Question

document.getElementById('AllButton').onclick = switchAll;

function illuminateRed() {
  clearLights();
  document.getElementById('stopLight').style.backgroundColor = "red";
}

function illuminateOrange() {
  clearLights();
  document.getElementById('slowLight').style.backgroundColor = "orange";
}

function illuminateGreen() {
  clearLights();
  document.getElementById('goLight').style.backgroundColor = "green";
}

function illuminateRedOrange() {
  clearLights();
  document.getElementById('stopLight').style.backgroundColor = "red";
  document.getElementById('slowLight').style.backgroundColor = "orange";
}

function illuminateBlack() {
  clearLights();

}

function clearLights() {
  document.getElementById('stopLight').style.backgroundColor = "black";
  document.getElementById('slowLight').style.backgroundColor = "black";
  document.getElementById('goLight').style.backgroundColor = "black";
}

var clickTimes = 0;
var change = 1;

function switchAll() {
  clickTimes++;
  switch (clickTimes) {
    case 1:
      clearLights();
      document.getElementById('stopLight').style.backgroundColor = "red";
      break;
    case 2:
      clearLights();
      document.getElementById('stopLight').style.backgroundColor = "red";
      document.getElementById('slowLight').style.backgroundColor = "orange";
      break;
    case 3:
      clearLights();
      document.getElementById('goLight').style.backgroundColor = "green";
      break;
    case 4:
      clearLights();
      document.getElementById('slowLight').style.backgroundColor = "orange";
      break;
    case 5:
      clearLights();
      document.getElementById('stopLight').style.backgroundColor = "red";
      break;
    case 6:
      document.getElementById('stopLight').style.backgroundColor = "black";
      document.getElementById('slowLight').style.backgroundColor = "black";
      document.getElementById('goLight').style.backgroundColor = "black";

这是我的 ICT 类(class)作业，我们必须构建一个交通信号灯系统，我的代码目前可以正常工作。但是，一旦我按下屏幕上的按钮并且每次点击都在可能的组合之间循环，交通灯就完成了它的序列，它不会再重复了。我想知道是否有人可以帮助我让它循环，我将不胜感激，谢谢，我是编码新手，如果它关闭了，我很抱歉。

只需在最后一个 break 之前写入 clickTimes = 0;。
