是否可以将字符串和整数值一起传递给 switch 语句中的 case

Question

我假设有两个答案，一个是字符串，另一个是尝试将开关与逻辑运算符结合使用的整数。这是我所拥有的，当我提供一个数字 1 时，它没有输出相关的答案。有什么办法可以做到吗？

如何接受以字符串或整数形式给出的答案？

我忘了添加这行代码

  var test = prompt('your fav number ?');
user.toUpperCase();

    switch(test) {
case  'one', 1:
    var numberSentence = 'one';
    var numbernumber = 1;
    if(numberSentence === 'one' && numbernumber === 1) {
        console.log('you got the answer') ; 
    }else {
        console.log('pls try again');
    }
    break;
case 'two':
    var twoSentence = 'two';
    var twoNumber = 2;
    if (twoSentence === 'two' || twoNumber === 2 ){
        console.log('Cool you got it right');
    }else {
        console.log('do u want try again?');    
    }
    console.log('it is two awesome' );
    break;
case 'seven':
    console.log('seven is my fav number as well ');
    break;
default:
console.log('you could have at least said smth.');
}

您不能将两个值放在单个 case 语句中，但可以使用 fall-through。如果您正在获取用户输入，它始终是一个字符串，即使他们输入的是数字，所以您应该将其放在引号中。

test = prompt("Please type a number");
switch (test) {
  case "1":
  case "one":
    alert("That's the first number");
    break;
  case "2":
  case "two":
    alert("Second place isn't as good");
    break;
  case "3":
  case "three":
    alert("Three is a magic number");
    break;
  default:
    alert("I don't know that number");
}

当 case 没有以 break 结束时，它只是继续下一个案例。这允许您使用相同的代码处理多个案例。
