PHP JQuery - Load multiple DIV's with 1 request

Question

My site currently has to load 6 different PHP pages to fill info for 7 DIV's.

Some refresh every 5 seconds, some every second.

I would rather load the one single PHP page every second, and split the details to all of the DIV's. That way only 1 request is sent per second, rather than 3 or 4 requests.

so --> api/getdata.php will echo: "$5.93, $10.36, 27:31 1, 22, Joe". Then JQuery will need to split each comma to a different DIV. Something like this:

setInterval(function() {$('#balance, #pot, #timer, #round, #id, #username').load('api/getdata.php');}, 1000);

I had a look on Google, but couldn't find anything to what I am looking for.

My current method (very bad) is:

<script type="text/javascript">
        $(document).ready(function() {
            $.ajaxSetup({ cache: false }); // This part addresses an IE bug. without it, IE will only load the first number and will never refresh
            $('#GetBalance, #GetBalanceWithdraw').load('get/GetBalance.php');
            $('#Clock').load('get/Clock.php');
            $('#GetPot').load('get/GetPot.php');

            setTimeout(function() {$('#errmsg').fadeOut('slow');}, 5000);
            setInterval(function() {
            $('#GetPot').load('get/GetPot.php');
            $('#TotalBids').load('get/TotalBids.php');
            }, 2500); 
            setInterval(function() {$('#GetBalance, #GetBalanceWithdraw').load('get/Balance.php');}, 5000);
            setInterval(function() {$('#GetBalance').load('get/Balance.php');}, 5000);
            setInterval(function() {$('#Clock').load('get/Clock.php');}, 1000);
        });
    </script>

So you will need to split your response and only then assign to elements. At this moment you add same value to all elements.

You need something like this:

setInterval(function() {
    $.get( 'api/getdata.php', function( data ) {
        var result = data.split( ', ' );
        $( '#balance' ).text( result[ 0 ] );
        $( '#pot' ).text( result[ 1 ] );
        $( '#timer' ).text( result[ 2 ] );
        $( '#round' ).text( result[ 3 ] );
        $( '#id' ).text( result[ 4 ] );
        $( '#username' ).text( result[ 5 ] );
    } );
}, 1000);

But in this case you can flood you server with requests if back-end will slow with response, so better to call new AJAX after 1 second after previous loaded using recursive function:

function updateData() {
    $.get( 'api/getdata.php', function( data ) {
        var result = data.split( ', ' );
        $( '#balance' ).text( result[ 0 ] );
        $( '#pot' ).text( result[ 1 ] );
        $( '#timer' ).text( result[ 2 ] );
        $( '#round' ).text( result[ 3 ] );
        $( '#id' ).text( result[ 4 ] );
        $( '#username' ).text( result[ 5 ] );
        setTimeout( updateData, 1000);
    } );
}
updateData();

Thanks! That's very simple. My site currently gets slower and slower as time goes on. That is perfect.

If you have all your strings in one string and comma separated, you could do this:

$( "#result" ).load( "ajax/test.html", function(data) {
  spread_the_news(data);
});

and then

function spread_the_news(data)
{
  var res = data.split(",");
  update_div_0_with_data(res[0]);
  update_div_1_with_data(res[1]);
  ...
}
