使用Ajax进行分页，发布不起作用

I Use this code for paging

function changePagination(pageId,liId,modul,userid){
 $(".flash").show();
 var dataModul = 'modul='+modul;
 var dataUser = 'userid='+userid;
 var dataString = 'pageId='+ pageId;
 $.ajax({
       type: "POST",
       url: "loadDataVerifikasi.php",
       data: dataString,
       data: dataModul,
       data: dataUser,
       cache: false,
       success: function(result){
             $(".flash").hide();
             $(".link a").removeClass("In-active current") ;
             $("#"+liId+" a").addClass( "In-active current" );
             $("#pageData").html(result);
       }
  });}

And this for an action file with name loadDataVerifikasi.php

if(isset($_POST['pageId']) && !empty($_POST['pageId'])){
  $id=$_POST['pageId'];
}
else{
  $id='0';
}
$pageLimit=PAGE_PER_NO*$id;
$query="select * from pengajuan_".$_POST['modul']." join verifikasi on      pengajuan_".$_POST['modul'].".ketkdpengajuan = verifikasi.ketkdpengajuan where kdadmin = '".$_POST['userid']."' group by kdverifikasi limit $pageLimit,".PAGE_PER_NO;

But $_POST['modul'] post nothing,

I am not familiar with your syntax.

Please try:

function changePagination(pageId,liId,modul,userid){
$(".flash").show();
 var datastring = {
     modul: modul,
     userid: userid,
     pageId: pageId 
 }
 $.ajax({
       type: "POST",
       url: "loadDataVerifikasi.php",
       data: dataString,
       cache: false,
       success: function(result){
             $(".flash").hide();
             $(".link a").removeClass("In-active current") ;
             $("#"+liId+" a").addClass( "In-active current" );
             $("#pageData").html(result);
       }
 });
}

The $.ajax data attribute accepts an object with key-value pairs

I believe it is because you overwrite the data with dataUser. I haven't tested i but the code below should work. Also check out this for more info

function changePagination(pageId,liId,modul,userid){
 $(".flash").show();
 var dataModul = 'modul='+modul;
 var dataUser = 'userid='+userid;
 var dataString = 'pageId='+ pageId;
 $.ajax({
       type: "POST",
       url: "loadDataVerifikasi.php",
       data: { 'dataString':dataString, 'dataModul':dataModul, 'dataUser':dataUser },          
       cache: false,
       success: function(result){
             $(".flash").hide();
             $(".link a").removeClass("In-active current") ;
             $("#"+liId+" a").addClass( "In-active current" );
             $("#pageData").html(result);
