javascript - 如何在 div 单击时调用函数，以及正确使用开关？

我正在尝试制作一个游戏，当用户单击按钮/div(将来清除地板)时，用户将被发送到新的“楼层”，一个新的 div“亮起”(变黑)但我似乎无法让它工作。所以想法是通过单击 div，它会调用函数，它将变量级别提高 1，并且当开关运行时，它会亮起(将 div 变黑)许多 ID 为“floor1-”的 div 9"

var level = 1

function floor() {
  level += 1;
}
switch (floor) {
  case 1:
    if (level >= 1) {
      document.getElementById("floor1").style.color = "black";
    } else {
      document.getElementById("floor1").style.color = "white";
    }
    break;
  case 2:
    if (level >= 2) {
      document.getElementById("floor2").style.color = "black";
    } else {
      document.getElementById("floor2").style.color = "white";
    }
    break;
  case 3:
    if (level >= 3) {
      document.getElementById("floor3").style.color = "black";
    } else {
      document.getElementById("floor3").style.color = "white";
    }
    break;
  case 4:
    if (level >= 4) {
      document.getElementById("floor4").style.color = "black";
    } else {
      document.getElementById("floor4").style.color = "white";
    }
    break;
  case 5:
    if (level >= 5) {
      document.getElementById("floor5").style.color = "black";
    } else {
      document.getElementById("floor5").style.color = "white";
    }
  case 6:
    if (level >= 6) {
      document.getElementById("floor6").style.color = "black";
    } else {
      document.getElementById("floor6").style.color = "white";
    }
    break;
  case 7:
    if (level >= 7) {
      document.getElementById("floor7").style.color = "black";
    } else {
      document.getElementById("floor7").style.color = "white";
    }
    break;
  case 8:
    if (level >= 8) {
      document.getElementById("floor8").style.color = "black";
    } else {
      document.getElementById("floor8").style.color = "white";
    }
    break;
  case 9:
    if (level >= 9) {
      document.getElementById("floor9").style.color = "black";
    } else {
      document.getElementById("floor9").style.color = "white";
    }
    break;
  default:

    <div class="floor" id="floor4"></div>
    <div class="floor" id="floor5"></div>
    <div class="floor" id="floor6"></div>
    <div class="floor" id="floor7"></div>
    <div class="floor" id="floot8"></div>
    <div class="floor" id="floor9"></div>
  </div>
</body>

最佳答案

我稍微修改了代码。

在 floor() 函数中移动了 switch
将 color 更改为 backgroundColor。
去掉了所有的else，我觉得没必要
将 floot8 更改为 floor8
将level = 1更改为level = 0，这样函数就会进入case 1
<

不确定这是否是您想要的，但这点亮了直到最后一层的所有分区。由于我使用了您的原始格式，因此我没有费心优化代码

var level = 0;

function floor() {
  level += 1;
  switch (level) {
    case 1:
      if (level >= 1) {
        document.getElementById("floor1").style.backgroundColor = "black";
      }
      break;
    case 2:
      if (level >= 2) {
        document.getElementById("floor2").style.backgroundColor = "black";
      }
      break;
    case 3:
      if (level >= 3) {
        document.getElementById("floor3").style.backgroundColor = "black";
      }
      break;
    case 4:
      if (level >= 4) {
        document.getElementById("floor4").style.backgroundColor = "black";
      }
      break;
    case 5:
      if (level >= 5) {
        document.getElementById("floor5").style.backgroundColor = "black";
      }
    case 6:
      if (level >= 6) {
        document.getElementById("floor6").style.backgroundColor = "black";
      }
      break;
    case 7:
      if (level >= 7) {
        document.getElementById("floor7").style.backgroundColor = "black";
      }
      break;
    case 8:
      if (level >= 8) {
        document.getElementById("floor8").style.backgroundColor = "black";
      }
      break;
    case 9:
      if (level >= 9) {
        document.getElementById("floor9").style.backgroundColor = "black";
      }
      break;
    default:
