js实现九九乘法表代码如下：

<!DOCTYPE html>
<html>
	<head>
		<meta charset="utf-8">
		<title>Nearth</title>
		<script type="text/javascript">
			document.write("<table>");
			for(var i=1;i<=9;i++){
				document.write("</br>");
				document.write("<tr>");
				for(j=1;j<=i;j++){
					document.write("<td>"+i+"*"+j+"="+i*j+"&nbsp&nbsp&nbsp"+"</td>");
				}
				document.write("</tr>");	
			}
			document.write("</table>");
		</script>
	</head>
	<body>
		
	</body>
