jQuery - Append multiple elements one after the other - jquery-ui

Question

I'm looking to create a nice effect when appending multiple paragraphs to a div. When I append I want to fadeIn the paragraphs one at a time so one shows after the other. At the moment they all fade in at the same time.
example html;
<div class="wrapper">
<p class="para">paragraph 1</p>
<p class="para">paragraph 2</p>
<p class="para">paragraph 3</p>
</div>
Here is the code used to append to the div
$(results).prependTo(".wrapper").hide().fadeIn('slow');
(Results) is simply the multiple paragraphs.
Thanks in advance for your help and advice.

Answer 1

You could try something like this:
$(results).bind('appear', function(){ // bind a custom event
$(this).fadeIn('slow', function(){
$(this).next('p.para').trigger('appear'); // recurse
});
})
.prependTo('wrapper')
.end() // back to "results"
.hide() // not necessary if already hidden by style rule
.first().trigger('appear'); // start the cascade
Here's an example: http://jsfiddle.net/redler/CDbEn/

Answer 2

You could use queue() for this:
$('p').prependTo("#wrapper").hide().each(function() {
var element = $(this);
$('#wrapper').queue(function() {
setTimeout(function() {
element.fadeIn('slow');
$('#wrapper').dequeue();
}, 700);
});
});
Example.

Answer 3

//assuming resuls is an array of strings containing your p's
var appear = function(index) {
if (results[index])
$(results[index]).prepend('.wrapeer').hide().fadeIn('slow', function(){ appear(index+1); });
}

Answer 4

What about
$('.para').each(function(index){
$(this).hide().prependTo('.wrapper').delay(500 * index).fadeIn('slow');
});
