I want to use the methode .delay() to wait 1 sec before changing the content of an element. In my page, I have a button and when the ajax request is done, the button diplays "done". After that, I want to wait 1 sec and display "download". But the problem is that "download" is displayed immediately after the "done" without the delay.

Here is my code :

 $('#chocobo').click(function(){
   $('#chocobo').html('<div id="banana" class="fa fa-refresh fa-spin"></div>&nbspLoading');
   $.post("includes/modlist/pack.php",function(data){
        //$('#banana').addClass("fa-spin");
        $('#chocobo').addClass('done');
        $('#chocobo').html('<div id="banana" class="fa fa-check"></div>&nbspDone');
        $('#chocobo').delay(1000).html('<div id="banana" class="fa fa-refresh"></div>&nbspDownload');        
   });
});

Can someone help me please ?

I don't think leveraging delay() is best used here. You're fine with just using a setTimeout. Observe the following...

[...]

$('#chocobo').html('<div id="banana" class="fa fa-check"></div>&nbspDone');

setTimeout(function() {
    $('#chocobo').html('<div id="banana" class="fa fa-refresh"></div>&nbspDownload');  
}, 1000);

[...]

The .delay() method is best for delaying between queued jQuery effects. Because it is limited—it doesn't, for example, offer a way to cancel the delay—.delay() is not a replacement for JavaScript's native setTimeout function, which may be more appropriate for certain use cases.

See the delay() docs for example usages and scenarios

The jQuery delay function is used for things added to a queue, like steps of an animation. You could try using the setTimeout instead to get the effect you're looking for:

setTimeout(function(){ 
  $('#chocobo').html('<div id="banana" class="fa fa-refresh"></div>&nbsp; Download');
}, 1000); // 1000 being 1s in ms

EDIT: Whoops! I was too slow. Erlaunis has the better answer anyway too.

However, you can use it on this way, with callback function for fadeIn(), if you don't want to use setTimeout():

http://jsfiddle/ufsxaxm3/1/

$( "#chocobo" ).html('<div id="banana" class="fa fa-check"></div>&nbspDone').fadeIn('slow', function() {
$('#chocobo').html('<div id="banana" class="fa fa-refresh"></div>&nbspDownload').delay(1000).fadeIn(1000);
  });;

So, you need some jquery effect/animation, and then delay() will work as you wish...
