本文实例讲述了jQuery pager.js 插件动态分页功能。分享给大家供大家参考,具体如下:
pager.js 代码
function Page(opt){ var set = $.extend({num:null,startnum:1,elem:null,callback:null},opt||{}); if(set.startnum>set.num||set.startnum<1){ set.startnum = 1; } var n = 0,htm = ''; var clickpages = { elem:set.elem, num:set.num, callback:set.callback, init:function(){ this.elem.next('div.pageJump').children('.button').unbind('click') this.JumpPages(); this.elem.children('li').click(function () { var txt = $(this).children('a').text(); var page = '', ele = null; var page1 = parseInt(clickpages.elem.children('li.active').attr('page')); if (isNaN(parseInt(txt))) { switch (txt) { case '下一页': if (page1 == clickpages.num) { return; } if (page1 >= (clickpages.num - 2) || clickpages.num <= 6 || page1 < 3) { ele = clickpages.elem.children('li.active').next(); } else { clickpages.newPages('next', page1 + 1); ele = clickpages.elem.children('li.active'); } break; case '上一页': if (page1 == '1') { return; } if (page1 >= (clickpages.num - 1) || page1 <= 3 || clickpages.num <= 6) { ele = clickpages.elem.children('li.active').prev(); } else { clickpages.newPages('prev', page1 - 1); ele = clickpages.elem.children('li.active'); } break; case '首页': if (page1 == '1') { return; } if (clickpages.num > 6) { clickpages.newPages('首页', 1); } ele = clickpages.elem.children('li[page=1]'); break; case '尾页': if (page1 == clickpages.num) { return; } if (clickpages.num > 6) { clickpages.newPages('尾页', clickpages.num); } ele = clickpages.elem.children('li[page=' + clickpages.num + ']'); break; case '...': return; } } else { // if ((parseInt(txt) >= (clickpages.num - 3) || parseInt(txt) <= 3) && clickpages.num > 6) { // clickpages.newPages('jump', parseInt(txt)); // } // ele = $(this); // } // page = clickpages.actPages(ele); // if (page != '' && page != page1) { // if (clickpages.callback){ // clickpages.callback(parseInt(page)); // } var i = parseInt(txt); if(isNaN(i)||(i<=0)||i>clickpages.num){ return; }else if(clickpages.num>6){ clickpages.newPages('jump',i);
