Javascript 具有大于运算符的Switch Case语句？

我的代码中的以下IF语句不起作用。在这种情况下，如何在Switch Case格式或IF语句中添加“大于”运算符？我需要它告诉我，如果机器是1并且numOfBends>7，那么setupMins=60。如果机器为2且数值大于7，则setupMins=60。如果机器为3且数值大于7，则setupMins=60

/**
 * bendingSetupHours
 * @customfunction bendingSetupHours
 * @param {number} numOfBends 
 * @param {number} bendLengthInches 
 * @returns {number} bendingSetupHours
 */
function bendingSetupHours(numOfBends, bendLengthInches) {
  var machine;
  var setupMins;
  switch(bendLengthInches) {
    case 1: case 2: case 3: case 4: case 5: case 6: case 7: case 8: case 9: case 10: case 11: case 12: case 13: case 14: case 15: case 16:

    case 32: case 33: case 34: case 45: case 36:
      machine = 1;
      break;
    case 37: case 38: case 39: case 40: case 41: case 42: case 43: case 44: case 45: case 46: case 47: case 48: case 49: case 50: case 51:

    case 67: case 68: case 69: case 70: case 71:
      machine = 2;
      break;
    case "":
      machine = 0;
      break;
  default:
      machine = 3;
  } 
  switch("" + machine + numOfBends) {
      case "" + 1 + 0: case "" + 1 + 1: case "" + 1 + 2: case "" + 1 + 3: case "" + 2 + 0: case "" + 2 + 1: case "" + 2 + 2: case "" + 2 + 3:

        setupMins = 30;
        break;
      if (numOfBends >7 && machine ==1) {
        setupMins = 60;
        break;
      }
      case "" + 2 + 5: case "" + 2 + 6: case "" + 2 + 7:
        setupMins = 45;
        break;
      if (numOfBends >7 && machine ==2) {
        setupMins = 90;
        break;
      }
      case "" + 3 + 4: case "" + 3 + 5: case "" + 3 + 6: case "" + 3 + 7:
        setupMins = 60;

          setupMins = 120;
          break;
        }
    default:
      setupMins = 0;
  }
     return (setupMins / 60); 
}

您需要的不仅仅是更正。

您在

语句运行之前将
中断
，如果
语句可以运行，并且是的，您绝对不应该在此处使用
开关
语句。您不能在
开关案例
语句中添加条件。你最好使用IF-ELSE链
