用Javascript打印九九乘法表

Sure, here's an example code to print the multiplication table in JavaScript:

for (var i = 1; i <= 9; i++) {
  var row = '';
  for (var j = 1; j <= i; j++) {
    row += `${j} x ${i} = ${i*j}\t`;
  }
  console.log(row);
}

This code will print the multiplication table from 1 to 9 in the console.

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：

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  

使用JavaScript打印九九乘法表

可以使用嵌套的 for 循环来打印九九乘法表，以下是使用 JavaScript 实现的代码：

for (let i = 1; i <= 9; i++) {
  let row = '';
  for (let j = 1; j <= i; j++) {
    row += i + '*' + j + '=' + i*j + ' ';
  }
  console.log(row);
}

输出结果为：

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
