JavaScript实现时间显示器

<script>
			function show(){
				var date = new Date();
				var year = date.getFullYear();
				var month = date.getMonth()+1;
				month = month<10?"0"+month:month;
				var week = date.getDay();
				week = "日一二三四五六".charAt(week);
				week = "星期"+week;
				var day = date.getDate();
				day = day<10?"0"+day:day;
				var hour = date.getHours();
				hour = hour<10?"0"+hour:hour;
				var minutes = date.getMinutes();
				minutes = minutes<10?"0"+minutes:minutes;
				var seconds = date.getSeconds();
				seconds = seconds<10?"0"+seconds:seconds;
				var result = year+","+month+","+day+" "+week+" "+hour+":"+minutes+":"+seconds;
				document.getElementById("time").innerHTML = result;
			}
			show();
			setInterval("show()",1000);

外部html 代码如下：

			<span id="time"></span>

此时即可实现
