滑动后显示/隐藏动画淡入淡出

Question

我试图在滑动后添加fadeIn / fadeOut动画：

http://jsfiddle.net/lamberta/e44kB/

我尝试添加和写入 .fadeOut(350, function () { & .fadeOut(350, function () {

但是没有工作，我无法弄清楚把它放在哪里，有人知道如何把它放在这里吗？

你可以通过

来做到这一点

脚本

function toggleSlider() {
    if ($("#demo").is(":visible")) {
        $("#hola").animate(
            {
                opacity: "0"
            },
            600,
            function(){
                $("#hola").slideUp();
            }
        );
    }
    else {
        $("#demo").slideDown(600, function(){
            $("#hola").animate(
                {
                    opacity: "1"
                },
                600
            );
        });
    }   
}

HTML

<a href="#" onclick="toggleSlider();">toggle</a>
<div id="demo" style="display:none;background:#eee;padding:10px;">
    <div id="hola" style="opacity:0;filter:alpha(opacity=0);">
