 $('<li><a href="#" class="page_link">'+(curr+1)+'</a></li>').appendTo(pager);
                 curr++;
