Additionally, in jQuery 1.4 there will be a .delay() method:
// Based off of the plugin by Clint Helfers, with permission.
// http://blindsignals.com/index.php/2009/07/jquery-delay/
delay: function( time, type ) {
time = jQuery.fx ? jQuery.fx.speeds[time] || time : time;
type = type || "fx";
return this.queue( type, function() {
var elem = this;
setTimeout(function() {
jQuery.dequeue( elem, type );
}, time );
});
},
