前端js代码：

autoinit(0,4)
functionrefresh(pageindex){
varparent=document.getElementById("contentlist");
while(parent.childNodes.length>2){
parent.removeChild(parent.lastChild);
}
autoinit(pageindex,4)
}

functionautoinit(pageindex,pagesize){
$.ajax({
type:"post",url:"<%=request.getContextPath()%>/servletpage",data:{"pageindex":pageindex,"pagesize":pagesize},success:function(returndata){
varreturndata=eval(returndata);
for(vari=0;i<pagesize;i++){
newtr=document.createElement("tr");
newtdtitle=document.createElement("td");
newtdtitle.innerHTML=returndata[i].title;
newtdtime=document.createElement("td");
newtdtime.innerHTML="";
newtduser=document.createElement("td");
newtduser.innerHTML=returndata[i].user;
newtr.appendChild(newtdtitle);
newtr.appendChild(newtdtime);
newtr.appendChild(newtduser);
document.getElementById("contentlist").appendChild(newtr)
}
}
});

后台处理：

intpageindex=Integer.parseInt(request.getParameter("pageindex"));
intpagesize=Integer.parseInt(request.getParameter("pagesize"));
try{
List<Info>infos=newInfoDao().getInfos(pageindex,pagesize);
JSONArrayja=newJSONArray();
for(inti=0;i<infos.size();i++){
JSONObjectjo=newJSONObject();
jo.put("title",infos.get(i).getTitle());
jo.put("user",infos.get(i).getPubuser());
ja.add(jo);
}
PrintWriterout=response.getWriter();
out.print(ja);
}catch(ClassNotFoundException|sqlExceptione){
//TODOAuto-generatedcatchblock
e.printStackTrace();
