how to call php script with ajax that doesnt need a response

Question

I'm trying to implement a timer e.g. time spent online. This will be correct to the nearest minute. Every 60 seconds it will add +1 to the minutes column for the user in the db table.

var timer = 60000;
setInterval(function(){isOnline()},timer);

will call the isOnline() function and from this function i want to call the php script updateTime.php. This script does not return anything it simply updates the db +1. I have validation and stuff on this to stop cheating but on a basic level I don't know how to make an Ajax call that doesn't return something. I have found an ajax function that works onclick but i need this to be called by the setInterval and not to bother the user.

$(function isOnline() 
{
    $(#).load("updateTime.php?ID=<php echo $id;?>");
})

I was trying something like this but it isn't getting triggered. Anyone got any advice for this?

usually this is done with one ajax call in the document.unload event handler. — hek2mgl

simply use $.post :)

$(function isOnline() 
{
    $.post("updateTime.php?ID=<php echo $id;?>");
})

Use $.get():

setInterval(function(){
    $.get("updateTime.php", { ID: "<php echo $id;?>"} );
}, 60000);
