Question

How to send Ajax request on every 1s using JQuery ?

Answer 1

The interval 1 sec is small enough and it can be that you will start the second request before you receive response to the first request. So you should either start the next request after receiving of the previous one (see the suggestion of Martin Jespersen) or save jqXHR from the previous $.ajax request in a variable and use it to abort the previous request (see here an example)
