jquery slide and timing

Question

hey there, i have a div that expands when the page is loaded, now i need it to collapse after 30 seconds, does anybody have an idea about how to do it in query?

$(function(){
    $("#banner").slideDown(); 
    });

Answer 1

$(function(){
    $("#banner").slideDown(function() {
        setTimeout(function() {
            $("#banner").slideUp();
        }, 30000);
    });
});

Answer 2

To do this you'll need to use setTimeout

$(function(){
        //something
        setTimeout("slidedown()",30000);
}

function slidedown(){
   $("#banner").slideDown()
}
