JQUERY, appending an LI to a UL, and then animating that LI

I have an UL:

<ul id="news-feed">.....</ul>

I'd like to be able to append a LI to the top of the list and have that appended item slideDown into place.

$("#news-feed").append('<li">This is my item</li>').hide().slideDown();

Problem I'm having is the above code is sliding the news-feed item down, and not the appended item. Any ideas?

If you were hoping to chain it all together, you can use appendTo() instead. It will return the new <li> element so you can slide it down.

$('<li>This is my item</li>').appendTo("#news-feed").hide().slideDown();

EDIT: As @cletus noted, you should use .prependTo() as he did in his answer instead of .appendTo(). This will bring the new item to the top of the list.

If you want to chain it together nicely, flip it around and use prependTo() instead of prepend(). Either:

$("<li>").text("This is my item").hide().prependTo("#news-feed").slideDown();

or

$("<li>This is my item</li>").hide().prependTo("#news-feed").slideDown();

I prefer the first because it handles escaping. The second doesn't. But it's largely a matter of preference.

Usually we take it this way:

var newsItem = $("<ul></ul>"); // Create a template item and clone from it

var parentItem = $( /* whatever selector string */ );

//  …

newsItem.clone().text("blah").hide().appendTo(parentItem).toggle('slide');

Also, when you say “add to the top of the list”, usually prepend() works better as expected.

Yes, first you need to make it display none, then make it slide down:

$("#news-feed").append('<li style="display:none">This is my item</li>').find('li:last').slideDown();

If that doesn't work, break it into two statements:

$('#news-feed').append('<li style="display:none">This is my item</li>');
$('#news-feed li:last').slideDown();
