jQuery getting just added by ajax element

$.post('includes/script.php', $(this).serialize(), function(data) {
    $('body').append(data);
});

alert ($('#new').length)

php script is <php echo "<div id="new">text</div>" ?>

it alerts 0, so it can't see new div.

How can you make it see new div?

You have to wait till your post is done before you can check the length. Do something like this:

$.post('includes/script.php', $(this).serialize(), function(data) {
    var newItem = $(data).appendTo('body');
    alert (newItem.length);
});

How are you calling it? I get alert 1 in Firefox, Chrome, and IE. Note that "function" was misspelled in your code snippet.

<script type="text/javascript" src="jquery-1.4.2.js"></script>
<script type="text/javascript">

$(document).ready( function() {
addnew();
});

function addnew (){
    $('body').append('<div id="new">text</div>');
    alert ($('#new').length)
}
</script>
