Timeout jQuery effects
JqueryTimeoutJquery Problem Overview
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?
Jquery Solutions
Solution 1 - Jquery
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');
Solution 2 - Jquery
I just figured it out below:
$(".notice")
.fadeIn( function()
{
setTimeout( function()
{
$(".notice").fadeOut("fast");
}, 2000);
});

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');
Solution 4 - Jquery
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.
Solution 6 - Jquery
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');
Solution 7 - Jquery
This can be done with only a few lines of jQuery:
$(function(){
// make sure img is hidden - fade in
$('img').hide().fadeIn(2000);
// after 5 second timeout - fade out
setTimeout(function(){$('img').fadeOut(2000);}, 5000);
});
see the fiddle below for a working example...
