Question

我已经说过两个答案，一个是字符串，另一个是整数，试图使用带逻辑运算符的开关。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。有没有办法实现这个目标？

如果以字符串或整数形式给出答案，如何接受答案？

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.');
}

您不能在一个case语句中放置两个值，但可以使用直通。如果你收到用户输入，它总是一个字符串，即使他们输入一个数字，所以你应该把它放在引号中。

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");
}

如果case未以break结尾，则只会继续下一个案例。这允许您使用相同的代码处理多个案例。

是否可以将字符串和整数值一起传递给switch语句中的case
