This time I will show you how to achieve the paging effect of AJAX and what are the precautions to achieve the paging effect of AJAX. The following is a practical case, let's take a look.

I recently wrote a function to add roles to user groups. It requires unadded roles on one side and added roles on the other, as well as a search function. After clicking add, ajax saves the operation.

Consider the function to be paging for the query function. The paging bar below has a total of 2*2 and 4 ajax...

The JS code is as follows:

$(document).ready(function() {
  App.init();
  currentRole(); // 当前角色
  currentRolePage();//当前角色分页
  noAddRole(); //未添加角色
  noAddRolePage();//未添加角色分页
 });
//当前角色列表
function currentRole(){
  var currentRoleCheckName =$("#currentRoleCheckName").val();
  // 当前角色的list集合
  $.ajax({
  async:true, 
  type:"POST", 
  //date:"groupId=rose",//发送到服务器的数据
  url:"${ctx}/group/ajax_showRolesForGroup.do",//请求路径
  data:{"groupId":groupId, 
  "page":page1,
  "checkName":currentRoleCheckName
  },
  dataType:"json", //返回数据的类型
  success:function(data){ //成功响应后的回调函数
  var result =data.pageSupport.items;
  console.log(data.pageSupport)
  var s="";
  for(var i in result){ 
   s+="<tr class=&#39;odd gradeX&#39;><td>"+result[i].name+"</td>"
   +"<td>"+result[i].remark+"</td>"
   +"<td><button type=&#39;button&#39; class=&#39;btn btn-xs btn-info m-r-5&#39; onclick=&#39;to_RemoveRoleToGroup("+result[i].roleId+");&#39;>移除</button></td></tr>";
  }
  $("#currentRole").html(s);
  }
 });
 }
//当前角色的分页
 function currentRolePage(){
  var currentRoleCheckName =$("#currentRoleCheckName").val();
  var totalPage=0;
  $.ajax({
  async:true, 
  type:"POST", 
  //date:"groupId=rose",//发送到服务器的数据
  url:"${ctx}/group/ajax_showRolesForGroup.do",//请求路径
  data:{"groupId":groupId, 
  "page":page1,
  "checkName":currentRoleCheckName
  },
  dataType:"json", //返回数据的类型
  success:function(data){ //成功响应后的回调函数
  totalPage=data.pageSupport.last;
  console.log(totalPage)
  var i= 0;
  var a="";
  for( i=page1-2; i<=page1+2;i++){
  if(i>0 && i<=totalPage){
   if(i == 1){
   $("#prev1").attr(&#39;class&#39;,&#39;disabled&#39;); 
   }
   if(page1 == i){
   a+="<li class=&#39;active&#39; bs1=&#39;" + i + "&#39;><a>"+i+"</a></li>";
   }else{
   a+="<li class=&#39;zhong1&#39; bs1=&#39;" + i + "&#39;><a href=&#39;javascript:void(0);&#39; onclick=&#39;a_method("+i+");&#39; >"+i+"</a></li>";
   }
  }
  }
  $("#fy_list").html(a);
  }
 });
 }
 //中间页 
 function a_method(i) {
  page1 = i;
  currentRole(); // 当前角色
  currentRolePage();//当前角色分页
 }
//查询操作
function currentRoleCheck(){
 page1=1;
 currentRole(); // 当前角色
 currentRolePage();//当前角色分页
 }
