為什么不顯示時(shí)間？
function clock(){
????? var time=new Date();????????????? ??? ? ?
????? document.getElementById("clock").value = time;
?? }
???? val i=setInterval("clock()",1000);
</script>
</head>
<body>
? <form>
??? <input type="text" id="clock" size="50"? />
??? <input type="button" value="Stop" onclick="clearInterval(i)" />

i前面的var寫錯(cuò)了，你寫的是val
