Refresh a div with php data every 10 seconds using jQuery
jQuery load method works in a different way. Try reading its documentation.
You don't have to specify destination element ID twice, remove the second one, like this:
$("#latestData").load("getLatestData.php");
Here's a way that will solve what you want to achieve, using the $.get method in jQuery:
$(document).ready(function () { setInterval(function() { $.get("getLatestData.php", function (result) { $('#latestData').html(result); }); }, 10000);});
If you want to refresh message count just use this code:
$(document).ready(function () { setInterval(function () { $("#ID").load(); }, 1000);});
