How can i get these to fire one after another?

I've set this up all ready http://jsbin.com/ejese3/edit

I have these alert messages but at present if you click on another before the current alert is finished everything goes a bit mad. What I want to do 开发者_JS百科is have them queue up to fire 1 after another instead of overlapping.

Suggestions?

$('#messageDrop').addClass('visible').slideDown( 2000, 
    function(){ $(this).slideUp(2000, 
        function(){ $(this).removeClass('visible');
        }); 
    });

I'm not sure I understand the question, but jQuery functions such as slideUp() can take a callback method that will be fired after the operation is completed.

You can use the callback to show the next alert.

For what it's worth, jQuery code (such as in your example) that looks like:

$('#messageDrop').addClass('visible').slideDown().delay('2000').slideUp().removeClass('visible')

...is hard to read and maintain (IMO). Adding callbacks or nested callbacks increases this complexity. Consider declaring a few local variables and working with those objects rather than chaining a bunch of statements together.

Also, the stop() method is your friend when dealing with (potentially conflicting) jQuery animations: http://api.jquery.com/stop/
