一、让图片飞

代码:<script type="text/javascript">
        $(function () {
            $(document).mousemove(function (e) {

                $('#im').css('position', 'absolute').css({ "left": e.pageX, "top": e.pageY });
            });
        });
    </script>


<img src="2.png" id="im" />

二、显示层

$('*').click(function (e) {
               alert(e.target.id);

            });

三、改变鼠标图片

cursor:url(图片地址);

四、好友面板

$(function () {

            $('#u1 li ul li').hide();

            $('#u1 li').click(function () {
                $('ul li', $(this)).show(500);
                $('ul li', $(this).siblings('li')).hide(500);
                $('#san').attr('src','音乐的路径');
            });
        });


<body>

<bgsound id="san" loop="0" src="">

    <div style=" width:200px; height:500px; border:1px solid red;">

        <ul id="u1" style=" list-style-type:none; margin:0; padding:0; text-align:center;">
            <li>

                </ul>
            </li>

四、层显示的不同效果

$(function () {

            $('#btnslideDown').click(function () {
                $('div').slideDown(500);
            });
            $('#btnslideUp').click(function () {
                $('div').slideUp(500);
            });
            $('#btnslideToggle').click(function () {
                $('div').slideToggle(500);
            });
            //=======================
            $('#btnfadeIn').click(function () {
                $('div').fadeIn(1000);
            });
            $('#btnfadeOut').click(function () {
                $('div').fadeOut(1000);
            });
            $('#btnfadeToggle').click(function () {
                $('div').fadeToggle(500);
            });

        });


body>
    <input type="button" name="name" value="slideDown" id="btnslideDown" />
    <input type="button" name="name" value="slideUp" id="btnslideUp" />
    <input type="button" name="name" value="slideToggle" id="btnslideToggle" />
    <input type="button" name="name" value="fadeIn" id="btnfadeIn" />
    <input type="button" name="name" value="fadeOut" id="btnfadeOut" />
    <input type="button" name="name" value="fadeToggle" id="btnfadeToggle" />

    <div style=" width:300px; height:200px; ">

    </div>
</body>

五、新闻面板

$(function () {
            $('#dvTab div:gt(0)').hide();
            $('#uu1 li').mouseover(function () {
                var tt = $(this).text();
                switch (tt) {
                    case '新闻': $('#dvNews').show().siblings('div').hide(); break;
                    case '图片': $('#dvPic').show().siblings('div').hide(); break;
                    case '深度': $('#dvDeep').show().siblings('div').hide(); break;
                    case '军事': $('#dvMl').show().siblings('div').hide(); break;
                }
            });
        });

六、动画

            });

           
        });
    </script>


<body>
    <input type="button" name="name" value="飞起来" id="btn" />
    <img src="2.png" style=" position:absolute;" />
</body>

七、cookie保存账号密码//google不支持本地cookie

<script src="jquery-1.8.3.js" type="text/javascript"></script>
    <script src="jquery.cookie.js" type="text/javascript"></script>
    <script type="text/javascript">
        $(function () {
            if ($.cookie('userName')==null ) {
                $('span').text('欢迎菜鸟登录');
            } else {
                $('span').text('欢迎'+$.cookie('userName')+'登录');
            }

            $('#btn').click(function () {

                $.cookie('userName', $('#txt').val());
            });
        });
    </script>


span>欢迎菜鸟登录</span>
    <input type="text" name="name" value="" id="txt" />
    <input type="button" name="name" value="记住密码" id="btn" />

八、高清图片//jqzoom插件
