innerHtml應該改為innerHTML，getInterval應該是setInterval：
<script type="text/javascript"> ?
????? var num=document.getElementById("seconds").innerHTML;
????? function clock(){
????????? num--;
????????? document.getElementById("seconds").innerHTML=num;
????????? if (num == 1){
????????????? window.location.assign("http://www.xianlaiwan.cn");
????????? }
?????? ?
????? }
??? ?
????? var i= setInterval(clock,1000);
????? </script>
