各位兄弟帮忙看看这个代码问题出在哪啊

目的就是想得到时间 然后每秒刷新 就达到了时间在走动的动态效果 但是不知道就是为什么不动  求教导
<html>
       <head>
<script language="JavaScript">
function timeTest(){
var time = new Date();
var hour = time.getHours();
var minutes = time.getMinutes();
var second = time.getSeconds();
document.write(hour+":"+minutes+":"+second);
setTimeout("timeTest()",1000);
}
</script>
</head>
<body onload="timeTest();">
</body>
</html>

    楼主 你运行你的代码，右键 查看源文件，document.write 把页面重写了.
    <html>
           <head>
        <script language="JavaScript">
            function timeTest(){
                var time = new Date();
                var hour = time.getHours();
                var minutes = time.getMinutes();
                var second = time.getSeconds();
               // document.write(hour+":"+minutes+":"+second);   
    document.getElementById('test').innerHTML = hour+":"+minutes+":"+second
                setTimeout("timeTest()",1000);
                }
        </script>
    </head>
    <body onload="timeTest();" id="test">
    </body>
    </html>

    if((min>0)&&(flag==0))

    document.forms.input1.value=hou+"时"+min+"分"+sec+"秒";
