我需要这个jquery / ajax脚本每30秒运行一次[重复]

• What's the easiest way to call a function every 5 seconds in jQuery? [duplicate] 7 answers

Now I have been puzzling with this for some time. I got part of it together in jquery/ajax:

<script type="text/javascript">
$(document).ready(function(){
    jQuery.ajax({
        type: "GET",
        url: "sessioncheck.php",
        dataType:"json",
        success:function(response){
            if (response) {
                window.location.href = 'logout.php';
            }
            else {
                // Process the expected results...
            }
        }

    });
});
</script>

This works perfectly, but I would like this process to repeat itself every 30 seconds. Can someone please help me with that? I have read something about setinterval, but I cant seem to get it to work.

Thanks a lot in advance for all of your help!

$(document).ready(function(){
    setInterval(function() {
        jQuery.ajax({
            type: "GET",
            url: "sessioncheck.php",
            dataType:"json",
            success:function(response){
                if (response) {
                    window.location.href = 'logout.php';
                }
                else {
                    // Process the expected results...
                }
            }

        });
    }, 30000);
});
