问题 I'm trying to call clearInterval inside setInterval function, which is doing some ajax fetching, without any luck. var nre = setInterval('checkit()',5000); $(function() { checkit = function(){ $.post("check.php", { login: "<?php echo $_SESSION['login'];?>" }, function( data ) { if (data == 1) { $('#debug').html(data); window.clearInterval(nre); } }); } }); The point is, that the loop wont break, although recieves positive data to do so.
