Am trying to refresh data stored in a div every 10 seconds using jQuery.
My HTML code is:
<!DOCTYPE html>
<head>
<title>Untitled Document</title>
<script src="http://code.jquery.com/jquery-latest.js"></script>
<script>
$(document).ready(function(){
setInterval(function() {
$("#latestData").load("getLatestData.php #latestData");
}, 10000);
});
</script>
</head>
<body>
<div id = "latestData">
</div>
</body>
</html>
And the PHP code I am using (temporarily as I know this won't change due to the same "data"):
<?php
echo "test";
?>
However, it isn't even showing "test" on the html page.. could anyone suggest where I have gone wrong?
Many thanks
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);
});
