laypage+SpringMVC实现后端分页

<div id="log-list"></div>
<div id="page-list"></div>

function paging(curr){
  $.getJSON('/page', {
  page: curr || 1 //向服务端传的参数
  }, function(res){
   //此处输出内容
   var table = $("<table></table>");
   table.attr({class:"layui-table admin-table",id:"page"});

   var thead = $("<thead><tr><th>编号</th><th>姓名</th><th>行为</th><th>时间</th><th>操作</th></tr></thead>");
   table.append(thead);
   var tbody = $("<tbody></tbody>");
   tbody.attr({id:"content"});

   $(function(){
    var datas = res;
     $.each(datas,function(index,value){
     var tr = $("<tr></tr>");
     tr.append("<td>"+ (++index) + "</td>");
      tbody.append(tr);
      tr.append("<td>"+ value.staffName + "</td>");
      tbody.append(tr);
      tr.append("<td>"+ value.operation + "</td>");
