jQuery delay not working

Question

$('.transparent').removeClass('transparent').delay(2000).addClass('not_transparent').delay(4000) 

I have a div that is semi transparent and then want to switch it to not transparent. But the jQuery .delay(); method doesn't seem to work here. I've tried .fadeIn(); instead and that works with a delay but it doesn't work the changing classes.

Answer 1

.delay() is used for items that are part of a queue, like animations. A simple addClass is not queued.

You could use setTimeout.

var trans = $('.transparent').removeClass('transparent'); setTimeout(function() {     trans.addClass('not_transparent'); }, 2000); 

As an alternative, you could add the non-queued item to the queue using .queue(), though I think a setTimeout would be better.

$('.transparent').removeClass('transparent').delay(2000).queue(function(nxt) {       $(this).addClass('not_transparent');       nxt(); }); 

Answer 2

I know this is an old question, but there's still a lot of traffic coming here from google so I'll add my two cents;

You could use something like -

$('.transparent').fadeIn().delay(500).queue(function(){    $('.transparent').addClass('yourclass');  });

You can pass a function to the queue in order to execute them after the delay. Have been using this myself for very similar examples.
