How do I do two jquery-ajax processes at the same time?

I am trying to call 2 functions on the same page to send jquery-ajax at the same time to handle a delta task (function 1 is to make new records to the database, function 2 is to read the database every 5 seconds and then display records from the database in the table in html).

Before I go to function 1, the page works fine with a call to function 2 to read the records and display the records on the page every 5 seconds, but as soon as I call function 1 to enter new records, function 2 seems to be waiting in the queue and only run process after function 1. However, I'm pretty sure the problem is not because the database is locked, but function 1 is starting new records.

Does anyone know how I can handle jquery-ajax at the same time? See below for more details on my code:

HTML:

<table style='width:100%' border="0">
    <tr>
        <td width="120"><input onclick="submitAction()" type="button" value="Process"></td>
    </tr>
</table>

<script>
    var myInterval = setInterval('getUpdatedRecord()', 5000);
</script>

      

        
        
        
      

    

JavaScript:

function submitAction()
{
    var paramList = "Action=make_process";

    ajaxRequest = $.ajax({
        url: "ord_process.php",
        type: 'POST',
        data: paramList,
        error: function(){
             msgObj.innerHTML = '<div style="width:313px; padding-top:40px;"><p class="cAlign">Connecton error.<br>Please try again.</p></div>';
                },
        success: function(data){
         var endDateTime = getCurrentDateTime();
         msgObj.innerHTML = ''; 
        alert("  "+data+"\n\n  Start Date&Time : "+startDateTime+"\n    End Date&Time : "+endDateTime)
            }   
     });    
}



function getUpdatedJobRecord()
{
    var paramList = "Action=get_job_record&call=ajax";

    ajaxRequest = $.ajax({
            url: "ord_process.php",
            type: 'POST',
            data: paramList,
            error: function(){
                msgObjB.innerHTML = update_date;
                msgObjA.innerHTML = '<td><div style="width:313px; padding-top:40px;"><p class="cAlign">Connecton error.<br>Please try again.</p></div></td>';
            },
            success: function(data){
                msgObjB.innerHTML = update_date;
                msgObjA.innerHTML = data;
            }       
    }); 
}
