好的,我可以为您提供一段JavaScript代码来打印倒序九九乘法表:
```js
for (var i=9; i>=1; i--) {
var row = '';
for (var j=9; j>=i; j--) {
row += i + 'x' + j + '=' + (i*j) + ' ';
}
console.log(row);
}
```
运行这段代码,将会输出以下九九乘法表:
```
9x9=81 9x8=72 9x7=63 9x6=54 9x5=45 9x4=36 9x3=27 9x2=18 9x1=9
8x8=64 8x7=56 8x6=48 8x5=40 8x4=32 8x3=24 8x2=16 8x1=8
7x7=49 7x6=42 7x5=35 7x4=28 7x3=21 7x2=14 7x1=7
6x6=36 6x5=30 6x4=24 6x3=18 6x2=12 6x1=6
5x5=25 5x4=20 5x3=15 5x2=10 5x1=5
4x4=16 4x3=12 4x2=8 4x1=4
3x3=9 3x2=6 3x1=3
2x2=4 2x1=2
1x1=1
```
希望能对您有所帮助!

使用javascript打印出九九乘法表
以下是使用 JavaScript 打印九九乘法表的代码:
```javascript
for (var i = 1; i <= 9; i++) {
var row = "";
for (var j = 1; j <= i; j++) {
row += i + " * " + j + " = " + i*j + " ";
}
console.log(row);
}
```
输出结果如下:
```
1 * 1 = 1
2 * 1 = 2 2 * 2 = 4
3 * 1 = 3 3 * 2 = 6 3 * 3 = 9
4 * 1 = 4 4 * 2 = 8 4 * 3 = 12 4 * 4 = 16
5 * 1 = 5 5 * 2 = 10 5 * 3 = 15 5 * 4 = 20 5 * 5 = 25
6 * 1 = 6 6 * 2 = 12 6 * 3 = 18 6 * 4 = 24 6 * 5 = 30 6 * 6 = 36
7 * 1 = 7 7 * 2 = 14 7 * 3 = 21 7 * 4 = 28 7 * 5 = 35 7 * 6 = 42 7 * 7 = 49
8 * 1 = 8 8 * 2 = 16 8 * 3 = 24 8 * 4 = 32 8 * 5 = 40 8 * 6 = 48 8 * 7 = 56 8 * 8 = 64
9 * 1 = 9 9 * 2 = 18 9 * 3 = 27 9 * 4 = 36 9 * 5 = 45 9 * 6 = 54 9 * 7 = 63 9 * 8 = 72 9 * 9 = 81
```
使用javascript 打印九九乘法表
以下是使用 JavaScript 打印九九乘法表的代码:
```javascript
for (var i = 1; i <= 9; i++) {
var row = "";
for (var j = 1; j <= i; j++) {
row += i + " x " + j + " = " + i * j + " ";
}
console.log(row);
}
```
运行上述代码,将会在控制台输出如下九九乘法表:
```
1 x 1 = 1
2 x 1 = 2 2 x 2 = 4
3 x 1 = 3 3 x 2 = 6 3 x 3 = 9
4 x 1 = 4 4 x 2 = 8 4 x 3 = 12 4 x 4 = 16
5 x 1 = 5 5 x 2 = 10 5 x 3 = 15 5 x 4 = 20 5 x 5 = 25
6 x 1 = 6 6 x 2 = 12 6 x 3 = 18 6 x 4 = 24 6 x 5 = 30 6 x 6 = 36
7 x 1 = 7 7 x 2 = 14 7 x 3 = 21 7 x 4 = 28 7 x 5 = 35 7 x 6 = 42 7 x 7 = 49
8 x 1 = 8 8 x 2 = 16 8 x 3 = 24 8 x 4 = 32 8 x 5 = 40 8 x 6 = 48 8 x 7 = 56 8 x 8 = 64
9 x 1 = 9 9 x 2 = 18 9 x 3 = 27 9 x 4 = 36 9 x 5 = 45 9 x 6 = 54 9 x 7 = 63 9 x 8 = 72 9 x 9 = 81
