您需要
setInterval在点击处理程序范围内将的返回值设置为变量，然后
clearInterval()像这样使用：
var interval = null;$(document).on('ready',function(){ interval = setInterval(updateDiv,3000);});function updateDiv(){ $.ajax({ url: 'getContent.php', success: function(data){ $('.square').html(data); }, error: function(){ clearInterval(interval); // stop the interval $.playSound('oneday.wav'); $('.square').html('<span >Connection problems</span>'); } });}
