OnClick焦点在Textfield中带动画

Question

我尝试过专注没有动画，并且完美无缺。 像这样：

document.forms['search_form'].elements['search'].focus()

我想做什么？：

I am using Animation (Which is working Perfect). So how can i set Focus into 
the **textfield** with Animation.

这样做的目的：

So that i dont have to click into the textfield for typing anything in it.

这是我的CODE DEMO：

Answer 1

$('a').click(function(){
    $('html, body').animate({
        scrollTop: $('#search').offset().top
    }, 500);
    $("#search").focus();
    return false;
});
