以下是JavaScript实现的99乘法表:
```javascript
for (let i = 1; i <= 9; i++) {
let row = "";
for (let j = 1; j <= i; j++) {
row += `${j} * ${i} = ${i * j}\t`;
}
console.log(row);
}
```
输出:
```
1 * 1 = 1
1 * 2 = 2 2 * 2 = 4
1 * 3 = 3 2 * 3 = 6 3 * 3 = 9
1 * 4 = 4 2 * 4 = 8 3 * 4 = 12 4 * 4 = 16
1 * 5 = 5 2 * 5 = 10 3 * 5 = 15 4 * 5 = 20 5 * 5 = 25
1 * 6 = 6 2 * 6 = 12 3 * 6 = 18 4 * 6 = 24 5 * 6 = 30 6 * 6 = 36
1 * 7 = 7 2 * 7 = 14 3 * 7 = 21 4 * 7 = 28 5 * 7 = 35 6 * 7 = 42 7 * 7 = 49
1 * 8 = 8 2 * 8 = 16 3 * 8 = 24 4 * 8 = 32 5 * 8 = 40 6 * 8 = 48 7 * 8 = 56 8 * 8 = 64
1 * 9 = 9 2 * 9 = 18 3 * 9 = 27 4 * 9 = 36 5 * 9 = 45 6 * 9 = 54 7 * 9 = 63 8 * 9 = 72 9 * 9 = 81
```
在这个实现中,我们使用了两个for循环来生成乘法表。外部循环从1到9遍历每一行,内部循环从1到当前行数遍历每一列。我们使用字符串插值来构建每一行,然后使用console.log()函数将其打印到控制台上。
