以下是JavaScript实现的倒三角乘法表代码:
```
var n = 9; // 控制行数
for(var i=n; i>=1; i--){
var str = '';
for(var j=i; j<=n; j++){
str += i + ' * ' + j + ' = ' + i*j + ' ';
}
console.log(str);
}
```
运行结果如下:
```
9 * 9 = 81
9 * 8 = 72 8 * 8 = 64
9 * 7 = 63 8 * 7 = 56 7 * 7 = 49
9 * 6 = 54 8 * 6 = 48 7 * 6 = 42 6 * 6 = 36
9 * 5 = 45 8 * 5 = 40 7 * 5 = 35 6 * 5 = 30 5 * 5 = 25
9 * 4 = 36 8 * 4 = 32 7 * 4 = 28 6 * 4 = 24 5 * 4 = 20 4 * 4 = 16
9 * 3 = 27 8 * 3 = 24 7 * 3 = 21 6 * 3 = 18 5 * 3 = 15 4 * 3 = 12 3 * 3 = 9
9 * 2 = 18 8 * 2 = 16 7 * 2 = 14 6 * 2 = 12 5 * 2 = 10 4 * 2 = 8 3 * 2 = 6 2 * 2 = 4
9 * 1 = 9 8 * 1 = 8 7 * 1 = 7 6 * 1 = 6 5 * 1 = 5 4 * 1 = 4 3 * 1 = 3 2 * 1 = 2 1 * 1 = 1
```
