我的情况类似于:

switch (text) {
  case SOME_CONSTANT || ANOTHER_CONSTANT:
    console.log('Case 1 entered');

  break;

  case THIRD_CONSTANT || FINAL_CONSTANT:
    console.log('Case 2 entered');

  break;

  default:
    console.log('Default entered');
}

总是输入默认大小写。如果你遇到了类似的多例switch语句问题，你要找的是:

switch (text) {
  case SOME_CONSTANT:
  case ANOTHER_CONSTANT:
    console.log('Case 1 entered');

  break;

  case THIRD_CONSTANT:
  case FINAL_CONSTANT:
    console.log('Case 2 entered');

  break;

  default:
    console.log('Default entered');
}

添加并澄清Stefano的答案，您可以使用表达式动态地设置switch中的条件值，例如:

var i = 3
switch (i) {
    case ((i>=0 && i<=5) ? i : -1):
        console.log('0-5');
        break;

    case 6: console.log('6');
}

在你的问题中，你可以这样做:

var varName = "afshin"
switch (varName) {
    case (["afshin", "saeed", "larry"].indexOf(varName)+1 && varName):
      console.log("hey");
      break;

    default:
      console.log('Default case');
}

虽然很干…

你可以这样写:

switch (varName)
{
   case "afshin": 
   case "saeed": 
   case "larry": 
       alert('Hey');
       break;

   default: 
       alert('Default case');
       break;
}         

你可以这样做:

alert([
  "afshin", 
  "saeed", 
  "larry",
  "sasha",
  "boby",
  "jhon",
  "anna",
  // ...
].includes(varName)? 'Hey' : 'Default case')

或者只是一行代码:

alert(["afshin", "saeed", "larry",...].includes(varName)? 'Hey' : 'Default case')

这比埃里克的回答有所改善

其中一个可能的解决方案是:

const names = {
afshin: 'afshin',
saeed: 'saeed',
larry: 'larry'
};

switch (varName) {
   case names[varName]: {
       alert('Hey');
       break;
   }

   default: {
       alert('Default case');
       break;
   }
}

我是这样使用的:

switch (true){
     case /Pressure/.test(sensor): 
     {
        console.log('Its pressure!');
        break;
     }

     case /Temperature/.test(sensor): 
     {
        console.log('Its temperature!');
        break;
     }
}
