1.直接上代碼
<!doctype html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Document</title>
<!-- CSS樣式 -->
<style type="text/css">
td {
border: blue 1px solid;
}
</style>
<!-- JS實現 -->
<script type="text/javascript">
document.write("99乘法表");
document.write("<br />");
document.write("<table algin='center'>");
for (var i = 1; i <= 9; i++) {
document.write("<tr>");
for (var j = 1; j <= i; j++) {
document.write("<td>" + j + "*" + i + "=" + (j * i) + "</td>");
}
document.write("</tr>");
}
document.write("</table>");
</script>
</head>
<body>
</body>
</html>
2.運行截圖
