Receive Jquery and PHP response from second to second

Galley,

I have a page in PHP that makes a query in the database at the end of the processing I show the amount of records updated. This process takes a while, in my Jquery I only show the total of affected records, how could I change my Jquery to show time to time, in case every 1 second it shows the user the amount of records.

EDIT: ATTENTION I can not keep calling the PHP page several times, I need to call a single time and listen to her or receiving data from her!

var form_data = new FormData();

         form_data.append('id', idSel);
         $.ajax({
             url: 'postar_reenvio.php', // caminho para o script que vai processar os dados
             type: 'POST',
             data: form_data,
             cache: false,
             contentType: false,
             processData: false,
             beforeSend: function () {
                $('.resp').html("<img src='images/spin.gif' alt='Notificação' height='70' width='70'/> <br>Enviando Mensagens, aguarde!");
            },
             success: function(response) {

Creates a function that makes this control. And success use the setTimeout to set the time to call this function again

In my PHP page I only use echo($cont); I wanted to put an echo inside the Loop I have on the PHP page and every 1 second and reply to Jquery

@abfurlan It is not equal pq the question that you posted it keeps calling the function "site" I do not want to call the function again, I want to get the data from the PHP page.

I believe that for the purpose you want, a Websocket is much better than ajax requests of 1 in 1 second. With websocket Voce would see in real time.

You would make your own script that is running the querys to send the information through the socket channel.

In php you can use these examples:

I believe that in the function itself

beforeSend();

You can create a loop stating the amount of records entered. (If I understood it that way).

By clicking on the button I want to keep receiving PHP data with echo($cont); Beforesend serves in the case of the upload image I used in the example.

You can use the window.setInterval JS to call the function passing as parameter the function you want to call and the time in milliseconds.

The Code would look like this:

var intervalo = window.setInterval(consulta, 1000);
function consulta() {
   var form_data = new FormData();
     form_data.append('id', idSel);
     $.ajax({
         url: 'postar_reenvio.php', // caminho para o script que vai processar os dados
         type: 'POST',
         data: form_data,
         cache: false,
         contentType: false,
         processData: false,
         beforeSend: function () {
            $('.resp').html("<img src='images/spin.gif' alt='Notificação' height='70' width='70'/> <br>Enviando Mensagens, aguarde!");
        },
         success: function(response) {
        }
   }

And if you want to abort the script use clearInterval(intervalo);.
