Question

So I am retrieving some data via POST using ajax, every 5 seconds, what I am trying to achieve is if the php file ouputs something, then stop the setInterval somehow or set it to 9999999.

Here is what I’ve tried:

var interval = DEFINEDFROMMYQL;
        $(function() {
            setInterval(function() {
                $.ajax({
                    type: "POST",
                    url: "url/file.php",
                    data: "whatever=2", 
                    success: function(html) {
                        $("#new").html(html);
                        if(html.lenght > 0) {
                            var interval = 99999999999999;
                        }
                   }
                });
            }, interval);
        });

I’m a newbie, so any help will be appreciated.

You can use clearInterval() to stop the timer started by setInterval and correct the typo html.lenght to html.length

// var interval = DEFINEDFROMMYQL;
$(function() {
yourInterval = setInterval(function() {
$.ajax({
           type: "POST",
           url: "url/file.php",
           data: "whatever=2", 
           success: function(html) {
                    $("#new").html(html);  

                    if(html.length > 0) {
                    ///var interval = 99999999999999;
                      clearInterval(yourInterval);
                    }
             }
         });
   }, interval);
});
