JavaScript，Typescript switch 语句:两种情况下运行相同代码的方式?

2022-01-19 00:00:00 switch-statement javascript typescript

有没有一种方法可以在不复制和粘贴的情况下将两个不同的 case 值分配给同一个代码块?比如68以下和40应该执行相同的代码，而30是不相关的.

Is there a way to assign two different case values to the same block of code without copy and pasting? For example, below 68 and 40 should execute the same code, while 30 is not related.

case 68:
   //Do something
break;

case 40:
   //Do the same thing
break;

case 30:
   //Do something different
break;

认为这样的事情应该有效(即使它显然没有)是不正确的吗?

Is it incorrect to think something like this should work (even though it obviously doesn't)?

case 68 || 40:
   //Do something
break;

case 30:
   //Do something else
break;

推荐答案

把它们一个接一个地放在一起就行了

Just put them right after each other without a break

switch (myVar) {
  case 68:
  case 40:
    // Do stuff
  break;

  case 30:
    // Do stuff
  break;
}
