ajax分页小功能（table）尚不完善，在更新。

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

function autoinit(pageindex,pagesize){
$.ajax({
type:"post",
url:"<%=request.getContextPath()%>/servletpage",
data:{"pageindex":pageindex,"pagesize":pagesize},
success:function(returndata){
var returndata = eval(returndata);
for(var i = 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)
}
}
});

int pageindex = Integer.parseInt(request.getParameter("pageindex"));
int pagesize = Integer.parseInt(request.getParameter("pagesize"));
try {
List<Info> infos = new InfoDao().getInfos(pageindex,pagesize);
JSONArray ja = new JSONArray();
for(int i = 0 ; i < infos.size(); i++){
JSONObject jo = new JSONObject();
jo.put("title", infos.get(i).getTitle());
jo.put("user", infos.get(i).getPubuser());
ja.add(jo);
}
PrintWriter out = response.getWriter();
out.print(ja);
} catch (ClassNotFoundException | SQLException e) {
