i think setinterval jquery.load 1 you're looking for
var table = $("#tableid"); // refresh every 5 seconds var refresher = setinterval(function() { table.load("/path/to/js.php"); }, 5000); or shorten with
var refresher = setinterval(table.load.bind(table, "/path/to/data"), 5000); if you'd ever stop refreshing data, (e.g.,) user leaves page open long time
// stop refreshing after 30 minutes settimeout(function() { cleartimeout(refresher); }, 1800000); if data load takes while, might want refresh x seconds after data loaded. using settimeout
var table = $("#tableid"); var refresh = function() { table.load("/path/to/js.php", function() { settimeout(refresh, 5000); }); }; refresh();
