jquery的分页代码，是结合数据库实现的， 这里只给出核心jquery代码。其它的大家可以发挥下。
function pagerBar(dataCount,pageSize,serverUrl,contentPlace,pagerbarPlace,callBack){ this.dataCount = dataCount; this.pageSize = pageSize; this.serverUrl = serverUrl; this.contentPlace = $("#"+contentPlace); this.pagerbarPlace = $("#"+pagerbarPlace); this.callBack = callBack; this.pageCount = 0; this.pageIndex = 1; this.curInfo = $("<span/>"); this.prePage = $("<span/>"); this.nextPage = $("<span/>"); this.init(); } pagerBar.prototype = { init : function(){ this.getPageCount(); this.initLink(); this.showBarInfo(); if(this.pageCount>0){ this.setLink(1); } }, getPageCount : function(){ this.pageCount = parseInt(this.dataCount / this.pageSize); if(this.dataCount % this.pageSize !=0){ this.pageCount++; } }, initLink : function(){ var self = this; this.prePage = $("<span/>").html("上一页").addClass("pageLink"); this.prePage.click(function(){ self.setLink(self.pageIndex-1); }); this.nextPage = $("<span/>").html("下一页").addClass("pageLink"); this.nextPage.click(function(){ self.setLink(self.pageIndex+1); }); this.pagerbarPlace.append(this.curInfo).append(this.prePage).append(this.nextPage); }, showBarInfo : function(){ this.prePage.hide(); this.nextPage.hide(); if(this.pageCount==0){ this.curInfo.html("暂时没有信息!"); } else if(this.pageCount==1){ this.curInfo.html("1/1"); } else{ this.curInfo.html(this.pageCount + "/" + this.pageIndex); } }, setLink : function(i){ var self = this; $.ajax({ url:self.serverUrl, type:"get", data:{pageSize:self.pageSize,pageIndex:i}, cache:false, error:function(){ alert("数据加载失败!"); }, success:function(htmlData){ self.contentPlace.html(htmlData); if(self.pageCount==1){ self.prePage.hide(); self.nextPage.hide(); }else{ if(i==1){ self.prePage.hide(); self.nextPage.show(); }else if(i==self.pageCount){ self.prePage.show(); self.nextPage.hide(); }else{ self.prePage.show(); self.nextPage.show(); } } self.pageIndex = i; self.curInfo.html(self.pageCount+"/"+self.pageIndex); if(self.callBack){ self.callBack(); } } }); }, changeServerUrl : function(dataCount,serverUrl){ this.dataCount = dataCount; this.serverUrl = serverUrl; this.pageIndex=1; this.getPageCount(); this.showBarInfo(); this.contentPlace.html(""); if(this.pageCount>0){ this.setLink(1); } }, dataCountDec : function(){ this.dataCount--; this.getPageCount(); if(this.pageCount<this.pageIndex){ this.pageIndex = this.pageCount; } if(this.pageIndex>0){ this.setLink(this.pageIndex); } this.showBarInfo(); } } 详细出处参考：http://www.jb51.net/article/23857.htm
