<script type="text/javascript">

function countDown(){

time.value=t;

var inter = setInterval("countDown()",1000);
//window.onload=countDown;
</script>
</head>
<body onload="countDown()">
<input type="text" readonly="true" value="5" id="time"/>
<!--也可以在这里写javascript代码，这样就不必在body标签中写onload="countDown()"。-->
