使用JavaScript和CSS实现不同行颜色的九九乘法表
源代码：
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>乘法九九表</title>
<style>
table{
background-color: grey;
}
#odd{
background-color:blue ;
}
#even{
background-color: red;
}
</style>
</head>
<body>
<script type="text/javascript">
document.write("")
for (var i = 1; i < 10; i++) {
document.write("")
for (var j = 1; j <= i; j++) {
if(i%2==0){
document.write("")
document.write(j + "*" + i + "=" + j * i + " ");
document.write(" ")
}
else if(i%2!=0){
document.write("")
document.write(j + "*" + i + "=" + j * i + " ");
document.write(" ")
}
}
document.write(" ")
}
document.write("
")
</script>
</body>
</html>
