<script>
    //jquery的post
    $.post
    (
        'server.asp',
        {
            Act:'DoSubmit',
            UserName:escape('明凯博客'),//进行编码
           WebSite:'www.aimks.com'
        },
        function(data)
        {
            alert(unescape(data));//对返回数据进行解码
        }
    );    
</script>
