基于jquery编写分页插件_jquery

$.fn.mypagination = function(totalProperty,opts){ opts = $.extend({ perPage:10, callback:function(){ } },opts||{}); return this.each(function(){ function numPages(){ return Math.ceil(totalProperty/opts.perPage); } function selectPage(page){ return function(){ currPage = page; if (page<0) currPage = 0; if (page>=numPages()) currPage = numPages()-1; render(); $('img.page-wait',panel).attr('src','images/wait.gif'); opts.callback(currPage+1); $('img.page-wait',panel).attr('src','//m.sbmmt.com/m/faq/images/nowait.gif'); } } function render(){ var html = '' +'' +'' +'' +'' +'' +'' +'' +'
第页/共'+numPages()+'页
检索到'+totalProperty+'记录
