<script type="text/javascript">
var attime;
function cloc(){
var time=new Date();
attime= time.getHours()+":"+time.getMinutes()+":"+time.getSeconds() ;
document.getElementById("clock").value = attime;
}
//setInterval("cloc()",1000);
</script>
请问为何注释setInterval("cloc()",1000);后运行不能显示日期？

}

<body>
<p id="clock"></p>
<button onmouseover="cloc()">鼠标经过</button>
</body>
我这个可以啊，就是注释掉不自动刷新了
