[jQuery] Re: kill the cpu

[Josh Nathanson]

Rather than call the function recursively, you might want to use setInterval 
rather than setTimeout, which is what I think you are trying to 
achieve...that is, run the function once per second.

I think if you run the function recursively without an "exit strategy" you 
get a circular behavior which is probably why the CPU is getting hammered.

Subject: [jQuery] kill the cpu



can this code kill a cpu?


$(function() {
   show_clock();
});

function showtime() {
   var meses = new 
Array("ENE","FEB","MAR","ABR","MAY","JUN","JUL","AGO","SEP","OCT","NOV","DIC");
   var dias = new 
Array("DOMINGO","LUNES","MARTES","MIERCOLES","JUEVES","VIERNES","SABADO","DOMINGO");

   var d=new Date();
   var seconds = d.getSeconds();
   var minutes = d.getMinutes();
   var hours   = d.getHours();
   var ampm = (hours >= 12) ? " PM" : " AM";
   var week = dias[d.getDay()];
   var mes = meses[d.getMonth()];
   var dia = d.getDate();
   var anio = d.getFullYear();

   hours = ((hours > 12) ? hours - 12 : hours);
   minutes = ((minutes <  10) ? "0" : "") + minutes;
   seconds = ((seconds <  10) ? "0" : "") + seconds;

   $('.year').text(anio);
   $('.day').text(dia);
   $('.month').text(mes);
   $('.week').text(week);
   $('span.h').text(String(hours));
   $('span.minute').text(String(minutes));
   $('span.seconds').text(String(seconds));
   $('.ampm').text(ampm);

   setTimeout('showtime()', 1000);
}

the problem is the     setTimeout('showtime()', 1000);
if i uncomment the show_clock() the cpu usage is normal, but is not, the 
cpu usage is at 50%+ in ie6.
