Timeout jQuery effects


Question

I am trying to have an element fade in, then in 5000 ms fade back out again. I know I can do something like:

setTimeout(function () { $(".notice").fadeOut(); }, 5000);

But that will only control the fade out, would I add the above on the callback?

Update: As of jQuery 1.4 you can use the .delay( n ) method. http://api.jquery.com/delay/

$('.notice').fadeIn().delay(2000).fadeOut('slow'); 

Note: $.show() and $.hide() by default are not queued, so if you want to use $.delay() with them, you need to configure them that way:

$('.notice')
    .show({duration: 0, queue: true})
    .delay(2000)
    .hide({duration: 0, queue: true});

You could possibly use the Queue syntax, this might work:

jQuery(function($){ 

var e = $('.notice'); 
e.fadeIn(); 
e.queue(function(){ 
  setTimeout(function(){ 
    e.dequeue(); 
  }, 2000 ); 
}); 
e.fadeOut('fast'); 

}); 

or you could be really ingenious and make a jQuery function to do it.

(function($){ 

  jQuery.fn.idle = function(time)
  { 
      var o = $(this); 
      o.queue(function()
      { 
         setTimeout(function()
         { 
            o.dequeue(); 
         }, time);
      });
  };
})(jQuery);

which would ( in theory , working on memory here ) permit you do to this:

$('.notice').fadeIn().idle(2000).fadeOut('slow');

I just figured it out below:

$(".notice")
   .fadeIn( function() 
   {
      setTimeout( function()
      {
         $(".notice").fadeOut("fast");
      }, 2000);
   });

I will keep the post for other users!

Great hack by @strager. Implement it into jQuery like this:

jQuery.fn.wait = function (MiliSeconds) {
    $(this).animate({ opacity: '+=0' }, MiliSeconds);
    return this;
}

And then use it as:

$('.notice').fadeIn().wait(2000).fadeOut('slow');

You can do something like this:

$('.notice')
    .fadeIn()
    .animate({opacity: '+=0'}, 2000)   // Does nothing for 2000ms
    .fadeOut('fast');

Sadly, you can't just do .animate({}, 2000) -- I think this is a bug, and will report it.

Ben Alman wrote a sweet plugin for jQuery called doTimeout. It has a lot of nice features!

Check it out here: jQuery doTimeout: Like setTimeout, but better.

To be able to use it like that, you need to return this. Without the return, fadeOut('slow'), will not get an object to perform that operation on.

I.e.:

  $.fn.idle = function(time)
  {
      var o = $(this);
      o.queue(function()
      {
         setTimeout(function()
         {
            o.dequeue();
         }, time);
      });
      return this;              //****
  }

Then do this:

$('.notice').fadeIn().idle(2000).fadeOut('slow');
