Let’s say I have a line of code that looks like this:
setInterval(ajaxFunction,3000);
where ajaxFunction is a function that calls a PHP script and returns something. If this request happens to take longer than 3 seconds, what happens? will It terminate the current request and start over, or will it start a 2nd request and have both running at once? (or some other behavior I haven’t thought of)
They will overlap. Your second ajax call will begin before the first one completes.
